, 1997) leaving epithelial cells of the intestine in a state of enhanced expression and production of pro-inflammatory cytokines (Maggio-Price et al., 2006). Excessive Smad 7 protein blocks TGF-β signaling

and maintains elevated pro-inflammatory cytokines in inflammatory bowel disease (IBD) patients, while silencing Smad7 expression restores the anti-inflammatory effects of TGF-β (Monteleone et al., 2001; Nguyen & Snapper, 2009). Additionally, IBD patients have high nuclear factor Kappa B (NF-κB) (Jobin and Sartor, 2000) and Smad7 protein expression (Monteleone et al., 2001, 2004a, b, c; Nguyen & Snapper, 2009), 5-Fluoracil which may be correlated with enhanced chronic colonic inflammation. Several studies have suggested a strong correlation between NF-κB and TGF-β/Smad pathways (Bitzer et al., 2000; Nagarajan et al., 2000; Haller et al., 2003). In lamina propria mononuclear cells isolated from IBD patients, abrogation of Smad7 with antisense oligonucleotides allowed endo-genous TGF-β to up-regulate inhibitor Kappa B-alpha (IκB-α) and lower NF-κB accumulation (Monteleone selleck chemical et al., 2004c). The probiotic (commensal intestinal microorganisms)-induced effect on the NF-κB signaling pathway is well established (Yoon and Sun, 2011). Sougioultzis et al. (2006) reported that Saccharomyces

boulardii, nonpathogenic yeast, inhibited interleukin 8 (IL-8) production, IκB-α degradation, reduced NF-κB DNA binding, and NF-κB reporter gene up-regulation of interleukin 1 (IL-1) in intestinal heptaminol cells in vitro. Oral administration of probiotics attenuate intestinal inflammation (Petrof et al., 2004; Tien et al., 2006; Mañé et al., 2009) and NF-κB activation induced by infection (Murphy et al., 2008), stress, tumor necrosis factor (TNF-α), and interleukin 1 (Petrof et al., 2004). Previously, we reported that inoculation of the probiotic L. acidophilus enhanced enteric protection to pathogens and reduced mucosal inflammation by enhancing TGF-β expression in mice (Chen et al., 2005). In the current study, by utilizing both in vivo (C. rodentium-mouse

model, a model of human infection of EPEC and EHEC E. coli) and in vitro approaches, we tested the hypothesis that early inoculation of probiotic L. acidophilus may enhance host-protective immunity to enteric bacterial pathogens through promoting TGF-β response, which exerts its anti-inflammatory effect by reducing Smad 7 expression, allowing TGF-β to up-regulate IκB-α and lower NF-κB accumulation, and that co-administration of prebiotics, the nondigestible food ingredients, which can stimulate the growth and/or activity of beneficial probiotic bacteria, may promote probiotic-induced anti-inflammatory effects. Six- to 8-week-old female and male BALB/c ByJ mice were purchased from the Jackson Laboratory (Bar Harbor, ME), bred in a specific pathogen-free facility at Massachusetts General Hospital (Charlestown, MA), and provided mouse chow and sterile water ad libitum.

In this report, we analyze results of the use of gracilis muscle free flap for reconstruction of OE defects and its feasibility for prosthetic rehabilitation. Nine consecutive patients treated at the China Medical University 3-Methyladenine mouse Hospital of Taichung during January 2009 to January 2013, who had gracilis free flap reconstruction after OEs, were retrospectively reviewed. Cancer in six patients and trauma in remaining three patients was the cause for OE. Nine patients who

underwent reconstruction with gracilis free tissue transfer had a successful outcome. There was not any donor or recipient site morbidity; however, one patient was deceased during follow-up period due to metastasis. The mean follow-up period was 23.5 months. Cosmetic results were acceptable both to patients and to surgeons. Gracilis free flap to repair OE defects may be a safe alternative for reconstruction. It provides a larger volume of well-vascularized tissue, greater placement flexibility, and minor donor site morbidity without any significant functional deficit. © 2014 Wiley Periodicals, Inc.

“Introduction: The aim of the presented study was to investigate nerve regeneration after application of C3-Toxin, a Rho-GTPase inhibitor and to correlate morphometry, neurophysiology, and function in an end-to-side peroneal/tibial nerve repair model of the rat. Materials and methods: Twenty rats with a peroneal to tibial end-to-side neurorrhaphy were divided into two groups: 1) control group, 2) C3 fusion toxin group with intrafascicular application of 1 μg/100 μl C3 fusion toxin. Survival

time was 8 weeks. Nerve conduction velocities and motor function were analyzed and histomorphological evaluation consisting of measurement of intraneural collagen level, axon count, total nerve area, myelination index, and N-ratio followed. Results: Evaluation of motor function and nerve conduction did not show any statistical differences. Histological analysis revealed higher axon count, thicker myelin sheaths, and higher myelination index in the C3 fusion toxin group (P < 0.001). Comparison of N-ratio and intraneural collagen level were without statistical significance. Conclusion: The current study shows that application of C3 fusion toxin leads to higher myelination and increases axonal sprouting. © 2012 Wiley Periodicals, Inc. Microsurgery, 2012.

Furthermore, three other cytokines, namely IFN-γ, IL-12 and IL-18, led Small molecule library to bystander activation of MP CD8+ T cells; the bystander activation effect of the latter two cytokines was likely mediated via induction of IFN-γ 3. Subsequently, it was shown that none of these cytokines were able to directly stimulate T cells in vitro, suggesting that these cytokines induced production of another, possibly common, effector cytokine that is able to activate T cells. This cytokine was shown

to be IL-15, which is produced and presented to T cells by APC upon stimulation with IFN-α/β and IFN-γ 4, 5 (Fig. 1). IL-15 preferentially stimulates MP CD8+ T cells – a consequence of MP CD8+ T cells expressing very high levels of CD122 4–7. CD122 is the common IL-2/IL-15 receptor β subunit, which together with the common γ chain (γc), is necessary for signal transduction upon IL-15 or IL-2 binding. Notably, heterologous CD44low naïve CD8+ T cells are also activated following virus infection 1,

8, although to a much lower extent than MP CD8+ T cells, which is possibly due to weaker IL-15-responsiveness conferred by intermediate expression levels of CD122 4. In contrast to the wealth of data available for the CD8+ compartment, CD4+ T-cell bystander activation has not been Sirolimus order as well characterized, at least until now. Bystander activation of CD4+ T cells PTK6 is less efficient as compared with that of CD8+ T cells; however, unrelated CD44high MP CD4+ T cells have been reported to undergo a low degree of bystander proliferation upon virus infection and following administration of poly(I:C) or LPS 1, 2, 9. This low degree of bystander activation found in MP CD4+ T cells may be a result of the cells’ intermediate

CD122 expression, which is comparable to CD122 levels on naïve CD8+ cells 4, 7. Bystander activation of MP CD4+ T cells has also been observed in mice receiving injection of the synthetic NKT cell ligand α-GalCer; this bystander effect was independent of IFN-α/β but required (at least partially) IFN-γ 9. Moreover, infection of mice with the parasite Leishmania donovani also led to proliferation of heterologous memory CD4+ T cells 10. In humans, Di Genova et al. 11 have previously shown that tetanus toxoid (TT)-booster vaccination of individuals induced not only the expansion of TT-specific memory CD4+ T cells but also the expansion of memory (but not naïve) CD4+ T cells specific for the purified protein derivative of tuberculin and Candida albicans, thus suggesting bystander activation of the non-TT-specific cells. In this issue of the European Journal of Immunology, Di Genova et al. revisit the issue of bystander activation in CD4+ T cells 12 using a mouse model to better understand the underlying mechanism involved.

Schizophrenia is a heterogenous psychotic syndrome which affects approximately 1% of the population. The aetiology of schizophrenia is multifactorial with both environmental

and genetic factors thought to play important roles [89]. The neuropathology of schizophrenia remains obscure; however, a number of structural abnormalities have been idenitified and confirmed by meta-analysis including ventricular enlargement and decreased cerebral (cortical and hippocampal) volume in the absence of gliosis [90]. The latter feature fuels support Selleck Vemurafenib for a neurodevelopmental contribution. Intriguingly, these morphological changes are similar to those observed in the developmental vitamin D deficient rat model, as previously described [27]. Further, NGF, neurotrophin, and p75NTR, known to be regulated

by vitamin D, are important in mitigating synaptogenesis, neurite and axonal outgrowth all of which have been shown to be aberrant in schizophrenia. U0126 cell line These data form important features of the experimental basis on which vitamin D has been implicated in the susceptibility to this disease. The environmental influence on susceptibility to schizophrenia has long been discussed, with hypovitaminosis D being a leading suspect. Epidemiological studies have repeatedly pointed to a season-of-birth effect in schizophrenia [91-96]. In northern latitudes, an excess number of births occur in the winter and early spring with a mirror effect occurring in the southern hemisphere – the magnitude of the effect on disease risk increasing

with distance from the equator. With regards to latitude, several studies have demonstrated increased incidence and prevalence of schizophrenia at higher latitudes in both hemispheres [97]. Interestingly, children of Afro-Caribbean, Black African, and Asian migrants to northern climates (such as the United Kingdom) have an increased risk of the disease compared with natives, adding further support of a possible contribution of vitamin D in the pathogenesis of the disease [98, 99]. The use of vitamin D supplementation Florfenicol in the gestational and/or perinatal period appears to reduce the risk of developing schizophrenia later in life [100, 101]. A recent study of serum neonatal 25(OH)D levels in a Danish population-based cohort implicated a role of neonatal 25(OH)D with later risk of developing schizophrenia. However, both low and high concentrations were associated with increased disease risk, findings that demand further interrogation [102]. There is a known heritable component in schizophrenia, with clustering being observed within families, especially in monozygotic twin pairs [103]. Monozygotic twins may be discordant for the disease suggesting gene-environment interactions.

The membrane was then incubated with rabbit polyclonal iNOS antibody (Sigma) followed by anti-rabbit immunoglobulin-horse radish peroxidase (Ig-HRP) conjugate (Sigma-Aldrich). Bound enzyme was detected by chemiluminescence following the manufacturer’s protocol (GE Healthcare, Piscataway, NJ). RAW 264·7 macrophages were seeded at a density of 5 × 106 per well in a six-well culture

plate and either left untreated or pretreated with PDTC for 1 hr, followed by stimulation with 5 μg of rRv2626c alone or with a combination of LPS and ΙFN-γ. Cells were harvested and nuclear extract was prepared from NP-40 lysed cells.36 Equal amounts of the protein extracts (50 μg) were fractionated on a 10% SDS-PAGE gel. The nuclear proteins were transferred onto a nitrocellulose membrane and incubated with polyclonal Selleckchem Obeticholic Acid rabbit antibody to NF-κB p50 or NF-κB p65 (Santa https://www.selleckchem.com/products/RO4929097.html Cruz Biotech, Santa Cruz, CA) followed by incubation with anti-rabbit Ig-HRP conjugate. Bound enzyme was detected by chemiluminescence (ECL). An equal amount of the nuclear extract (10 μg)

from each set (cells stimulated with rRv2626c, or rRv2626c + LPS or rRv2626c + IFN) was incubated at 37° for 30 min with 1 ng of γ-P32-radiolabelled consensus oligodeoxyribonucleotides containing the binding site for NF-κB (5′-ttgttacaagggactttccgctggggactttccagggaggcgtgg-3′; Santa Cruz Biotech) in a binding buffer [10 mm Tris, pH 7·5, 50 mm NaCl, 1 mm ethylenediaminetetraacetic acid (EDTA), 10% glycerol, 1 μg of poly dIdC, 1 mm dithiothreitol (DTT), 1 mm phenylmethylsulphonyl fluoride (PMSF) and 50 mm MgCl2]. For competition experiments, 100-fold molar excess of unlabelled consensus NF-κB or mutant NF-κB oligos was used to check the specificity of the DNA–protein complex. The DNA–protein complexes were resolved by electrophoresis on a 7% native PAGE gel at 3-mercaptopyruvate sulfurtransferase 4° in 1× Tris-borate-EDTA

(TBE). After electrophoresis, the gel was dried and exposed to Phosphor Imager screen (Fuji Film, Tokyo, Japan) at room temperature for 12 hr and the screen was scanned using the Typhoon system (GE Healthcare, Piscataway, NJ). Patients with TB who participated in this study were diagnosed at the Mahaveer Hospital and Research Centre, Hyderabad, India; their TB was confirmed by a tuberculin skin test, radiographic examination, and observation of acid-fast bacilli in sputum. Healthy controls were volunteers at the Centre for DNA Fingerprinting and Diagnostics who had no clinical symptoms of TB disease. Blood samples (2–3 ml) were collected from patients with TB (n = 48) as well as from healthy controls (n = 9), followed by separation of PBMCs on Ficoll-Histopaque (Sigma-Aldrich) as described previously.38 PBMCs were plated at a density of 2 × 105 per well in a 96-well culture plate and treated with rRv2626c (5 μg/ml) for 72 hr.

Lymphocyte encounters

with interendothelial junctions were determined by following the track of each lymphocyte on the videomicrographs over the characteristic phase-bright band between adjacent EC. In a second technique, lymphocytes were stained with CellTracker Orange according to the manufacturers instructions, then were made to interact with HUVEC monlayer in the parallel-plate flow chamber. After 10 min of shear stress application, the chamber was disassembled, and the cells were stained for VE-cadherin. To study diapedesis, the location of each lymphocyte relative to VE-cadherin staining was analyzed using a LSM 510 confocal microscope (Zeiss, Toronto, Ont., Canada) set to acquire images at 0.4 μm intervals in the z-plane. Lymphocytes were considered

to be associated Selleck Selumetinib with gap formation in the AJ if a break in endothelial VE-cadherin staining at least 2 μm wide was directly superimposed on the lymphocyte footprint. Lymphocytes were scored by blinded observer for the relationship in the z-plane to the VE-cadherin signal. To study the PECAM-1 enrichment around lymphocytes in the process of diapedesis, PECAM-1bright naïve T cells (CD45RA+) cells were depleted using CD45RA TAC (StemCell Technologies). The cells were stained with CellTracker Blue and were made to interact with the HUVEC monlayer in the parallel-plate flow chamber. After 10 min of shear stress application, the chamber was disassembled, and the cells were double stained for VE-cadherin and PECAM-1. Confluent HUVEC selleck kinase inhibitor monolayers seeded on Matrigel-coated AZD8055 research buy glass coverlips were treated with either DMSO or ND. Cells were fixed,

permeabilized, and blocked as described previously 46. The cells were then double-stained using anti-β-tubulin and anti-VE-cadherin primary and fluorophore-conjugated secondary antibodies. To determine MT and AJ morphology in cells treated with non-silencing or IQGAP1 RNAi, transfected HUVEC were trypsinized and seeded on coverslips at confluency. The monolayer was stained with either β-catenin or double-stained for MT and VE-cadherin. MT density adjacent to AJ was measured using image analysis software (OpenLab, Lexington, MA, USA). Regions of interest were defined extending 3 μm into the cell cortex from VE-cadherin-positive junctions to quantitate MT staining intensity in at least 30 cells in each experiment. To evaluate F-actin cytoskeleton changes, confluent HUVEC monolayers were fixed and permeabilized and F-actin was stained by FITC-phalloidin. To determine the effect of TNF-α treatment and shear stress on junction staining, HUVEC were treated with TNF-α and subjected to shear stress in conditions as described for TEM assay but with no lymphocytes. Then cells were fixed and permeabilized and stained for VE-cadherin, PECAM-1, and Jam-1. CD99 was stained without permeabilization.

ELISA experiments showed that TNF-α was not secreted by mock-infected cells or HB101-treated cells (Fig. 7E). These results were expected, because tnf-α mRNA was not detected by RT-PCR. However, E2348/69 infection activated TNF-α secretion at a high value (252 ± 8 ng/ml) at 2 h of infection, which decreased at 4 h post-infection (151 ± 13 ng/ml). In E22-infected cells, there was no decrease and TNF-α secretion was similar at 2 h (252 ± 8 ng/ml) and 4 h (247 ± 13 ng/ml) post-infection (Fig. 7E).

Therefore, as with E2348/69, E22 infection activates TNF-α synthesis and secretion. E22Δeae infection caused Selleck Cobimetinib contrary effects on TNF-α secretion depending on the infection time. At 2 h of E22Δeae infection, TNF-α secretion was of 282 ± 8 ng/ml, while at 4 h of infection, cells secreted 50% less TNF-α (126 ± 13 ng/ml) than cells infected with E22 WT (247 ± 13 ng/ml). TNF-α secretion in cells infected

with E22ΔescN CP-673451 price was not reduced (236 ± 8 ng/ml) at 2 h and decreased at 4 h (192 ± 13 ng/ml), whereas the secretion at 2 h in cells infected with E22ΔespA was 191 ± 8 ng/ml and at 4 h of 116 ± 13 ng/ml. Thus, T3SS is involved in the activation of TNF-α release. E22ΔfliC infection caused a reduced secretion of TNF-α at 2 h (201 ± 8 ng/ml), and at 4 h TNF-α was completely absent from the supernatants (Fig. 7F). Evidently, flagellin is a factor which is necessary to activate TNF-α secretion, and it is essential to maintain this cytokine in the supernatants of infected cells (strikingly similar is the effect of flagellin in IL-8 release). Inflammation induced by EPEC results from

the balance of positive and negative factors [39]. Here, we analysed the role of the EPEC virulence factors T3SS, EspA, intimin and flagellin, on the epithelial inflammatory response. MG-132 research buy The evaluation comprised TLR5 signalling activated by EPEC flagellin [25], activation of ERK1/2 [28] and NF-κB [27] pathways and transcription of proinflammatory cytokine genes [33, 39]. EPEC-induced cell signalling was reproduced and unified in an in vitro epithelial cell infection model, which consisted in using HT-29 cells infected with the prototype strain E2348/69 and the strain E22, which is a strain pathogenic for rabbits, which contains LEE but no BFP [40], and can be considered an atypical EPEC. The role of the virulence factors was studied using isogenic E22 mutants, to be able to corroborate the results in vivo through the experimental rabbit infection model [33]. The significance of EPEC flagellin in the activation of proinflammatory response is well established [25]. However, TLR5 expression, localization and functionality in intestinal epithelial cells have all been unclear [38], and previous studies have been focused on TLR5 distribution in polarized cells [41, 42].

In contrast, treatment with LGG wild-type results in an up-regulation of TLR-1, -2 and -4 compared to the dltD-treated group, highlighting the impact of inactivating the dltD gene. It is known that LTA molecules of certain bacteria can induce

proinflammatory signalling in macrophages by interaction with TLR-2 [56]. The exact role of d-alanylation in interaction of LTA with specific TLRs (TLR-2, TLR-6) and co-receptors (CD14, CD36) is not yet well established. Based on the crystal structure of TLR-2, the two acyl chains of LTA are suggested to interact with the lipid binding pocket of TLR-2, while the hydrophilic ALK inhibitor cancer glycerophosphate chain is thought to be exposed to solvent or to interact with TLR-6 or another co-receptor of TLR-2 [57–59]. However, as LTA is a major cell wall compound of lactobacilli, changing the structure

of LTA by removing d-alanine residues might as well effect the interactions with other surface molecules and therefore cause pleiotropic effects that can impact indirectly on the anti-inflammatory capacity of the lactobacilli. Nevertheless, our results with the dltD mutant compared to the wild-type probiotic strain are in line with those of the study by Grangette et al. [36], where a dltB mutant of L. plantarum NCIMB8826 also showed, compared to the wild-type strain, an enhanced anti-inflammatory capacity in vitro in monocytes and in a trinitrobenzene sulphonic acid (TNBS) colitis model [60]. selleck chemical Although both experimental set-ups (probiotic strains and colitis models) differ significantly, the study by Grangette et al. [36] and this study both suggest a key role for LTA modification in pro-/anti-inflammatory

effects of probiotic lactobacilli. Finally, the data from our experiments with LGG in the DSS-induced murine colitis model cannot be translated easily to the clinical setting, as introducing bacterial mutants in humans is not straightforward. However, it is interesting to mention that we also performed a pilot study with LGG in patients with active pouchitis (unpublished). MycoClean Mycoplasma Removal Kit Two patients with acute pouchitis received daily 1011 CFU/ml of LGG (Valio, Helsinki, Finland) in capsules for 4 weeks in a randomized cross-over trial (4 weeks probiotics, 4 weeks placebo). In one of the patients, the symptoms of active pouchitis seemed to be exacerbated by the treatment. This study was discontinued and we decided to focus upon animal models, such as presented in this report, to understand more clearly the interaction of LGG with the intestinal mucosa. The data from our experiments, together with reports from other research groups on animal models [28,29] and Crohn’s disease patients [61], underline that caution should be taken when applying the wild-type strain of the well-known probiotic LGG in patients with active IBD.

In thymocytes, signals from the TCR complex induce Nur77 and Nor-1 expression followed by translocation

from the nucleus to mitochondria. Nur77 and Nor-1 associate with Bcl-2 in the mitochondria, resulting in a conformation change that exposes the Bcl-2 BH3 domain, a presumed pro-apoptotic molecule of Bcl-2. As Nur77 and Nor-1 are heavily phosphorylated, we examined the requirement of Nur77 and Nor-1 phosphorylation in mitochondria translocation and Bcl-2 BH3 exposure. We found that HK434, a PKC agonist, in combination with calcium ionophore, can induce Nur77 and Nor-1 phosphorylation, translocation, Bcl-2 BH3 exposure and thymocyte apoptosis. Inhibitors of both classical and novel forms of PKC were able to block this process. In contrast, only the general but not classical PKC-specific NVP-BKM120 in vitro inhibitors were able to block the same process initiated by PMA, a commonly used PKC agonist. These data demonstrate a differential activation of PKC isoforms by PMA and HK434 in thymocytes, Sotrastaurin chemical structure and show the importance of PKC in mitochondria translocation of Nur77/Nor-1 and Bcl-2 conformation change during

TCR-induced thymocyte apoptosis. T-cell development is a dynamic process that involves the balance of apoptosis and proliferation 1–5. Early in development, DN (double negative CD4−CD8−) thymocytes that fail to express pre-TCR complex die through p53-dependent apoptosis. Those that express pre-TCR proliferate and differentiate into DP (double positive CD4+CD8+) thymocytes. DP thymocytes are exquisitely sensitive to apoptosis and survive for only a few days. DP thymocytes that are autoreactive to ubiquitously expressed self-antigen die immediately in not a process called negative selection 3. Only a few DP thymocytes differentiate into SP (single positive CD4+CD8− or CD4−CD8+) cells. Some of these SP cells (semi-mature SP cells) are still subject to negative selection. Those that are reactive to “tissue-specific” antigens expressed under the control of AIRE in medullary thymic

epithelial cells die through apoptosis 6. AIRE deficiency results in the escape of autoreactive semi-mature SP cells, leading to multi-organ autoimmunity. The signal transduction pathways of negative selection are poorly understood although many genes have been implicated, including the Nur77 family of transcription factors and their regulators (e.g. MEK5, HDAC7) 7–9, Bim (and its downstream proteins Bak and Bax) 10, 11, PTEN, a lipid phosphatase 12, E2F1 cell cycle protein 13 and members of the MAP kinase family 4. As members of the orphan steroid receptor, Nur77 and its family member, Nor-1, are transcription factors that are active without addition of any known ligands 14. Nur77 and Nor-1 expression is induced by TCR signaling. Expression of a dominant negative Nur77 protein can inhibit negative selection 15, 16.

The mortality risk was equal in the two groups by day 106 of follow-up, and improved in the transplanted group thereafter. McDonald and Russ have reported similar findings using ANZDATA.14 An analysis of the period 1991–2000 found an 80% lower long-term risk of mortality between those transplanted and those remaining on the waiting list. Cameron et al. have performed a meta-analysis examining

the effect of transplantation on overall quality of life.15 Successful kidney transplantation was associated with improved Inhibitor Library research buy general wellbeing and less distress, when compared with continued haemodialysis or peritoneal dialysis. There are several individual studies that have examined quality of life issues in more detail. Evans et al. reported that 79.1% of transplant recipients describe near normal physical function, compared with only 50% of dialysis patients.16 Mental function scores were also higher in transplant recipients. Studies by both Gorlen et al.17 and Laupacis et al.18 found that the quality of life improvements associated with transplantation were sustained long term. However, transplantation continued to affect quality of life relative to normal.18 This was attributed to the side effects of immunosuppression,

comorbid conditions and the stress associated with the possibility of losing graft function. A detailed analysis of the relative costs of Mannose-binding protein-associated serine protease dialysis and Selleck Wnt inhibitor transplantation has been performed by Kidney Health Australia.19 Estimates of the cost of home or satellite-based dialysis (haemodialysis and peritoneal) for an individual are approximately $45 000–$60 000 per year. Hospital-based haemodialysis is estimated to cost approximately $83 000 per year. Although the initial cost of transplanting an individual is estimated to be relatively high ($62 000 for the first year) the cost falls significantly thereafter (approximately $11 000 per year for year 2 and onwards). The estimated costs associated

with an individual live donor transplant are similar to those for an individual deceased donor transplant.19 A Canadian report estimated that transplanting an individual would result in savings of CAN$104 000 over a 20-year period.20 Only a brief account of the overall safety data will be summarized here. A much more detailed analysis of the literature regarding donor safety will follow in subsequent sections of these Living Kidney Donor guidelines. By and large, live kidney donation is considered to be safe for the majority of healthy donors. This contention, however, is based predominantly on large retrospective studies, which demonstrate that unilateral nephrectomy in healthy subjects is generally associated with a very low level of long-term risk.21–27 A meta-analysis published by Garg et al. has examined the development of proteinuria in donors.
