Abstract
BACKGROUND The glycan moieties sialyl-Lewis-X and/or -A (sLeX/A) are the primary ligands for E-selectin, regulating subsequent tumor cell extravasation into distant organs. However, the nature of the glycoprotein scaffolds displaying these glycans in breast cancer remains unclear and constitutes the focus of the present investigation. METHODS We isolated glycoproteins that bind E-selectin from the CF1_T breast cancer cell line, derived from a patient with ductal carcinoma. Proteins were identified using bottom-up proteomics approach by nanoLC-orbitrap LTQ-MS/MS. Data were curated using bioinformatics tools to highlight clinically relevant glycoproteins, which were validated by flow cytometry, Western blot, immunohistochemistry and in-situ proximity ligation assays in clinical samples. RESULTS We observed that the CF1_T cell line expressed sLeX, but not sLeA and the E-selectin reactivity was mainly on N-glycans. MS and bioinformatics analysis of the targeted glycoproteins, when narrowed down to the most clinically relevant species in breast cancer, identified CD44 glycoprotein (HCELL) and CD13 as key E-selectin ligands. Additionally, the co-expression of sLeX-CD44 and sLeX-CD13 was confirmed in clinical breast cancer tissue samples. CONCLUSIONS Both CD44 and CD13 glycoforms display sLeX in breast cancer and bind E-selectin, suggesting a key role in metastasis development. Such observations provide a novel molecular rationale for developing targeted therapeutics. GENERAL SIGNIFICANCE While HCELL expression in breast cancer has been previously reported, this is the first study indicating that CD13 functions as an E-selectin ligand in breast cancer. This observation supports previous associations of CD13 with metastasis and draws attention to this glycoprotein as an anti-cancer target.

Abstract
Kupffer cells (KC) are the liver macrophage population that resides in the hepatic sinusoids and efficiently phagocyte pathogens by establishing an intimate contact with circulating blood. KC constitute the liver host cells in Leishmania infection, nevertheless little is described about their role, apart from their notable contribution in granulomatous inflammation. The present study aims to investigate how canine KC sense and react to the presence of Leishmania infantum promastigotes and amastigotes by evaluating the gene expression of specific innate immune cell receptors and cytokines, as well as the induction of nitric oxide and urea production. Complementarily, the impact of a leishmanicidal drug - meglumine antimoniate (MgA) - in infected KC was also explored. KC revealed to be susceptible to both parasite forms and no major differences were found in the immune response generated. L. infantum parasites seem to interact with KC innate immune receptors and induce an anergic state, promoting immune tolerance and parasite survival. The addition of MgA to infected KC breaks the parasite imposed silence and increased gene expression of Toll-like receptors (TLR) 2 and TLR4, possibly activating downstream pathways. Understanding how KC sense and react to parasite presence could bring new insights into the control or even elimination of canine leishmaniasis.

Abstract
The diversity of killer-cell immunoglobulin-like receptors (KIR) genes was evaluated in Portuguese and the observed genotypic profiles were found related to the ones reported in European populations. The KIR repertoire after hematopoietic stem cell transplantation is determined by these gene frequencies and the KIR group B motifs are the less common. We estimated donor-KIR/recipient-ligand interactions in transplants with related donors and unrelated donors found in a local registry or from abroad. A large fraction of transplants had all three ligands of inhibitory receptors, and therefore, in theory were not prone to natural killer cell (NK) mediated alloreactivity. Furthermore, the distribution of KIR alloreactive interactions was found independent of the donor-recipient genetic proximity, probably because of different gene segregation and comparable KIR frequencies in the donor pools.

Abstract
INTRODUCTION This study aims to compare the molecular gene expression during ischemia reperfusion injury. Several surgical times were considered: in the beginning of the harvesting (T0), at the end of the cold ischemia period (T1), and after reperfusion (T2) and compared with graft dysfunction after liver transplant (OLT). METHODS We studied 54 patients undergoing OLT. Clinical, laboratory data, and histologic data (Suzuki classification) as well as the Survival Outcomes Following Liver Transplantation (SOFT) score were used and compared with the molecular gene expression of the following genes: Interleukin (IL)-1b, IL-6, tumor necrosis factor-α, perforin, E-selectin (SELE), Fas-ligand, granzyme B, heme oxygenase-1, and nitric oxide synthetase. RESULTS Fifteen patients presented with graft dysfunction according to SOFT criteria. No relevant data were obtained by comparing the variables graft dysfunction and histologic variables. We observed a statistically significant relation between SELE at T0 (P = .013) and IL-1β at T0 (P = .028) and early graft dysfunction. CONCLUSIONS We conclude that several genetically determined proinflammatory expressions may play a critical role in the development of graft dysfunction after OLT.

Abstract
Human leukocyte antigen (HLA)-B27 is the mostly known major histocompatibility complex (MHC) gene associated with ankylosing spondylitis (AS). Nonetheless, there is substantial evidence that other MHC genes appear to be associated with the disease, although it has not yet been established whether these associations are driven by direct associations or by linkage disequilibrium (LD) mechanisms. We aimed to investigate the contributions of HLA class I and II alleles and B27-haplotypes for AS in a case-control study. A total of 188 HLA-B27 AS cases and 189 HLA-B27 healthy controls were selected and typed for HLA class I and II by the Luminex polymerase chain reaction-sequence specific oligonucleotide probe (PCR-SSOP) method. Allelic and haplotypic distributions were estimated by maximum likelihood method using Arlequin v3.11 and statistical analysis were performed by Stata10.1. No associations were found between non-HLA-B27 loci and AS susceptibility, but several associations were observed for phenotypic features of the disease. DRB1*08 was identified as a risk factor for uveitis and DQB1*04 seems to provide protection for AS severity (functional, metrological and radiological indexes). A*02/B27/C*02/DRB1*01/DQB1*05 [P<0.0001; odds ratio (OR) = 39.06; 95% confidence interval (CI) (2.34-651)] is the only haplotype that seems to confer susceptibility to AS. Moreover, the haplotype A*02/B27/C*01/DRB1*08/DQB1*04 seems to provide protection for disease functional and radiological repercussions. Our findings are compatible with the hypothesis that other genes within the HLA region besides HLA-B27 might play some role in AS susceptibility and severity.

Abstract
The Zucker diabetic fatty (ZDF) rat is an obesity and type 2 diabetes model. Progression to diabetes is well characterised in ZDF rats, but only in the fasted state. We evaluated the mechanisms underlying postprandial insulin resistance in young ZDF rats. We tested the hypothesis that the overall postprandial action of insulin is affected in ZDF rats as a result of impairment of the hepatic parasympathetic-nitric oxide (PSN-NO) axis and/or glutathione (GSH), resulting in decreased indirect (PSN-NO axis) and direct actions of insulin. Nine-week-old male ZDF rats and lean Zucker rats (LZR, controls) were used. The action of insulin was assessed in the fed state before and after parasympathetic antagonism atropine. Basal hepatic NO and GSH were measured, as well as NO synthase (NOS) and γ-glutamyl-cysteine synthethase (GCS) activity and expression. ZDF rats presented postprandial hyperglycaemia (ZDF, 201.4 ± 12.9 mg/dl; LZR, 107.7 ± 4.3 mg/dl), but not insulinopaenia (ZDF, 5.9 ± 0.8 ng/ml; LZR, 1.5 ± 0.3 ng/ml). Total postprandial insulin resistance was observed (ZDF, 78.6 ± 7.5 mg glucose/kg; LZR, 289.2 ± 24.7 mg glucose/kg), with a decrease in both the direct action of insulin (ZDF, 54.8 ± 7.0 mg glucose/kg; LZR, 173.3 ± 20.5 mg glucose/kg) and the PSN-NO axis (ZDF, 24.5 ± 3.9 mg glucose/kg; LZR, 115.9 ± 19.4 mg glucose/kg). Hepatic NO (ZDF, 117.2 ± 11.4 μmol/g tissue; LZR, 164.6 ± 4.9 μmol/g tissue) and GSH (ZDF, 4.9 ± 0.3 μmol/g; LZR, 5.9 ± 0.2 μmol/g) were also compromised as a result of decreased NOS and GCS activity, respectively. These results suggest a compromise of the mechanism responsible for potentiating insulin action after a meal in ZDF rats. We show that defective PSN-NO axis and GSH synthesis, together with an impaired direct action of insulin, appears to contribute to postprandial insulin resistance in this model.

Abstract
HLA-NET (a European COST Action) aims at networking researchers working in bone marrow transplantation, epidemiology and population genetics to improve the molecular characterization of the HLA genetic diversity of human populations, with an expected strong impact on both public health and fundamental research. Such improvements involve finding consensual strategies to characterize human populations and samples and report HLA molecular typings and ambiguities; proposing user-friendly access to databases and computer tools and defining minimal requirements related to ethical aspects. The overall outcome is the provision of population genetic characterizations and comparisons in a standard way by all interested laboratories. This article reports the recommendations of four working groups (WG1-4) of the HLA-NET network at the mid-term of its activities. WG1 (Population definitions and sampling strategies for population genetics’ analyses) recommends avoiding outdated racial classifications and population names (e.g. ‘Caucasian’) and using instead geographic and/or cultural (e.g. linguistic) criteria to describe human populations (e.g. ‘pan-European’). A standard ‘HLA-NET POPULATION DATA QUESTIONNAIRE’ has been finalized and is available for the whole HLA community. WG2 (HLA typing standards for population genetics analyses) recommends retaining maximal information when reporting HLA typing results. Rather than using the National Marrow Donor Program coding system, all ambiguities should be provided by listing all allele pairs required to explain each genotype, according to the formats proposed in ‘HLA-NET GUIDELINES FOR REPORTING HLA TYPINGS’. The group also suggests taking into account a preliminary list of alleles defined by polymorphisms outside the peptide-binding sites that may affect population genetic statistics because of significant frequencies. WG3 (Bioinformatic strategies for HLA population data storage and analysis) recommends the use of programs capable of dealing with ambiguous data, such as the ‘gene[rate]’ computer tools to estimate frequencies, test for Hardy–Weinberg equilibrium and selective neutrality on data containing any number and kind of ambiguities. WG4 (Ethical issues) proposes to adopt thorough general principles for any HLA population study to ensure that it conforms to (inter)national legislation or recommendations/guidelines. All HLA-NET guidelines and tools are available through its website http://hla-net.eu.

Abstract
OBJECTIVE Association between ankylosing spondylitis (AS) and two genes, ERAP1 and IL23R, has recently been reported in North American and British populations. The population attributable risk fraction for ERAP1 in this study was 25%, and for IL23R, 9%. Confirmation of these findings to ERAP1 in other ethnic groups has not yet been demonstrated. We sought to test the association between single nucleotide polymorphisms (SNPs) in these genes and susceptibility to AS among a Portuguese population. We also investigated the role of these genes in clinical manifestations of AS, including age of symptom onset, the Bath Ankylosing Spondylitis Disease Activity, Metrology and Functional Indices, and the modified Stoke Ankylosing Spondylitis Spinal Score. METHODS The study was conducted on 358 AS cases and 285 ethnically matched Portuguese healthy controls. AS was defined according to the modified New York Criteria. Genotyping of IL23R and ERAP1 allelic variants was carried out with TaqMan allelic discrimination assays. Association analysis was performed using the Cochrane-Armitage and linear regression tests of genotypes as implemented in PLINK for dichotomous and quantitative variables respectively. A meta-analysis for Portuguese and previously published Spanish IL23R data was performed using the StatsDirect Statistical tools, by fixed and random effects models. RESULTS A total of 14 nsSNPs markers (8 for IL23R, 5 for ERAP1, 1 for LN-PEP) were analysed. Three markers (2 for IL23R and 1 for ERAP1) showed significant single-locus disease associations, confirming that the association of these genes with AS in the Portuguese population. The strongest associated SNP in IL23R was rs1004819 (OR=1.4, p=0.0049), and in ERAP1 was rs30187 (OR=1.26, p=0.035). The population attributable risk fractions in the Portuguese population for these SNPs are 11% and 9.7% respectively. No association was seen with any SNP in LN-PEP, which flanks ERAP1 and was associated with AS in the British population. No association was seen with clinical manifestations of AS. CONCLUSION These results show that IL23R and ERAP1 genes are also associated with susceptibility to AS in the Portuguese population, and that they contribute a significant proportion of the population risk for this disease.

Abstract
Ankylosing spondylitis (AS) is a common rheumatic condition, highly heritable. Much of the genetic contribution to the disease lies in the major histocompatibility complex (MHC). The association with the allele group HLA-B*27 has been described worldwide for 30 years. On the other hand, genome wide scans have provided some interesting results showing that other MHC and non-MHC genes could be implicated either in disease susceptibility and phenotypic manifestations. Different hypothesis for disease pathophysiology have been investigated which contribute for a better understanding of the genetic basis of AS. This review aims to summarize the status of the knowledge in this exciting area. New data may, in a near future, change the screening of patients and generate new insights for the emergence of novel therapies.

Abstract
5081 Background: Gene polymorphisms in key immunoregulatory molecules may contribute to the heterogeneity in outcome between individuals with bladder superficial carcinome receiving the immunotherapeutic treatment with BCG. This study aims to verify and identify cytokine gene polymorphisms that could influence the immune response to BCG and antitumoural action in those patients. Methods: We studied 90 patients, after turb and BCG intravesical, there where 72 responders (80 %), 18 non-responders (20%) all patients are multiple or recurrent except T1 G3 or Cis, the median follow up is 4,5 years The cytokines single nucleotide polymorphisms (SNP’s) (IL-1a (-889T/C), IL-1β (-511C/T), IL-1β (3962T/C), IL-1R (970 C/T), IL-1Ra (11100 T/C), IL-4 (-590 C/T), IL4-Ra (+576 G/A), IL-6 (-174 G/C), IL-10 (-1082GA/-819CT/-592CA), IL-12p35 (-916C/T), TGF-β (Codon 10 C/T), TNF-a (488GA/-238GA/-308GA), TNF-β (252 G/A), IFN-γ (+874 T/A)) genotypes were assessed by PCR with Sequence Specific Primers (PCR-SSP). Genotypes and allele frequencies of responders and non-responders (with tumour recidive) to the treatment were compared and evaluated by the two-sided Fisher’s exact test or Chi square and odds ratios (OR) were calculated as an estimate of relative risk. Results: It was found a correlation of cytokine gene polymorphisms to outcome of patients for both the genotype and haplotype TNF-a 488G/-238G/-308G frequencies, which are significantly higher in patients with tumour recidive after BCG treatment (non-responders 72,2% vs responders 42% OR=3,6; 95%CI 1.15 to 11.17 p=0.033). From the other genes studied, we could depict a weak association of the IL-1R 970 T/T genotype, with a higher frequency in non-responder patients (27,8% vs 4.2% in responders, p<0.05) and with IL-10 -1082 A allele also more frequent in non-responders to BCG (75% vs 54,8%; p<0.05). Conclusions: These results suggest that host genetics of immune regulatory molecules may play a role in predicting the antitumoural response after BCG treatment of bladder cancer. Confirmation of these findings in other populations is required. No significant financial relationships to disclose.

Abstract
OBJECTIVE To clarify the influence of the HLA-DRB1 locus on the susceptibility to rheumatoid arthritis and the production of anti-cyclic citrullinated peptide antibodies (anti-CCP) in a Portuguese population. METHODS 141 patients with rheumatoid arthritis fulfilling the American College of Rheumatology 1987 revised criteria for rheumatoid arthritis were compared with 150 healthy controls. Human leucocyte antigen (HLA)-DRB1 locus genotyping was assessed by polymerase chain reaction reverse probing assays and sequence-specific primers. Anti-CCP antibodies were quantified by ELISA in patients with rheumatoid arthritis. Frequencies between groups were compared by the two-sided Fisher's exact test and considered significant if p<0.05. RESULTS The HLA-DRB1*04 and HLA-DRB1*10 groups were highly associated with rheumatoid arthritis (p<0.001 and p = 0.031, respectively). High titres of anti-CCP antibodies were largely associated with the presence of HLA-DRB1*04/10. CONCLUSION The well-recognised susceptibility alleles to rheumatoid arthritis, HLA-DRB1*04, were associated with rheumatoid arthritis in Portuguese patients. The relatively rare DRB1*10 was also associated with rheumatoid arthritis, as was described previously in other southern European countries. Both groups were associated with high anti-CCP titres, reinforcing its relevance to disease onset.

Abstract
We investigated whether a novel chemotherapy-alone conditioning regimen would permit durable engraftment of standard doses of CD34+ purified stem cell grafts from full-haplotype mismatched related donors. We also examined the role of infusing limited doses of donor leukocytes for prevention of leukemia relapse. Our conditioning regimen consisted of thiotepa, fludarabine, rabbit antithymocyte globulin, melphalan, cyclosporin, and prednisolone. Since October 1998, 14 patients with high-risk leukemia were treated; 13 donor-patient pairs shared 3 of 6 HLA antigens, and 1 pair shared 5 of 6 HLA antigens. A median of 5.4 x 10(6) CD34+ cells per kilogram, 1.62 x 10(4) CD3+ cells per kilogram, and 9.32 x 10(4) CD19+ cells per kilogram were infused. T-cell depletion was the only graft-versus-host disease (GVHD) prophylaxis. All patients had prompt engraftment, and no late graft rejections were observed. All surviving patients received at least 1 infusion of donor whole blood containing 5, 7, 10, 25, or 50 x 10(3) CD3+ cells per kilogram between days 25 and 95 after transplantation, after which 8 developed acute GVHD (3 grade I, 2 grade II, 2 grade III, and 1 grade IV) and 2 developed a bronchiolitis obliterans-like syndrome. After attaining complete remission, 5 patients relapsed and died with active leukemia. The estimated relapse-related mortality at 4 years is 38.1%. As of June 15, 2003, 6 of 14 patients have survived a median of 43.5 months after transplantation with 100% donor cells. All 6 surviving patients developed acute GVHD and had a natural killer cell mismatch with their donors in the direction of graft versus host. The estimated overall survival and event-free survival for the 14 patients at 4 years is 41.7% +/- 13.5%.

Abstract
Allelic differences in gene promoter or codifying regions have been described to affect regulation of gene expression, consequently increasing or decreasing cytokine production and signal transduction responses to a given stimulus. This observation has been reported for interleukin (IL)-10 (-1082 A/G; -819/-592 CT/CA), transforming growth factor (TGF)-beta (codon 10 C/T, codon 25 G/C), tumor necrosis factor (TNF)-alpha (-308 G/A), TNF-beta (+252 A/G), interferon (IFN)-gamma (+874 T/A), IL-6 (-174 G/C), and IL-4R alpha (+1902 G/A). To evaluate the influence of these cytokine genotypes on the development of acute or chronic rejection, we correlated the genotypes of both kidney graft recipients and cadaver donors with the clinical outcome. Kidney recipients had 5 years follow-up, at least 2 HLA-DRB compatibilities, and a maximum of 25% anti-HLA pretransplantation sensitization. The clinical outcomes were grouped as follows: stable functioning graft (NR, n = 35); acute rejection episodes (AR, n = 31); and chronic rejection (CR, n = 31). The cytokine genotype polymorphisms were defined using PCR-SSP typing. A statistical analysis showed a significant prevalence of recipient IL-10 -819/-592 genotype among CR individuals; whereas among donors, the TGF-beta codon 10 CT genotype was significantly associated with the AR cohort and the IL-6 -174 CC genotype with CR. Other albeit not significant observations included a strong predisposition of recipient TGF-beta codon 10 CT genotype with CR, and TNF-beta 252 AA with AR. A low frequency of TNF-alpha -308 AA genotype also was observed among recipients and donors who showed poor allograft outcomes.
