OBJECTIVES To analyze association of different HLA genotypes for predisposition to type-I autoimmune hepatitis in Western India. METHODS This study was undertaken on patients of type-I autoimmune hepatitis (defined by international criteria by IAHG, 1999). HLA genotyping for class I and II was done in 20 patients of autoimmune hepatitis and 100 healthy controls. Statistics were done using Hal...
Large consortia efforts and genome-wide association studies (GWASs) have linked a number of genetic variants within the 6p21 chromosomal region to non-Hodgkin lymphoma (NHL). Complementing these efforts, we genotyped previously reported SNPs in the human leukocyte antigen (HLA) class I (rs6457327) and class II (rs9271100, rs2647012 and rs10484561) regions in a total of 1,145 subjects (567 NHL c...
It was demonstrated previously that a peptide derived from a conserved region of MHC class II, HLA-DQA1, inhibits proliferation of allogeneic T cells in vitro. Administration of HLA-DQA1 in conjunction with allogeneic cells at the time of priming or at the time of rechallenge prevented the development of the delayed type hypersensitivity response in vivo. The immunomodulatory effects of HLA-DQA...
Anti-dengue T-cell responses have been implicated in both protection and immunopathology. However, most of the T-cell studies for dengue include few epitopes, with limited knowledge of their inter-serotype variation and the breadth of their human leukocyte antigen (HLA) affinity. In order to expand our knowledge of HLA-restricted dengue epitopes, we screened T-cell responses against 477 overlap...

recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...
Human leukocyte antigen (HLA) genes have been associated with susceptibility and protection against a number of cancers. Here we used an immunogenetic epidemiological approach to evaluate the overall influence 127 HLA Class I II alleles on 30 types cancer. We found preponderance protective (negatively correlated cancer prevalences), especially for I. Of cancers investigated, 13 were mostly effe...
OBJECTIVE To study HLA class I and class II association in Tunisian patients with reactive (ReA) and undifferentiated arthritis (UA). METHODS The study included 17 patients with ReA defined according to the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA), 11 patients classified as having undifferentiated arthritis and 100 unrelated healthy controls. HLA class I a...
Despite multidisciplinary local and systemic therapeutic approaches, the prognosis for most patients with brain metastases is still dismal. The role of adaptive and innate anti-tumor response including the Human Leukocyte Antigen (HLA) machinery of antigen presentation is still unclear. We present data on the HLA class II-chaperone molecule CD74 in brain metastases and its impact on the HLA pep...
BACKGROUND The HLA class II molecules play a central role in the generation of human immunodeficiency virus (HIV)-specific CD4(+) T-helper cells, which are critical for the induction of cytotoxic CD8(+) T cell responses. However, little is known about the impact of HLA class II alleles on HIV disease progression. METHODS In this study we investigated the effect of HLA class II alleles on HIV ...
