Human histocompatibility leukocyte antigen (HLA)-DM is a facilitator of antigen presentation via major histocompatibility complex (MHC) class II molecules. In the absence of HLA-DM, MHC class II molecules do not present natural peptides, but tend to remain associated with class II-associated invariant chain peptides (CLIP). Recently, DM was shown to catalyze the release of CLIP from HLA-DR. We ...

Humanized mice expressing Human Leukocyte Antigen (HLA) class I or II transgenes have been generated, but the role of class I vs class II on human T and B cell reconstitution and function has not been investigated in detail. Herein we show that NRG (NOD.RagKO.IL2RγcKO) mice expressing HLA-DR4 molecules (DRAG mice) and those co-expressing HLA-DR4 and HLA-A2 molecules (DRAGA mice) did not differ ...

Background The extreme variability at the Killer cell Immunoglobulin like Receptor (KIR) expressed on the surface of natural killer cells interacts with Human Leukocyte Antigen (HLA) Class I appear to play a crucial role in the outcome against viral infection. The combination of HLA/KIR gene products either individually or collectively have been implicated in the control of HIV-1 in various pop...

A 35-year-old Korean man with a 10-year history of ulcerative colitis (UC) presented with pain and swelling of the right neck. The patient was diagnosed with Takayasu's arteritis (TA) and had human leukocyte antigen (HLA) B-52, which is frequently found in patients having both UC and Takayasu's disease concurrently on HLA analysis. This case is the first report of a patient with both TA and UC ...

Background Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the involvement of multiple organs and autoantibody production. This study aimed to determine association human leukocyte antigen (HLA)-DQ -DR alleles with SLE at tertiary hospital in Bangladesh. Methods case–control was conducted Department Rheumatology, Bangabandhu Sheikh Mujib Medical University (...

Promiscuous human leukocyte antigen (HLA) binding peptides are ideal targets for vaccine development. Existing computational models for prediction of promiscuous peptides used hidden Markov models and artificial neural networks as prediction algorithms. We report a system based on support vector machines that outperforms previously published methods. Preliminary testing showed that it can predi...

Immunosurveillance is an extrinsic mechanism of cancer suppression that eliminates nascent tumors. However, the selection imposed by immunosurveillance can drive tumor evolution and the emergence of clinically apparent neoplasms. Mechanisms of immune escape acquired by less immunogenic variants during this process, termed immunoediting, may contribute significantly to malignant progression. In ...
