results demonstrate that HIV-1 Nef's inferior ability to downregulate MHC-B compared to that of MHC-A is conserved across primate lentiviruses and suggest that this property influences antiviral cellular immune responses.
Data (from studies using TCR-F50/GIL (显示 AQP3 ELISA试剂盒)/HLA-A2) suggest there are multiple solutions to recognizing identical peptide-MHC (显示 HLAE ELISA试剂盒) ligand with sufficient affinity to elicit broad anti- influenza virus response protective against viral escape. (TCR-F50 = GIL (显示 AQP3 ELISA试剂盒)-specific T-cell receptor, alpha-beta; HLA-A2 major histocompatibility complex class I A; GIL (显示 AQP3 ELISA试剂盒) = immunodominant influenza A virus epitope from M1) [M1, matrix protein 1]
In the present study, the HLA-A*31:01 allele was identified as a risk allele of lamotrigine-induced severe cutaneous adverse reactions in Koreans
Three new HLA class I alleles, HLA-A*02:620, HLA-B*27:150 and HLA-B*07:05:01:02, were described in the Spanish Caucasoid population
Data suggest that KH1 (显示 KCNF1 ELISA试剂盒) and HK2 (显示 HK2 ELISA试剂盒) domains of MEX3C (显示 MEX3C ELISA试剂盒) bind with high affinity to MRE10, a 10-mer (显示 MERTK ELISA试剂盒) RNA (5prime-CAGAGUUUAG-3prime) containing an eight-nucleotide MEX3C (显示 MEX3C ELISA试剂盒) recognition element motif (AGAGUUUA); 3prime-untranslated region of HLA-A2 mRNA contains such a high affinity binding site for KH domains of MEX3C (显示 MEX3C ELISA试剂盒). (MEX3C (显示 MEX3C ELISA试剂盒) = mex-3 RNA binding family member C; HLA-A2 = HLA class I (显示 MICA ELISA试剂盒) histocompatibility antigen, A-2 alpha chain (显示 FCGRT ELISA试剂盒))
this study shows that alpha3-deletion isoform of HLA-A11 plays role in the immune escape of HIV-1
Data suggest that personalized peptide vaccine (PPV (显示 PPP6C ELISA试剂盒)) with these nine CTL epitope peptides exhibit a good safety profile and positive immunological responses in HLA-A11+ or -A33 (显示 GPA33 ELISA试剂盒)+ cancer patients.
findings demonstrate that gliadins contain epitopes that elicit CD8 (显示 CD8A ELISA试剂盒)+ T cell responses restricted by HLA class I (显示 MICA ELISA试剂盒) A*0101 and B*0801 molecules
Data suggest that only a small fraction of HLA-A*02:01- (HA)-binding ESO peptides are immunogenic, namely those that have high peptide-binding strength and peptide/HA complex stability. This study involved comparison of in silico-predicted and observed cytotoxic T-lymphocyte recognition of tumor antigen epitopes in melanoma patients and transgenic/knockout mice. (ESO = tumor antigen NY-ESO-1 (显示 CTAG1B ELISA试剂盒))
The safety, the overall survival (OS), and the immunological responses based on an ELISPOT assay were determined to assess differences in patients who were HLA-A24 (显示 CD164 ELISA试剂盒)-positive [24(+)] and HLA-A24 (显示 CD164 ELISA试剂盒)-negative [24(-)].
HLA-A belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. They are expressed in nearly all cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the alpha1 and alpha2 domains, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exons 6 and 7 encode the cytoplasmic tail. Polymorphisms within exon 2 and exon 3 are responsible for the peptide binding specificity of each class one molecule. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. Hundreds of HLA-A alleles have been described.
