To date, no clear understanding of HLA-E expression has been elucidated and previous work had shown that HLA-E was expressed intracellularly but was not expressed on the surface of the class I deficient cell line .221. In order to gain insight into the signals controlling surface expression ...
Using ELISA, flow cytometry, immunoprecipitation, mass spectrometry, Western blot and immunohistochemistry, we found that the target antigens recognised by the two novel mAbs KU44.22B and KU44.13A, are integrin α3 and CD26 respectively, with high levels of expression in human pancreatic and other...

recognition. Binding of a restricted set of peptides derived from other Class I leader sequences to the HLA-E and B2M (beta2 microglobulin) complex leads to interaction with NKG2A on NK cells. This binding protects the HLA-G-expressing cell from NK cell killing. HLA-E expression is ...
(5 μg/L) and the HLA expression was analyzed 24,48,72,96 and 120 h after treatment.RT-PCR was used to evaluate HLA-G and HLA-E expression at mRNA level in human fetal MSCs.Results: Flow cytometry results showed that fetal MSCs expressed high level of HLA class Ⅰ(HLA-Ⅰ) antigen...
图10. HLA LOH协同TMB(D/E)和PD-L1(F/G)对ICI治疗的预测 除了在免疫治疗指导之外,HLA LOH也被证明是肿瘤进化的早期事件,例如,伦敦大学癌症研究所2017年发表在Cell上的研究证实[11],约40%的早期非小细胞肺癌患者会发生HLA LOH,而在TRA...
Elevated HLA-E levels in human glioblastomas but not in grade I to III astrocytomas correlate with infiltrating CD8+ cells HLA-E is a ligand for the immune-inhibitory NKG2A receptor expressed on NK and T cells. To investigate HLA-E expression and immune cell infiltration in hum... M Mitte...
[8] NEGRAO M V,LAM V K,REUBEN A,et al. PD-L1 Expression,tumor mutational burden,and cancer gene mutations are stronger predictors of benefit from immune checkpoint blockade than HLA class Ⅰ genotype in non-small cell lung cancer[J]. J Thorac Oncol,2019,14(6):1021-1031. DOI:10. 1016...
In order to ablate the expression of HLA-I and HLA-II on the cell surface, we attempted to target genes encoding β2-microglobulin (B2M) and α chains of HLA-II molecules with the CRISPR/Cas9 gene editing system. We employed web-based gRNA designing tools such as CHOPCHOP20, E-CRISP21...
Increased expression of activation antigens on CD8+ T lymphocytes in Myalgic Encephalomyelitis/chronic fatigue syndrome: inverse associations with lowered ... There is now evidence that specific subgroups of patients with Myalgic Encephalomyelitis / chronic fatigue syndrome (ME/CFS) suffer from a neuro-...
