JO - HLA VL - 101 IS - 1 SN - 0001-2815 CY - Oxford PB - Wiley M1 - DKFZ-2022-02455 SP - 24-33 PY - 2023 N1 - #EA:F210#LA:F210# / 2023 Jan;101(1):24-33 AB - The human leukocyte antigen (HLA) system represents a central component of the antigen presentation machinery. As every patient possesses a defined set of HLA molecules, only certain antigens can be presented on the cell surface. Thus, studying HLA type-dependent antigen presentation can improve the understanding of variation in susceptibility to various diseases, including infectious diseases and cancer. In archival formalin-fixed paraffin-embedded (FFPE) tissue, the HLA type is difficult to analyze due to fragmentation of DNA, hindering the application of commonly used assays that rely on long DNA stretches. Addressing these difficulties, we present a refined approach for characterizing presence or absence of HLA-A*02, the most common HLA-A allele in the Caucasian population, in archival samples. We validated our genotyping strategy in a cohort of 90 samples with HLA status obtained by an NGS-based method. 90 KW - Cancer immunoediting (Other) KW - Formalin-fixed paraffin-embedded tissue samples (Other) KW - HLA typing (Other) KW - MSI cancer (Other) LB - PUB:(DE-HGF)16 C6 - pmid:36251018 DO - DOI:10.1111/tan.14846 UR - https://inrepo02.dkfz.de/record/182138 ER -
