Project description:HLA-C expresion varies widely across the different HLA-C alleles. MicroRNA binding can partly explain the differences in HLA-C allele expression however other contributing factors still remain undetermined. Here we use two common HLA-C alleles, HLA-C*05:01 and HLA-C*07:02, to explore differences in expression levels. Using functional, structural and peptide repertoire comparisons we demonstrate that HLA-C expression levels are not only modulated at the RNA level but also at the protein level. This dataset contains RAW data and database search results for HLA-C*05:01 and HLA-C*07:02 from the 721.221 cell line.
Project description:Analysis of SCC-15 tongue cancer cells overexpressing miR-611. miR-611 is frequently upregulated in primary tongue cancer. Results provide insight into the role of miR-611 in the pathogenesis of tongue cancer. We used micorarrays to detailed the genes regulated by miR-611 in SCC-15 cells.
Project description:Identification of influenza virus-derived peptides presented by Human Leukocyte Antigen (HLA) molecules of the C1R (Class I reduced) B-lymphoblastoid cell line, transfected with the HLA class I allele HLA-A*24:02, after influenza infection.
Project description:Investigation into the impact of the peptide repertoire of Human Leukocyte Antigen (HLA) class I molecules HLA-A*24:02 and HLA-B*57:01 on interactions with the inhibitory Killer cell Immunoglobulin-like Receptor (KIR) KIR3DL1.
Project description:In 2022, a global mpox outbreak occurred, and remains a concern today. The T cell memory response to MPXV infection has not been fully investigated. In this study, we evaluated this response in convalescent and MVA-BN vaccinated individuals using VACV-infected cells. Detailed phenotypic and scRNAseq analysis was focused on the immunodominant HLA-A*02:01-G5R18-26-specific CD8+ T cell response. T cells from convalescent individuals showed greater cytotoxicity, migratory potential to site of infection and TCR clonal expansion. Our study suggests a better functional profile of MPXV-specific memory T cells induced by natural infection, which may have an implication on the long-term protective responses to future infection.
