Project description:Several HLA allelic variants have been associated with protection from, or susceptibility to infectious and autoimmune diseases. Here, we examined whether specific HLA alleles would be associated with different Mtb infection outcomes. We found that DQA1*03:01, DPB1*04:02, and DRB4*01:01 were signficantly more frequent in inividuals with active TB (susceptibility alleles). Furthermore, individuals who express any of the three susceptibility alleles were associated with lower magnitude of responses against Mtb antigens. We investigated the gene expression changes induced in PBMCs by Mtb lysate and a peptide pool (MTB300) in individuals with or without expression of the susceptibility alleles.

Project description:The dataset consists of Oxford Nanopore targeted RNA-based amplicon data of 12 classical HLA genes (HLA-A, -B, -C, -DRA, -DRB1, -DRB3, -DRB4, -DRB5, -DQA1, -DQB1, -DPA1, and DPB1) of 50 healthy individuals. The 12 classical genes were sequenced in two separate gene pools on R9.4 flowcells using MinION sequencer. Per individual, gene pool 1 contains HLA-A, -B, -C, -DRB1, -DRB3, -DRB4, -DRB5, and -DPB1 and gene pool 2 HLA-DRA, -DQA1, -DQB1, and -DPA1. The dataset includes 100 fastq files of Oxford Nanopore 2D reads (50 for gene pool 1 and 50 for gene pool 2).

Project description:Thirty-eight tumors from 17 patients treated with BRAF inhibitor (n=12) or combination BRAF/MEK inhibitors (n=5) with known PD-L1 expression were analyzed. RNA expression arrays were performed on all pre-treatment (PRE, n=17), early during treatment (EDT, n=8) and progression (PROG, n=13) biopsies. HLA-A/HLA-DPB1 expression was assessed by immunohistochemistry (IHC). Gene set enrichment analysis (GSEA) of PRE, EDT and PROG melanomas revealed that transcriptome signatures indicative of immune cell activation were strongly positively correlated with PD-L1 staining. In contrast, MAPK signaling and canonical Wnt/-ß-catenin activity were negatively associated with PD-L1 melanoma expression. The expression of PD-L1 and immune activation signatures did not simply reflect the degree or type of immune cell infiltration, and was not sufficient for tumor response to MAPK inhibition.

Project description:Platelet-rich fibrin (PRF) and Enamel Matrix Derivatives (EMD) can support the local regenerative events in periodontal defects. There is reason to suggest that PRF and EMD exert part of their activity by targeting the blood-derived cells accumulating in the early wound healing blastema. However, the impact of PRF and EMD on blood cell response remains to be discovered. To this aim, we have exposed human peripheral blood mononucleated cells (PBMCs) to PRF lysates and EMD, followed by bulk RNA sequencing. A total of 111 and 8 genes are up- and down-regulated by PRF under the premise of an at least log2 two-fold change and a minus log10 significance level of two, respectively. Representative is a characteristic IFN response indicated by various human leukocyte antigens (HLA-DPA1, HLA-DPB1, HLA-DQA1, HLA-DQA2, HLA-DRA, HLA-DRB1, HLA-DRB5), gamma Fc receptors (FCGR1A, FCGR1B, FCGR3B), chemokines (CXCL9-11), and calprotectin (S100A8/9 and S100A12), complement (C1QA/B, C2) and interferon-induced guanylate-binding proteins (GBP1, GBP5). With EMD, 67 and 29 genes are up- and down-regulated, respectively. Characteristics of the upregulated genes are tensins (TNS1 and TNS3). Among the genes downregulated by EMD were epsilon Fc receptors (FCER1A; FCER2) and Fc receptor-like proteins (FCRL1, FCRL3) and CX3CR1. Genes commonly upregulated by PRF and EMD were most noticeably NXPH4 and MN1, but also FN1, MMP14, MERTK, and AXL. Our findings suggest that PRF provokes an inflammatory response, while EMD dampens IgE signaling in peripheral mononucleated blood cells.
