Project description:To determine if there is differential gene expression response to Mycobacterium tuberculosis in neutrophils from persons living with HIV who remain tuberculin skin test (TST) and inteferon gamma release assay (IGRA) negative and have no tuberculosis history (HITTIN) compared to persons living with HIV and no previous TB but TST and IGRA positive (HIT).
Project description:To compare gene expression changes induced by infection with Mycobacterium tuberculosis (Mtb) with changes induced by purified Mtb products, we infected THP-1 cells with Mtb strain H37Rv or treated with purified Mtb products, then performed RNAseq.
Project description:Trained Immunity (TRIM) is the phenomenon whereby innate immune cells such as monocytes or macrophages undergo functional reprogramming after exposure to specific microbial or metabolic components. In this study, monocytes were trained with beta-glucan and then re-exposed to Mycobacterium tuberculosis.
