Project description:Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), capable of manipulating and circumventing the host's immune system to establish infection. Ubiquitination plays a crucial role in the host's response to pathogens; however, the global alterations in protein ubiquitination during Mtb infection remain poorly understood. To elucidate the regulatory roles of ubiquitination in the immune response to Mtb, we investigated the ubiquitome of human macrophages following Mtb infection.
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).
