Biology of IL-27 and its Role in the Host Immunity against Mycobacterium Tuberculosis
نویسندگان
چکیده
IL-27, a heterodimeric cytokine of IL-12 family, regulates both innate and adaptive immunity largely via Jak-Stat signaling. IL-27 can induce IFN-γ and inflammatory mediators from T lymphocytes and innate immune cells. IL-27 has unique anti-inflammatory properties via both Tr1 cells dependent and independent mechanisms. Here the role and biology of IL-27 in innate and adaptive immunity are summarized, with special interest with immunity against Mycobacterium tuberculosis.

Tuberculosis is a vagarious infectious disease that generally affects the lungs. Accordingly, in some cases, it can also affect the liver and kidney. Host genetic may affect tuberculosis caused by bacillus Mycobacterium tuberculosis. The main risk factors for the disease are a weakened immune system because of diabetes, some cancers, HIV/AIDS, severe kidney disease, cancer treatment, a...
متن کاملA study on the immune response induced by a DNA vaccine encoding Mtb32C-HBHA antigen of Mycobacterium tuberculosis
Objective(s): Tuberculosis (TB) has still remained a global health issue. One third of the world's population is infected with tuberculosis and the current BCG vaccine has low efficiency; hence, it is necessary to develop a new vaccine against TB. The aim of the current study was to evaluate the efficiency of a novel DNA vaccine encoding Mtb32C-HBHA antigen in inducing specific immune responses...
متن کاملBiochemical characterization of PE_PGRS61 family protein of Mycobacterium tuberculosis H37Rv reveals the binding ability to fibronectin
Objective(s): The periodic binding of protein expressed by Mycobacterium tuberculosis H37Rv with the host cell receptor molecules i.e. fibronectin (Fn) is gaining significance because of its adhesive properties. The genome sequencing of M. tuberculosis H37Rv revealed that the proline-glutamic (PE) proteins contain polymorphic GC-rich repetitive sequences (PGRS) which have clinical importance i...

Introduction: Mycobacterium ulcerans is the etiological agent of Buruli ulcer (BU) the third most common mycobacterial infection in humans after tuberculosis and leprosy. BU is now considered by the WHO to be an emerging infection of major concern. M. ulcerans produces mycolactone toxin, which is required for the organism’s virulence. Mycolactone destroys tissue and suppresses host immune respo...
متن کاملCD4+ cells play a limited role in murine lung infection with Mycobacterium kansasii.
Mycobacterium kansasii has emerged as an important nontuberculous mycobacterium that can cause severe infection in the immunocompromised host, especially in human immunodeficiency virus-infected patients. However, little is known about the pathogenesis of this infection. Because patients suffering from M. kansasii infection are severely compromised in their cellular immune response, we studied ...
