Early secreted antigen ESAT-6 of Mycobacterium Tuberculosis promotes apoptosis of macrophages via targeting the microRNA155-SOCS1 interaction.
BACKGROUND The early secreted antigenic target 6-kDa protein (ESAT-6) of Mycobacterium tuberculosis (Mtb) not only acts as a key player for virulence but also exhibits a strong immunotherapeutic potential against Mtb. However, little is known about the molecular basis for its potential in immunotherapy. The present study was designed to unravel the role of miRNA-155 in ESAT-6-mediated enhanceme...
متن کاملDifferential Early Secreted Antigen Target (ESAT) 6 kDa-induced IFN-γ and SOCS1 expression distinguishes latent and active tuberculosis.
INTRODUCTION Expression of Suppressor of cytokine signaling (SOCS)-1 molecules is increased in patients with tuberculosis (TB). Early Secreted Antigen Target (ESAT)-6 kDa - induced IFN-γ responses indicate Mycobacterium tuberculosis infection. The effect of ESAT6- stimulation on SOCS1 in the host is not known. METHODOLOGY Healthy asymptomatic controls had a negative (n = 16) or a positive ( n...
متن کاملSelection of single-chain variable fragments specific for Mycobacterium tuberculosis ESAT-6 antigen using ribosome display
Objective(s): Tuberculosis (TB) is still one of the problematic infectious diseases in developing countries, especially in Iran. In the present study, we applied ribosome display technique to select single chain variable fragments (scFvs) specific for the 6-kDa early secretory antigenic target (ESAT-6) antigen of Mycobacterium tuberculosis from a mouse scFv library. Materials and Methods: The g...
متن کاملBAT3 Regulates Mycobacterium tuberculosis Protein ESAT-6-Mediated Apoptosis of Macrophages
HLA-B-associated transcript 3 (BAT3), also known as Scythe or BAG6, is a nuclear protein implicated in the control of apoptosis and natural killer (NK) cell-dendritic cell (DC) interaction. We demonstrate that BAT3 modulates the immune response by regulating the function of macrophages. BAT3 is released by macrophages in vitro and it down-regulates nitric oxide and proinflammatory cytokines rel...
متن کاملMycobacterium tuberculosis ESAT-6 antigen immunogenicity in Owl Monkeys
Several ESAT-6-based vaccines have been widely studied in different animal models, presenting potent ability to induce both cellular and humoral responses. As ESAT-6 is a well-characterized mycobacterial antigen, its capacity to induce immune responses in a nonhuman primate model has been evaluated. The immunization of recombinant ESAT-6 (rESAT-6) in Aotus nancymaae monkeys has elicited a stron...
