Twelve mycobacterial antigens were compared for induction of gamma interferon (IFN-gamma) secretion by human blood mononuclear cells of patients with leprosy. Fractionated Mycobacterium leprae antigens containing cell wall proteins or cytosolic and membrane proteins induced good IFN-gamma responses in tuberculoid leprosy patients. Lipoarabinomannan from M. tuberculosis Erdman and M. leprae mycolylarabinogalactan peptidoglycan were the poorest IFN-gamma inducers.

BCG remains the only licensed vaccine for tuberculosis (TB), but its efficacy wanes over time. Subunit vaccines, aim to improve BCG immunity and protection, by inducing responses to a few mycobacterial antigens delivered with a specific platform. Since the platform shapes the immune response induced, selecting the right platform has been challenging due to the lack of immune correlates of protection.

Bovine tuberculosis (bTB), a global zoonotic disease, causes negative effects on human and animal health. PhoP protein is a key regulator of pathogenic phenotypes in members of the Mycobacterium tuberculosis complex, which includes the causative agent of bTB. Despite extensive research on this protein focused in deciphering its regulatory role, little was explored about it as a diagnostic antigen.

Mycobacterium tuberculosis Complex (MTBC), the etiological agent of tuberculosis (TB), demonstrates considerable genotypic diversity with distinct geographic distributions and variable virulence profiles. The pe-ppe gene family is especially noteworthy for its extensive variability and roles in host immune response modulation and virulence enhancement. We sequenced an Mtb genotype L2.

Mycobacterium tuberculosis causes human tuberculosis. As mycobacteria are protected by thick lipid cell wall, humans have developed immune responses against diverse mycobacterial lipids. Most of these immunostimulatory lipids are known as adjuvants acting through innate immune receptors, such as C-type lectin receptors.

Tuberculosis represents a significant menace to health, leading to millions of cases and fatalities each year. Traditional diagnostic methods, while effective, have limitations, necessitating improved tools. Aptamers possessing remarkable specificity single-stranded DNA or RNA molecules promising in TB diagnosis due to their adaptability and precise biomarker detection capabilities.
