Abstract
Mycobacterium tuberculosis ( M.tb ) is a bacterial pathogen that has evolved in humans, and its interactions with the host are complex and best studied in humans. Myriad immune pathways are involved in infection control, granuloma formation, and progression to tuberculosis (TB) disease. Inflammatory cells, such as macrophages, neutrophils, conventional and unconventional T cells, B cells, NK cells, and innate lymphoid cells, interact via cytokines, cell-cell communication, and eicosanoid signaling to contain or eliminate infection but can alternatively mediate pathological changes required for pathogen transmission. Clinical manifestations include pulmonary and extrapulmonary TB, as well as post-TB lung disease. Risk factors for TB progression, in turn, largely relate to immune status and, apart from traditional chemotherapy, interventions primarily target immune mechanisms, highlighting the critical role of immunopathology in TB. Maintaining a balance between effector mechanisms to achieve protective immunity and avoid detrimental inflammation is central to the immunopathogenesis of TB. Many research gaps remain and deserve prioritization to improve our understanding of human TB immunopathogenesis.
期刊介绍:
Science Immunology is a peer-reviewed journal that publishes original research articles in the field of immunology. The journal encourages the submission of research findings from all areas of immunology, including studies on innate and adaptive immunity, immune cell development and differentiation, immunogenomics, systems immunology, structural immunology, antigen presentation, immunometabolism, and mucosal immunology. Additionally, the journal covers research on immune contributions to health and disease, such as host defense, inflammation, cancer immunology, autoimmunity, allergy, transplantation, and immunodeficiency. Science Immunology maintains the same high-quality standard as other journals in the Science family and aims to facilitate understanding of the immune system by showcasing innovative advances in immunology research from all organisms and model systems, including humans.
