Abstract:

Tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) is the leading cause of death from a single infectious agent worldwide, and there has been a large number of individuals who remain in a long-term latent infection state after being infected. The clearance of MTB in the body primarily relies on specific immune responses, in which T lymphocytes, as the main cells involved in cellular immunity. Their proliferation and activation play a crucial role during the specific immune response in the body. This review discusses the functions of CD4+ T cells and CD8+ T cells, two subsets of T lymphocytes, in the immune response MTB infection, and summarizes the mechanisms of the immune response against MTB infection in the body. It aims to provide insights for further exploration of the adaptive immune network against MTB infection,diagnosis of TB, and the development of new vaccines in clinical research.

Key words: Tuberculosis, CD4 positive T lymphocytes, CD8 positive T lymphocytes, Immunity, Cytokine
