Abstract:

Both innate and adaptive immune responses play crucial roles in combating Mycobacterium tuberculosis (MTB) infection, while the development of drug resistance is also correlated with the immune response. It has been revealed that pulmonary myeloid cells mount an immune response against MTB, participating in host protection and contributing to the inflammatory process. Various cell types within the adaptive immune response elicit an immune response against MTB infection, with antigen-specific CD4+ T cells playing a major role in controlling the infection. However, in the complex MTB infection environment, different myeloid cells and CD4+ T cells may also act as key players in MTB infection, mediating the occurrence of pathological reactions. Therefore, this review aims to summarize the dual role of different myeloid cells (including monocytes, macrophages, dendritic cells) and CD4+ T cells in MTB infection.
