WitrynaAntibodies alone are often not enough to protect the body against pathogens. In these instances, the immune system uses cell-mediated immunity to destroy infected body cells. T cells are responsible for cell-mediated immunity. Killer T cells (cytotoxic T cells) assist with the elimination of infected body cells by releasing toxins into them and ... Witryna12 mar 2009 · An antibody-independent function of B cells in priming optimal primary and secondary immune responses against the intracellular bacterial pathogen F. tularensis has also been reported 78. Furthermore, activated B cells serving as antigen-presenting cells have been utilized to enhance anti-tumor immunity 79 .
WitrynaTuberculosis (TB), a zoonosis characterized by chronic respiratory infections, is mainly caused by Mycobacterium tuberculosis and is associated with one of the heaviest disease burdens in the world. Dendritic cells (DCs) play a key role and act as a bridge between innate and adaptive immune responses against TB. DCs are divided into … WitrynaConclusions. Resistance to intracellular bacterial infections involves almost all the components of the immune system and mainly T cells. The immune response tends …

WitrynaCell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic cells. It is most effective in removing virus-infected cells, but also participates in defending against fungi, protozoans, cancers, and intracellular bacteria.
