Cellular Immunity
Cellular Immunity involves the actions of various immune cells to protect an organism from infection and disease. These cells, including T cells, B cells, macrophages, neutrophils, and dendritic cells, recognize and eliminate foreign substances or abnormal cells in the body. They do this through a complex network of interactions that include antigen presentation, cell-cell communication, and the release of cytokines and chemokines. Cellular Immunity plays a crucial role in the adaptive immune response, providing long-lasting protection against specific pathogens and preventing reinfection. In the context of Zoology and Immunobiology, understanding Cellular Immunity is essential for studying animal disease resistance, host-pathogen interactions, and the development of vaccines and immunotherapies.
