Lymphocytes and the Cellular Basis of Adaptive Immunity

WebNatural killer cells (NK cells) are white blood cells that destroy infected cells and cancer cells in your body. NK cells are important fighters in your immune system. Your immune system protects you from harmful invaders, like pathogens (viruses, bacteria and parasites) and cancer cells. NK cells belong to a specific group of white blood cells ... WebJul 30, 2024 · Think of a primary infection as a race between the pathogen and the immune system. The pathogen bypasses barrier defenses and starts multiplying in the host’s body. During the first 4 to 5 days, the innate immune response will partially control, but not stop, pathogen growth. WebJan 10, 2013 · The lack of chitin or chitosan in mammalian cells makes these polymers potential targets for recognition by the innate immune system. Though chitin and possibly chitosan in their native environment can be stained with low molecular weight dyes, they are not readily accessed by protein-sized probes. dymaxion round house
