what cells are involved in nonspecific or innate immunity?

Nonspecific or innate immunity involves several key cell types, including macrophages, neutrophils, natural killer (NK) cells, and dendritic cells. Macrophages and neutrophils are pivotal in phagocytosing pathogens and debris, while NK cells target and destroy infected or cancerous cells. Dendritic cells play a crucial role in capturing and presenting antigens to activate the adaptive immune response. Together, these cells provide a rapid and generalized defense against a wide range of pathogens.
