How do innate cells recognize pathogens

WebOne of the first steps that certain immune cells take at the site of an infection is to secrete cytokines into the extra-cellular fluid. These cytokines, such as interleukins (IL) or tumor … 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.
