The immune response to an infection can be divided into the innate and adaptive phases that act in synergy to eliminate pathogens. Activation of the innate immune system following antigen detection results in rapid elimination of pathogen and prevention of infection. In contrast, the adaptive immune response develops after a time lag, but results in the activation of cells that are highly specific and effective in eliminating the pathogen. The quality and magnitude of the adaptive immune response is dependent on the innate immune response.Cells involved in the innate immune response include natural killer (NK) cells, natural interferon producing cells (NIPC), dendritic cells and macrophages...
