Innate immunity, also known as natural or genetic immunity, is immunity that an organism is born with. The key difference between innate and adaptive immunity is that innate immunity is a fast immune response that provides the first line of immunological defence against infections while adaptive immunity is a slow immune response mediated by the T and B lymphocytes.. The component of the immune system in animals that is genetically determined and is nonspecific, as distinguished from the adaptive immune system. We begin with the secreted cytokines that can influence the nature of the adaptive immune response, and how these may be tuned with the use of particular adjuvants.
