The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants , fungi , prokaryotes , and invertebrates (see Beyond vertebrates ).
Innate immune systems are found in all animals. [2] If pathogens successfully evade the innate response, vertebrates possess a second layer of protection, the adaptive immune system, which is activated by the innate response. [3] Here, the immune system adapts its response during an infection to improve its recognition of the pathogen.
Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers. Phagocytosis , derived from the Greek words phagein , meaning to eat, kytos or cell, and “osis” meaning process, was first described by Élie Metchnikoff , who won the Nobel Prize 100 years ago.
Positive acute-phase proteins serve (as part of the innate immune system) different physiological functions within the immune system.Some act to destroy or inhibit growth of microbes, e.g., C-reactive protein, mannose-binding protein, [3] complement factors, ferritin, ceruloplasmin, serum amyloid A and haptoglobin.
Innate immunity is the first line of defense against cancer. It consists of non-specific immune cells that can recognize and destroy abnormal cells, including cancer cells. Natural killer (NK) cells, dendritic cells, and macrophages are some examples of innate immune cells that can detect and eliminate cancer cells. [4] Adaptive immunity, on ...
Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...

The acquired immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Google Ngram of "acquired immunity " vs. "adaptive immunity". The peak for "adaptive" in the 1960s reflects its introduction to immunology by Robert A. Good and use by colleagues; the explosive increase in the ...
