Metchnikoff became interested in the study of microbes, and especially the immune system. At Messina he discovered phagocytosis after experimenting on the larvae of starfish. In 1882 he first demonstrated the process when he inserted small citrus thorns into starfish larvae, then found unusual cells surrounding the thorns. He realized that in ...
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 immune system is a network of biological systems that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to bacteria, as well as cancer cells, parasitic worms, and also objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major ...
The immune repertoire is affected by several factors: Age: as the immune system develops over life, lymphocytes generate their own unique gene sequences. Developed cells eventually die, but may not be replaced by new subtypes. [1] Exposure to diseases triggers further development of the immune repertoire, and thus fine-tunes the immune response.
Immunopathology is a branch of medicine that deals with immune responses associated with disease.It includes the study of the pathology of an organism, organ system, or disease with respect to the immune system, immunity, and immune responses.
In 2016, John Lin head of Pfizer's San Francisco biotech unit stated, “the immune system will be the most convenient vehicle for [engineered human cells], because they can move and migrate and play such important roles.” [3] Advances in systems biology support high-dimensional quantitative analysis of immune responses.

The second study [10] suggested the possibility that the immune system detected "danger", through a series of what is now called damage-associated molecular pattern molecules (DAMPs), working in concert with both positive and negative signals derived from other tissues.
The history of immunology and the medical study of the immune system dates back to the 19th century. The first Nobel Prize in the field of immunogenetics was awarded to Baruj Benacerraf, Jean Dausset and George Davis Snell in 1980 for discovering genetically determined cellular surface structures, which control immunological reactions.
