In certain conditions, the regulation rather than the intrinsic activity of parts of the immune system is the predominant problem. [7] Immunodeficiency with hypopigmentation or albinism: Chédiak–Higashi syndrome, Griscelli syndrome type 2; Familial hemophagocytic lymphohistiocytosis: perforin deficiency, UNC13D deficiency, syntaxin 11 deficiency
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 .
The first called IgM is highly effective at neutralizing viruses but is only produced by the cells of the immune system for a few weeks. The second, called, IgG is produced indefinitely. Therefore, the presence of IgM in the blood of the host is used to test for acute infection, whereas IgG indicates an infection sometime in the past. [ 8 ]
Thus it may be possible, to take a large sample of cells from someones immune system, and look quickly at the range of sub-types present in the sample. The ability to obtain data quickly from tens or hundreds of thousands of cells, one cell at a time, should provide a good idea, of the size of the person's immune repertoire.
This antigen presentation pathway enables the immune system to detect transformed or infected cells displaying peptides from modified-self (mutated) or foreign proteins. [ 5 ] [ 6 ] In the presentation process, these proteins are mainly degraded into small peptides by cytosolic proteases in the proteasome , but there are also other cytoplasmic ...
A representation of the cholera epidemic of the 19th century. For thousands of years mankind has been intrigued with the causes of disease and the concept of immunity. The prehistoric view was that disease was caused by supernatural forces, and that illness was a form of theurgic punishment for "bad deeds" or "evil thoughts" visited upon the soul by the gods or by one's enemies.

An immune response is a physiological reaction which occurs within an organism in the context of inflammation for the purpose of defending against exogenous factors. These include a wide variety of different toxins, viruses, intra- and extracellular bacteria, protozoa, helminths, and fungi which could cause serious problems to the health of the host organism if not cleared from the body.
