Cytokines

Cytokines are a group of proteins that regulate interactions of immune cells. His immunoregulatory function is key in immune response, inflammation.Cytokines are a group of small molecular weight proteins synthesized by many cells particularly immune cells.ts function is immunoregulatory be fundamental in communication and interactions that establish the immune system cells with each other and with other cells. Cytokines direct the innate immune response and specific immune response and are involved in inflammation and hematopoiesis.
activated macrophages, eosinophils, neutrophils and NK cells, induce the production of reactive oxygen species and nitrogen and macrophages involved in hematopoietic processes. Involved in such important processes as inflammation, regulation of MHC expression (Major Histocompatibility Complex) class I and class II immunosuppressive responses, regulation of isotype switching of immunoglobulins,

Substance P

Substance P is the first neuroactive substance that is proposed as a neurotransmitter. As for the pharmacological properties of substance P, they were demonstrated to check exhibiting potent hypotensive properties that were not blocked by atropine. He was later identified as the first active neuropeptide and was proposed as a neurotransmitter. In the 70s the structure is now known to contain eleven amino acids, of which six corresponding to the C-terminus are essential for its biological activity was determined. Substance P (SP) is a neuropeptide of eleven amino acids, are much smaller than other neurotransmitters amounts, is synthesized in the cell body and transported along the axon to the terminals, it is synthesized as part of a prepropeptide ( preproteins or precursors) of higher molecular weight which then moves to the cisterns of the endoplasmic reticulum, where it is disintegrated to produce a proprotein. The proprotein is transported to the Golgi apparatus, where they may fac...
