TACHYKININ Meaning and
Definition
-
Tachykinin refers to a family of neuropeptides that play a crucial role in the central and peripheral nervous systems of mammals. These small signaling molecules are involved in various physiological processes and are widely distributed throughout the animal kingdom.
Tachykinins are known to be involved in the transmission of pain signals, regulation of blood flow, inflammation, gastrointestinal motility, and modulation of neurotransmitter release. They exert their functions by binding to specific receptors, known as tachykinin receptors, which are present on various cell types in the body.
These neuropeptides are primarily produced in nerve cells and are released in response to various stimuli, such as stress, injury, or inflammation. Upon release, tachykinins bind to their receptors, leading to the activation of intracellular signaling pathways and subsequent physiological responses.
There are several types of tachykinins, including substance P, neurokinin A, and neurokinin B, each with its own specific receptor profile and functions. Substance P, for example, is primarily associated with pain transmission, while neurokinin A is involved in smooth muscle contraction and blood vessel dilation.
Tachykinins have been widely studied due to their involvement in various physiological and pathological processes. They serve as important targets for the development of drugs aimed at treating conditions such as pain disorders, asthma, and inflammatory diseases.

Etymology of TACHYKININ
The word "Tachykinin" is derived from two components: "tachy" and "kinin".
The term "tachy" originates from the Greek word "tachys", meaning fast or rapid. In medical terminology, "tachy-" is used to describe something that is fast or accelerated.
The term "kinin" refers to a class of bioactive peptides that were first discovered in the venom of certain snakes. These peptides have various physiological effects, including causing blood vessels to dilate and increasing vascular permeability. The name "kinin" comes from the Greek word "kinein", which means to move or to set in motion.
Therefore, when combined, "tachykinin" refers to a family of peptides that are characterized by their ability to induce rapid responses in the body.
