IPA: /ˈɔːtəˌkɔɪd/
KK: /ɔːtəˈkɔɪd/
A type of substance produced by the body that acts like a hormone or neurotransmitter, influencing various physiological processes.
Histamine is an example of an autocoid that plays a role in allergic reactions.
Autocoid is formed from "auto-" (meaning self) and "coid" (from Greek "eidos", meaning form or shape). The word refers to substances that are produced by the body and act on the same cells that produce them, hence self-acting substances.
Think of 'self' ('auto-') and 'form' ('coid') to remember that autocoids are substances that act on the same cells that produce them.
