toksyn

Toksyn is a toxin, a poisonous substance produced by living organisms or introduced into a biological system that disrupts normal cellular processes. Toxins can act at very low concentrations to damage cells or organs. In toxicology and related fields, toxins are categorized by their sources, mechanisms, and effects, and are studied for risks as well as potential therapeutic uses.

Biological sources include bacteria, plants, animals, and fungi. Examples range from bacterial AB toxins (such as those produced by Corynebacterium diphtheriae) to plant lectins and alkaloids, animal venoms, and fungal mycotoxins. Some toxins are enzymes that modify cellular targets; others form pores in membranes or interfere with nerve signaling. Venoms often contain complex mixtures of toxins.

Mechanisms vary: ribosome-inactivating toxins halt protein synthesis; neurotoxins disrupt neurotransmission; hepatotoxins damage liver cells; cytotoxins destroy cells. The clinical outcome depends on dose, exposure route, and the organism exposed, with symptoms ranging from nausea and dizziness to organ failure or death. Exposure can be acute or chronic.

Uses and safety: In medicine and research, certain toxins are used in controlled, minute doses for therapeutic or diagnostic purposes, such as botulinum toxin in neuromodulation. Many toxins have specific antidotes or management strategies, and regimens emphasize safety and regulatory oversight. Public health measures monitor and prevent poisoning from contaminated food, water, or environmental sources.
