What is the Origin of Neuro-Peptide?

The term is a compound of 'neuro,' referring to the nervous system, and 'peptide,' indicating its chemical structure as a short protein fragment. The discovery of these dual-function molecules revealed the intimate and inseparable connection between the brain and the body's hormonal network. Early research focused on molecules like Substance P and endorphins, establishing the field of neuroendocrinology.

What is the Mechanism of Neuro-Peptide?

Neuro-peptides are synthesized in the neuron's cell body, transported down the axon, and released into the synaptic cleft to modulate neurotransmission or into the bloodstream to act as circulating hormones, influencing distant target cells. For example, hypothalamic neuro-peptides like oxytocin and vasopressin are critical for social behavior and fluid balance. Their actions illustrate their profound regulatory power over fundamental biological drives and endocrine output.

Neuro-Peptide

Meaning

A neuro-peptide is a short chain of amino acids synthesized and released by neurons, functioning as a chemical messenger within the nervous system and often acting as a hormone in the peripheral circulation. These molecules are crucial regulators of diverse physiological processes, including pain perception, appetite, thirst, and the coordinated release of other hormones. They represent a fundamental communication link between the neural and endocrine systems, coordinating the brain-body axis.
