This refers to the targeted application of short chains of amino acids, or peptides, administered therapeutically to modulate specific endocrine or physiological functions. These molecules act as signaling agents, instructing cells to perform specific actions related to repair, growth, or regulation. We utilize their inherent biological specificity to address deficiencies or imbalances at a fundamental cellular level.
Origin
The term originates from biochemistry, describing the structural nature of peptides as smaller protein fragments. In a clinical context, it signifies a sophisticated evolution beyond traditional hormone replacement, focusing on targeted receptor interaction rather than broad systemic saturation. This approach respects the body’s natural signaling architecture.
Mechanism
Peptides operate by binding with high affinity to specific cell surface receptors, initiating intracellular cascades that influence gene expression or cellular activity. For example, certain peptides can stimulate growth hormone release from the pituitary or enhance insulin sensitivity in peripheral tissues. This mechanism allows for precise modulation of complex feedback loops within the human physiology.
