What is the Origin of Cyclical Peptide Therapy?

This therapeutic concept is derived from the pharmacological principles of pulsatile hormone release and receptor pharmacology, where non-continuous exposure is known to maintain or even increase receptor sensitivity. The use of "cyclical" protocols is an evolution in peptide application, seeking to mimic the body's natural, rhythmic signaling.

What is the Mechanism of Cyclical Peptide Therapy?

The therapeutic action relies on the peptides binding to specific G protein-coupled receptors (GPCRs) or other surface receptors on target cells, initiating a cascade of intracellular signaling. By employing a cyclical schedule, the therapy prevents the internalization and down-regulation of these receptors, ensuring that the physiological response remains robust upon subsequent administration. This method preserves the natural feedback loops of the endocrine system.

Cyclical Peptide Therapy

Meaning

Cyclical Peptide Therapy is a clinical strategy involving the intermittent, structured administration of specific short-chain amino acid compounds, known as peptides, to elicit targeted biological effects without inducing long-term homeostatic suppression or receptor desensitization. This approach contrasts with continuous dosing by incorporating defined periods of treatment followed by washout or rest phases, thereby maximizing therapeutic efficacy and minimizing potential side effects. The goal is often to stimulate endogenous hormone release, enhance tissue repair, or modulate immune function.
