MC1R Biology and Melanocortin Signaling

Receptor biology, downstream signaling, and why selectivity matters.

Why MC1R Matters

This unit treats MC1R as the center of gravity for the afamelanotide story. Without that receptor frame, it is too easy to collapse approved drug use into generic "tanning peptide" language.
