Module 2 — How Peptides Help

Peptides work by binding to cellular receptors or interacting with local signalling pathways. That binding can trigger cascades that increase protein synthesis, influence immune responses, or alter metabolic signals. Mechanisms differ between peptides; understanding them helps set realistic expectations.

Learning goals: identify common mechanisms (receptor binding, growth factor stimulation, immune modulation) and realistic downstream effects.
