Abstract
Colostrum is the richest natural source of zoonutrients. Proline Rich Polypeptides (PRP) are active immune modulating zoonutrient peptides found in all mammalian colostrum. In particular PRP are thought to modulate thymus function, specifically the T helper 1 / T helper 2 (Th1 / Th2) balance. Th1, modulating cellular immunity, and Th2, modulating humeral immunity, are classified on the basis of the cytokines they produce.
