Description
Pep-1 is a cell-penetrating peptide used to carry large conjugated structures across cell membranes. Pep-1 inhibits low molecular weight hyaluronan binding to toll-like receptor 4 (TLR4) and other receptors. Pep-1 also decreases intestinal and colonic length, decreases expression of IGF-1 and epiregulin, and decreases intestinal epithelial cell proliferation in vivo.
