WebSep 14, 2024 · A summary of key mechanisms for GAG/proteoglycan regulation of skin is found in Figure 2. Figure 2 Key biological activities of GAG & proteoglycans in skin. ( A) Proteoglycans act to present chemokines/cytokines to their cognate receptors. ( B) GAG chains on proteoglycan act as co-receptors for growth factor receptors (GF-R), … WebProteoglycans. Proteoglycans are GAG's that are covalently attached to a 'core' protein. All GAG's except hyaluronic acid attach to a protein in this way.These GAG-protein mixtures are very heterogeneous, and this variability means they can form pores of different sizes to regulate the sizes of molecules that can move through the matrix.
