Crosslinks collagen

WebCompromised collagen in the cornea, a condition known as keratoconus, can be treated with clinical crosslinking. [9] In biological context crosslinking could play a role in atherosclerosis through advanced glycation end-products (AGEs), which have been implicated to induce crosslinking of collagen, which may lead to vascular stiffening.

WebDeoxypyridinoline (Dpd) is a crosslink of type 1 collagen that provides tensile strength to the collagen matrix of bone. Dpd is released into circulation during bone resorption and is excreted unmetabolized into urine. Since Dpd levels are not affected by diet or physical exercise, urinary Dpd concentrations reflect the true rate of bone turnover. WebDec 14, 2016 · Here, we show that an enzyme that crosslinks collagen-Lysyl oxidase-like 2 (Loxl2)-is essential for interstitial fibrosis and mechanical dysfunction of pathologically stressed hearts. In mice, cardiac stress activates fibroblasts to express and secrete Loxl2 into the interstitium, triggering fibrosis, systolic and diastolic dysfunction of ...
