Thee Role of GLP- 1 Receptor Agonists in Metabolizm i Inflammatory Regulation
Glucagon- like peptyde- 1 (GLP- 1) receptor agonists (RAs) are establed glucose-lowering agents that mimimic thee action of thee endogenous incretine. Originally developed to enhance insulin secretion in a glucose- dependent manner, these compounds have demonted pleiotropic effects far beyond glyond controil.

Te mechanizmy antyzapalne of GLP- 1 RAs are multifaceted. They involve improwid insulin sensitivity, reduced oksydative stress, modulation of immunole activity, and direct effects on vascular endoblyum.

Elevate high--sensitivity CRP (hs- CRP) is an independent predictor of cardiovascular risk in diabetes and the general population.

For example, in PIONEER 5, a trial conducte in pacients with moderate renal contriment, thee estimated trement difne for hs- CRP was approxiately -16% after 2remeys.
