Background: Toll-like receptors (TLRs) are key players in the innate immune system whose activation leads to an inflammatory response. Inflammation plays an important role in the pathogenesis of chronic kidney disease (CKD) and diabetes mellitus. The aim of our study was to assess the proinflammatory state of nondialysis CKD patients by evaluating the membrane expression of TLR2 and TLR4 and the intracellular IL-1β and IL-6 production in response to the ligand Pam3Cys-Ser-(Lys)4 (Pam3CSK4).

Objectives: Toll-like receptors (TLRs) are key players in the innate immune system. Recently, a pivotal role of TLR2 and TLR4 has been recognized in atherogenesis. We investigated the effect of simvastatin monotherapy or its combination with ezetimibe on TLR2 and TLR4 membrane expression and on lipopolysaccharide (LPS)-induced interleukin-1β (IL-1β) and interleukin-6 (IL-6) production in peripheral blood monocytes of patients with primary hypercholesterolemia.

We have previously reported the synthesis of a highly constrained cyclic peptide, that incorporates the -CDC- sequence, (S,S) PSRCDCR-NH(2), which potently inhibits aggregation and fibrinogen binding to human platelets in vitro. We have tested the safety and efficacy of the peptide on the electrically induced carotid artery thrombosis experimental rabbit model.
