Arterial atherosclerosis is an inflammatory disease. Macrophages play a major role in the pathogenesis and progression of atherosclerotic lesions. Modulation of macrophage function is a therapeutic target for the treatment of atherosclerosis. Calponin is an actin-filament-associated regulatory protein that inhibits the activity of myosin-ATPase and dynamics of the actin cytoskeleton. Encoded by the Cnn2 gene, calponin isoform 2 is expressed at significant levels in macrophages. Deletion of calponin 2 increases macrophage migration and phagocytosis. In the present study, we investigated the effect of deletion of calponin 2 in macrophages on the pathogenesis and development of atherosclerosis. The results showed that …

Preterm birth is defined as the delivery of a live baby prior to the 37th week of gestation. It is the leading cause of neonatal mortality worldwide. Preterm neonates are at a higher risk for short- and long-term complications, and prematurity places significant burden on our society. Elucidation of the mechanisms that lead to spontaneous preterm labor will enable development of therapies to prevent this syndrome. We aimed to study pathological inflammation that is implicated in the pathophysiology of spontaneous preterm labor.

Pathological inflammation can be initiated by the activation of innate immunity either by microorganisms or alarmins, which are …
