Does inactivation of CD73 promote atherogenesis in apolipoprotein E-deficient mice?
Lack of CD73 promotes atherogenesis most likely by de-inhibition of resident macrophages and T cells. Elevated Edn1 and TG levels may have contributed. This establishes CD73-derived adenosine as a direct or indirect regulator of atherogenesis.
AhR agonists increase MMP-1 expression in bronchial epithelial cells. The underlying AhR pathway involves CaMKII, MAPKs, and AP-1 elements. The upregulated MMP-1 further activated MMP-2 and MMP-9. Asthmatic patients have higher serum MMP-1 level. This novel regulatory pathway is a potential target for treating asthma.
