Activation of the High Mobility Group Box 1/Receptor for Advanced Glycation Endproducts /NOD-like Receptor Family Pyrin Domain-Containing 3 Axis Under Chronic Intermittent Hypoxia Induction Promotes the Progression of Atherosclerosis in ApoE Mice.

Background Chronic intermittent hypoxia (CIH) has been regarded as an important cause of atherosclerotic disease. In our study, we set out to investigate whether CIH regulated the high mobility group box 1/receptor for advanced glycation endproducts/NOD-like receptor family pyrin domain-containing 3 (HMGB1/RAGE/NLRP3) axis to affect the progression of atherosclerosis. Methods and Results Initially, peripheral blood samples were collected from patients with single obstructive sleep apnea, atherosclerosis complicated with obstructive sleep apnea, and healthy volunteers.

Loss of RAGE prevents chronic intermittent hypoxia-induced nonalcoholic fatty liver disease via blockade of NF-кB pathway.

In recent years, receptor for advanced glycation end-products (RAGE) has been documented to induce liver fibrosis and inflammatory reaction. Further, microarray data analysis of this study predicted high expression of RAGE in non-alcoholic fatty liver disease (NAFLD). However, its specific mechanisms remain to be elucidated.

Inhibition of the PD-1/PD-L1 signaling pathway enhances innate immune response of alveolar macrophages to mycobacterium tuberculosis in mice.

Background: Mycobacterium tuberculosis (TB) is a pathogen that consequently leads to TB infection, which remains a significant global health concern. Programmed death 1 (PD-1)/programmed death-ligand 1 (PD-L1) signaling pathway is critical for terminating immune responses. The present study aimed to elucidate the regulatory role of the PD-1/PD-L1 signaling pathway in alveolar macrophages against Mycobacterium TB in mice.
