Recent findings reveal that macrophages actively control clearance by desialylating target cells via NEU1 and releasing cathepsin-cleaved calreticulin (CALR) to mark them for phagocytosis. This uncovers a dual role for CALR as immune activator or repressor, depending on its form and context, with distinct implications for cancer immunity.

Myocarditis is a life-threatening inflammatory disorder that affects the cardiac muscle tissue. Current treatments merely regulate heart function but fail to tackle the root cause of inflammation. In myocarditis, the initial wave of inflammation is characterized by the presence of neutrophils.

Macrophages play crucial roles in the progression of liver diseases. Increasing studies have shown that mesenchymal stem cells (MSCs) and their extracellular vesicles (MSC-EVs) could reshape the liver immune microenvironment by regulating the function and phenotype of macrophages, thereby exerting a therapeutic effect on liver diseases. Mitochondria, apart from being the central hub of energy metabolism, also finely regulate macrophage-mediated innate immune responses by modulating reactive oxygen species levels, cell polarization, and cell death.

Hypoxia plays a critical role in regulating the progression of non-small cell lung cancer (NSCLC) by modulating the tumor immune microenvironment (TIME). Tumor-associated macrophages (TAMs), important components of TIME, can be regulated by hypoxic conditions. Unfortunately, the molecular mechanisms by which hypoxia regulates TAMs in TIME to affect NSCLC progression has not been fully delineated.

Background: High % of low-voltage area (LVA), a surrogate of scar, is associated with atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Noninvasive biomarkers of LVA are a medical need for PVI decision.
Objective: We aimed to identify the proteome profile of plasma extracellular vesicles (EVs) associated with high % LVA, their cellular origin, and their regulation by hyperglycemia.
