Multiple tissue and immune cell populations in injured myocardium

The term Multiple tissue and immune cell populations in injured myocardium refers to the complex and dynamic cellular landscape that emerges in the heart following an insult, such as myocardial infarction or myocarditis. This environment is characterized by the interaction of resident cells—including cardiomyocytes, fibroblasts, and endothelial cells—with a diverse array of infiltrating immune cells such as neutrophils, monocytes, macrophages, and T-lymphocytes (Source: Nature Cardiovascular Research, 2022). These populations collectively orchestrate the transition from an initial pro-inflammatory phase to a reparative phase involving scar formation and tissue remodeling (Source: Circulation, 2020). While this cellular milieu contains numerous individual proteins and receptors that serve as therapeutic targets, the phrase itself describes a biological context or microenvironment rather than a single druggable molecule. Modern research often employs single-cell RNA sequencing and spatial transcriptomics to map these populations and identify specific molecular drivers of heart failure progression (Source: JACC: Basic to Translational Science, 2021).
