TREM2 drives accumulation of pro-scarring monocyte-derived macrophages in the infarcted myocardium

Myocardial infarction is a leading cause of death and disability worldwide. Ischemic injury leads to irreversible loss of cardiomyocytes, the contractile cells of the heart, and formation of a fibrotic scar. After infarction, macrophages massively infiltrate the heart and orchestrate the tissue repair process by removi...

Identification of a spatially organized TREM2-associated permissive macrophage niche in human pulmonary tuberculosis alveolar pneumonia

Pulmonary tuberculosis (TB), caused by lung infection with Mycobacterium tuberculosis (Mtb), often manifests both alveolar pneumonia and aggregation of immune cells containing Mtb, termed granulomas, within the same lung. Here, we integrate spatial transcriptomics, single-cell RNA sequencing, high-resolution imaging, a...

Somatic mutations reveal the ontogeny of microglia in human ageing.

An approach that uses the collection of accumulated somatic mutations that uniquely labels each clone of cells to track the infiltration of bone-marrow-derived cells into the human brain finds evidence of an influx of bone-marrow-derived cells into the brain in all examined individuals.
