Here here for retiring an often overgeneralized M1-M2 binary phenotypic framework. #macrophages express an incredible large array of sensome receptors that allow them to tailor their phenotype and reactions to the needs of incredibly local environments. #neuroskyence #immunosky #glia

Awesome discussion for those of us who love resident #macrophages in all their forms, and wonder what allows some to be be self renewing

Resident tissue #macrophages (RTM) are now recognized as integral regulators of tissue physiology, not transient immune sentinels. one fundamental question remains unresolved: why do some populations achieve lifelong self-maintenance, while others are replaced under steady-state conditions? 🧵1/11

#Macrophages are essential for this process but how they are instructed inside the injured heart remaines unclear. We wanted to understand the local signals that push them towards regeneration. So we combined #singlecell RNA-seq with #spatial #transcriptomics to map the regenerating hearts.

Excited to share our #preprint showing that #macrophages in the regenerating #zebrafish #heart are shaped by local cardiac-immune microniches, with a fibroblast-to-macrophage signal promoting regeneration over fibrotic repair www.biorxiv.org/content/10.6...
