The fate of disease-associated microglia (DAM) in neuropathologies remains elusive. Lan et al. generated an Spp1 fate-mapping model to track DAM-like microglia and find that the plasticity of DAM is age dependent. Juvenile stroke leads to the eliminati…
Non-alcoholic fatty liver disease and its progressive form, non-alcoholic steatohepatitis (NASH), are a prevalent cause of chronic liver disease. Savage et al. demonstrate that regulatory T (Treg) cells are enriched in mouse and human NASH and find tha…
Massoni-Badosa et al. present a comprehensive human tonsil cell atlas, identifying 121 cell types and states through multimodal single-cell profiling. This atlas elucidates cell differentiation pathways and regulatory circuits, defines cell states, and…
Mutations of the CBP/p300 histone acetyltransferase (HAT) domain can be linked to leukemic transition in humans. Jaschke et al. reveal that a small-molecule inhibitor of the CBP/p300 histone acetyltransferase activity acutely mobilizes leukocytes from …
When and how T cells make effector or memory decisions is not fully resolved. Abadie, Clark, and Valanparambil et al. uncover a reversible epigenetic switch enabling memory cells to diverge early after activation or dedifferentiate from effector cells …
Although it is known that pro- and anti-inflammatory neutrophils exist, the mechanisms that dictate their polarization remain unclear. Gour et al. report that neutrophils express a canonical neuronal receptor, Mrgpra1, and a neuropeptide ligand, neurop…
Tuft cells are central regulators of type 2 immunity in the intestine. Eshleman et al. reveal that commensal bacterial-derived butyrate restricts stem cell development into tuft cells through the epigenetic-modifying enzyme HDAC3. The microbiota can th…
Aging induces cellular senescence of immune cells, yet the underlying mechanism is poorly understood. Here, Zhou et al. reveal that type 2 cytokine signaling protects macrophages from senescence by directly sustaining DNA repair. They further show that…
High-affinity cells are proposed to preferentially develop into long-lived plasma cells. Sutton et al. examine the differentiation of Ighg2A10 B cells, specific for the Plasmodium falciparum circumsporozoite protein (PfCSP), and find that cells initiat…
