The immune system is a key contributor to organismal aging. Here, Ping et al. leverage single-cell multi-omics to construct a human immune aging clock, which pinpoints T cells as an aging nexus. RUNX1 orchestrates a transcriptional network that restrai…
Inducing broadly neutralizing antibodies (bnAbs) remains a challenge in HIV vaccine development. Mishra et al. show that an engineered germline-targeting HIV trimer, Q23-APEX-GT2, primes rare V2-apex bnAb precursors in humanized mice and outbred macaqu…
The generation of immune memory is at the crux of vaccine efficacy. Here, Crotty reviews the layers of adaptive immunity—T cell, B cells, and antibodies—and their integration to generate a holistic view of vaccine response. Common misconceptions and qu…
Innate immune cell death is critical for host defense but drives inflammatory disease when dysregulated. In this issue of Immunity, Huang et al. report that the complement protein C1q activates macrophage mitochondrial SARM1 to deplete NAD+ and produce…
A lethal feature of glioblastoma is its ability to spread within the brain. In this issue of Immunity, Nebeling et al. use longitudinal three-photon imaging in an immunocompetent glioblastoma model to show that microglial responses at the far infiltrat…
RORγt is a key transcriptional regulator across diverse immune subsets. In this issue of Immunity, Fukui et al. show how Runx controls RORγt expression during early development and link progenitor specification to the diversification of RORγt+ innate i…
Immune experience can durably shape innate lymphocytes and their environments. Gasteiger and colleagues discuss how training, memory-like features, and dynamic niche interactions reprogram NK cells and ILCs to adapt their functions and tissue specializ…
In this review, Barreiro and colleagues synthesize molecular and cellular mechanisms of trained immunity across monocytes, tissue-resident macrophages, and HSPCs. They propose a unifying framework linking transcription factor activity, metabolic remode…
In Alzheimer’s disease (AD), glial crosstalk surrounding amyloid-β (Aβ) plaques establishes a self-reinforcing inflammatory circuit; however, its underlying mechanisms are incompletely understood. Zhang et al. find that astrocytic PAD2 citrullinates vi…
Vendramin et al. identify nonsense-mediated mRNA decay (NMD) as a central constraint on tumor antigenicity. Inhibiting the NMD kinase SMG1 stabilizes aberrant NMD-targeted transcripts and reveals a previously inaccessible class of non-canonical, non-mu…
