Trends Immunol. 2025 Jun 30:S1471-4906(25)00142-5. doi: 10.1016/j.it.2025.06.001. Online ahead of print. ABSTRACT Macrophages are sentinels and first responders of the innate immune system. By sensing danger signals, they initiate and amplify inflammatory and regenerative cascades to control appropriate responses to pathogens and tissue damage. Transcriptional activation of macrophage gene expression has been studied extensively, but … Read more

ABSTRACT Lassa virus (LASV), which causes deadly Lassa fever (endemic in Western Africa), is a priority pathogen and a global health threat. Current vaccine candidates protect LASV-challenged animals through T cell immunity or non-neutralizing IgG/Fc receptor-mediated functions in the absence of potent neutralization. Neutralizing … Read more

ABSTRACT Two recent studies, by Ely et al. and Apavaloaei et al., revealed that non-canonical antigens derived from unmutated, noncoding regions dominate the immunopeptidome of many cancers. Here, we discuss how this challenges conventional mutation-centric immunotherapies and highlight emerging strategies, including cryptic antigen- and … Read more

ABSTRACT Exploiting specific T cell subset properties bears potential for T cell therapies but is complicated by inconsistencies in T cell subset definitions and markers. Here, we discuss causes for the definition and classification complexities to provide a handle for how to navigate the … Read more

ABSTRACT Multiomics advances have led to breakthroughs in understanding human early life immunity. Adaptive memory immune cells have been detected in fetal tissue extremely early in gestation, where they may respond to maternal exposures. These promising findings lay the groundwork for future research on … Read more

We propose that the immune system, which can be redistributed across tissues (‘immune innervation’), cooperates with the nervous system to form a larger integrative network that can maximize the number of adaptive physiologic states to a … Read more

ABSTRACT Active regulation of T cell quiescence is important to sustain immune responses to vaccination and infection while preventing inappropriate responses such as autoimmunity. Recent studies highlight that quiescence in naïve T cells is actively regulated by transcription factors and tonic signaling. Loss of … Read more

ABSTRACT Understanding the mechanisms implicated in the establishment of trained immunity could aid the design of novel therapeutic approaches. By studying Bacille Calmette-Guerin (BCG) vaccination in a human cohort, Ziogas and colleagues demonstrate the role of lactate generation and its use for histone lactylation … Read more

ABSTRACT Microglia replacement is reshaping neurodegenerative disease therapy, yet its key prerequisites remain unclear. In the current issue of Immunity, Aisenberg et al. and Bastos et al. reveal how developmental origin influences monocyte engraftment into the brain, and demonstrate the therapeutic potential of monocyte-based … Read more

ABSTRACT N6-methyladenosine (m6A) is a key mRNA modification influencing mRNA stability and translation. YTHDF2, a major m6A ‘reader’, was initially recognized for promoting mRNA decay but is now also known to enhance translation by binding to methylated mRNAs. YTHDF2 maintains the function of immune … Read more
