However, how viral-induced maternal perturbations impact fetal brain macrophages remains insufficiently clear. Here, we demonstrated that inflammatory decidual natural killer (NK) cells, triggered by viral infection-induced maternal immune activation, drove macrophage activation, neurodevelopmental disorders, and behavioral deficits in offspring. Extracellular granzyme B (GzmB), predominantly released by the maternal CD49a<sup>+</sup> tissue-resident NK subset under type I interferon stimulation, crossed the maternal-fetal barrier and promoted interferon-stimulated gene (ISG)-expressing fetal macrophage accumulation and microglial activation. Targeting extracellular GzmB through the systemic administration of the serine protease inhibitor Serpina3n or genetic ablation of <em>Gzmb</em> in maternal NK cells mitigated neuroimmune disorders in the fetal brain. These findings suggest that exposure to a perturbed maternal milieu reprograms decidual NK cell immunity, disrupting fetal neuroimmune homeostasis and increasing offspring susceptibility to neurodevelopmental disorders later in life.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":"124 1","pages":""},"PeriodicalIF":32.4,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144065975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we identified a glycosylation-dependent program driven by galectin-1 (GAL1) that imparted both immunoregulatory and pro-angiogenic functions to MDSCs through shared receptor signaling pathways. GAL1 expression was associated with enhanced MDSC phenotypes and poor prognosis in diverse human cancers. Analysis of monocytic and polymorphonuclear MDSCs from tumor-bearing mice revealed niche-specific glycan signatures that selectively regulated GAL1 binding. Through glycosylation-dependent interactions with the CD18-CD11b-CD177 receptor complex and STAT3 signaling, GAL1 simultaneously orchestrated immunosuppressive and pro-angiogenic programs in MDSCs, driving tumor growth <em>in vivo</em>. Myeloid-specific deletion of β-galactoside α(2,6)-sialyltransferase 1, which prevented α(2,6)-linked sialic acid incorporation, enhanced GAL1-driven regulatory circuits and accelerated tumor progression, effects that were mitigated by GAL1-neutralizing antibodies. Thus, targeting GAL1-glycan interactions may offer opportunities to reprogram MDSCs and enhance the efficacy of immunotherapeutic and anti-angiogenic strategies.","PeriodicalId":13269,"journal":{"name":"Immunity","volume":"52 1","pages":""},"PeriodicalIF":32.4,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144065974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmembrane protein 119 (TMEM119) is a homeostatic marker of microglia but has not been fully studied under AD pathological conditions. Here, we observed that amyloid-beta (Aβ) induced a decrease in TMEM119 expression in microglia, and TMEM119 deficiency increased AD progression in the 5×FAD mouse model. TMEM119 bound to Aβ oligomers and recruited low-density lipoprotein receptor 1, which in turn degraded TMEM119 itself. Overexpression of TMEM119 in microglia enhanced their phagocytic activity and alleviated cognitive deficits in 5xFAD mice. Administration of the small molecules Kartogenin and SRI-011381, which we found enhanced TMEM119 expression, substantially promoted Aβ clearance and improved cognitive function in AD mice, even during the mid-stage of the disease.

Here, we examined the transcriptional regulation of type 2 immunity, focusing on the NF-κB pathway, which is differentially activated by TCR engagement or cytokine signaling. Conditional deletion of the NF-κB subunits c-Rel and p65 limited the expression of key type 2 genes, including <em>Il13</em> and <em>Il5</em>, in ILC2s but not in Th2 cells. Genome-wide analysis revealed that the regulatory regions of such genes exist in an open chromatin state in ILC2s, allowing NF-κB binding upon IL-33 stimulation. These regions are less accessible in unstimulated Th2 cells, where NFAT plays a dominant role. Accordingly, p65 deletion impaired ILC2 activation and function during airway inflammation and helminth infection.
