However, clinical use is challenged by envelope diversity and rapid viral escape. Here, we performed single B cell profiling of 32 top HIV-1 elite neutralizers to identify broadly neutralizing antibodies with highest antiviral activity. From 831 expressed monoclonal antibodies, we identified 04_A06, a V<sub>H</sub>1-2-encoded broadly neutralizing antibody to the CD4 binding site with remarkable breadth and potency against multiclade pseudovirus panels (geometric mean half-maximal inhibitory concentration = 0.059 µg ml<sup>-1</sup>, breadth = 98.5%, 332 strains). Moreover, 04_A06 was not susceptible to classic CD4 binding site escape variants and maintained full viral suppression in HIV-1-infected humanized mice. Structural analyses revealed an unusually long 11-amino-acid heavy chain insertion that facilitates interprotomer contacts with highly conserved residues on the adjacent gp120 protomer. Finally, 04_A06 demonstrated high activity against contemporaneously circulating viruses from the Antibody-Mediated Prevention trials (geometric mean half-maximal inhibitory concentration = 0.082 µg ml<sup>-1</sup>, breadth = 98.4%, 191 virus strains), and in silico modeling for 04_A06LS predicted prevention efficacy of >93%. Thus, 04_A06 will provide unique opportunities for effective treatment and prevention of HIV-1 infection.</p>","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":" ","pages":""},"PeriodicalIF":27.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145239195","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 provide a high-resolution spatial kidney cell atlas of 57 samples from patients with RPGN (ANCA-associated GN, lupus nephritis and anti-glomerular basement membrane-GN) to characterize the cell signaling pathways in glomerular crescent development. Early platelet-derived growth factor (PDGF) signaling from epithelial and mesangial cells caused PEC activation and proliferation in glomerular crescents, whereas later transforming growth factor (TGF)-β signaling from macrophages, T cells and epithelial and mesangial cells triggered expression of extracellular matrix components in PECs associated with glomerulosclerosis and disease progression. These findings were similar across the different GNs and were functionally validated in experimental GN by PDGF and TGFβ blockade. These results highlight a spatiotemporally conserved progression program into glomerular crescents and sclerosis and indicate new treatment options for autoimmune kidney disease.</p>","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":" ","pages":""},"PeriodicalIF":27.6,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145200432","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 show that CA-enriched DNA fragments resulting from DNA-damaging chemotherapy in MSH2-low tumors preferentially bind cGAS with strong affinity and form biomolecular condensates by phase separation in the cytoplasm, resulting in antitumor immunity. However, classical CA-poor DNAs released from MSH2-high tumor cells engage AIM2, resulting in immunosuppression by upregulating PD-L1 and IDO. Intratumoral administration of CA-rich DNA fragments enhanced antitumor immunity in syngrafted PyMT tumors. Clinically, CA-rich DNA abundance in breast cancer following chemotherapy was associated with increased tumor-antigen-reactive T cells and better chemotherapeutic responses. Therefore, different tumor DNA fragments can trigger opposing immune responses depending on their preference for differential sensors. This study highlights another mechanistic link between genome instability and immune modulation and the therapeutic potential of CA-rich DNAs to enhance antitumor immunity.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"28 1","pages":""},"PeriodicalIF":30.5,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189324","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}
