The immunological synapse, a key determinant of T-cell function, is influenced by the CD58-CD2 axis. The dynamic regulation of CD2 expression on T cells impacts the quality of CAR-mediated immunological synapses, affecting CAR-T-cell functional outcomes and differentiation. Our study demonstrated that CD2 expression levels are closely linked to the quality of immunological synapses formed by CAR-T cells and their antitumor potency. Exogenous CD2 supplementation enhances the ability of CAR-T cells to form high-quality synapses, reduces T-cell exhaustion, and increases sustained antitumor efficacy. Additionally, ectopic CD2 expression increases CAR-T-cell sensitivity to low-density antigens. Thus, replenishing CD2 in CAR-T cells is a promising strategy to increase the therapeutic efficacy of CAR-T-cell therapy.","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":"22 8","pages":"935-948"},"PeriodicalIF":19.8,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12311108/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most chronic liver diseases shift toward inflammation over time. Understanding and intercepting the crosstalk between various immune cells and liver tissue is crucial, as it is often the rate-limiting factor in preclinical drug development. Owing to significant interspecies differences in liver immunology, human models, such as classical cocultures or organogenesis-inspired liver organoids with immune compartments, are becoming essential for advancing the field. Therefore, this review evaluates human-specific models of hepatic-immune crosstalk and assesses a range of models from basic 2D cultures to microphysiological systems (MPSs) and advanced multitissue organoids. It serves as a guide for experimentalists to identify suitable approaches. For example, traditional cocultures offer robustness, reductionist approaches, and modularity but have limited spatial fidelity and cell heterogeneity. In contrast, multitissue organoids inspired by mammalian ontogeny are created from pluripotent stem cells and integrate multiple tissue niche-constituting cells, which include Kupffer-like cells. In conclusion, this review discusses progress in human liver immunology modeling and highlights limitations and numerous untapped opportunities. These include the potential to model in vitro autoimmunity and more complex myeloid inflammatory responses, incorporating contributions from embryonic tissue and bone marrow. Additionally, future in vitro models may include hard-to-culture populations such as neutrophils.","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":"22 10","pages":"1226-1236"},"PeriodicalIF":19.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41423-025-01312-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144552479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure long-term and broad protection against heterologous virus variants, antigen-specific polyfunctional T cells should be orchestrated with the activation of follicular helper T (TFH) cells and germinal center (GC) B cells. Herein, we suggest a novel engineered nanoadjuvant (SE(Trojan-TLR7/8a)) that enhances the migration of nonexhausted antigen-presenting cells (APCs) into lymph nodes and elicits the activation of TFH cells, the generation of GC B cells, and polyfunctional T cells via multiscale dynamic immunomodulation through squalene nanoemulsion (SE)-mediated macroscopic control of vaccine delivery and Trojan-TLR7/8a-enabled dynamic and sustained activation of APCs at the cellular level. SE(Trojan-TLR7/8a) can be lyophilized, reduce systemic toxicity, and outperform current commercial vaccine adjuvants (Alum or AS03) and mRNA vaccines. SE(Trojan-TLR7/8a) ensures cross-protection against diverse influenza and SARS-CoV-2 variants, providing 100% protection while maintaining a healthy state. SE(Trojan-TLR7/8a) also sustains a potent T-cell response in an aged ferret model of SFTSV infection.

However, aberrant control of Tfh cells also contributes to the generation of self-reactive autoantibodies and promotes autoimmune diseases such as systemic lupus erythematosus (SLE). The mechanisms that control proper Tfh expansion remain unclear. Here, we show that farnesoid X receptor (FXR) is relatively upregulated in Tfh cells. Genetic deletion of Fxr restrains Tfh expansion both at steady state and in pristane-induced lupus. As a consequence of these defects, mice lacking Fxr manifested GC dysfunction and decreased plasma cell and autoantibody production, which alleviated nephritis progression in pristane-induced lupus. Mechanistically, FXR intrinsically regulates cholesterol homeostasis in Tfh cells, which subsequently controls Tfh cell proliferation. Preclinical treatment of wild-type (WT) mice with the clinically approved drug ursodeoxycholic acid (UDCA) to reduce FXR signaling mitigated lupus disease progression by repressing Tfh expansion, the GC reaction and autoantibody production. These findings provide a rationale for exploring FXR as a potential therapeutic target for SLE.","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":"22 8","pages":"889-900"},"PeriodicalIF":19.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144494920","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}

Abnormal NF-κB activation also influences the development and stability of regulatory T cells, contributing to the pathogenesis of autoimmune disorders. Given the critical role of inflammation in promoting oncogenesis, the proinflammatory role of NF-κB is also linked to cancer development. In addition, aberrant NF-κB activation contributes to uncontrolled tumor cell proliferation, survival, metabolism, metastasis, tumor angiogenesis and therapy resistance. These pathological functions of NF-κB highlight its potential as a therapeutic target for both inflammatory diseases and cancer.

Here, we revealed a dynamic immunoregulatory role of dermal white adipose tissue (dWAT) in the progression and resolution of neutrophilic skin inflammation in an imiquimod-induced psoriasis mouse model. During inflammation onset, dWAT repopulates PDGFRA+ preadipocytes (pAds), which secrete CXCL1 and SAA3, attracting and activating CXCR2+ neutrophils. These neutrophils further activate pAds through the IL-1R-NFκB-C/EBPδ pathway, establishing a self-sustaining inflammatory loop. Paradoxically, prolonged IL-1β signaling triggers PPARγ-dependent adipogenesis, transitioning pAds into anti-inflammatory early adipocytes that resolve neutrophilic inflammation via lipid mediators. Inhibition of adipogenesis, via pharmacological or genetic inhibition of PPARγ, disrupts the formation of early adipocytes, prevents neutrophil regression, and exacerbates inflammation. Analysis of human psoriatic cells revealed a C/EBPδ+ dermal fibroblast (dFB) subpopulation enriched with preadipocytes, the IL-1 pathway, and inflammatory gene signatures. Furthermore, transcriptomic analyses revealed a negative correlation between the neutrophil-related inflammatory response and the dermal lipogenesis response in generalized pustular psoriasis. Together, our findings reveal the dual role of dWAT: PDGFRA+ pAds initiate inflammation via CXCL1/IL-1β crosstalk with neutrophils, whereas PPARγ-driven adipogenesis resolves this process through lipid mediators. This work establishes dWAT as a critical immunomodulatory hub and proposes adipogenic reprogramming of proinflammatory fibroblasts or topical delivery of early adipocyte lipids as innovative therapies for neutrophil-driven skin diseases, such as psoriasis and ulcers. Our study uncovers a dynamic immunoregulatory role of dermal white adipose tissue (dWAT) in the progression and resolution of neutrophilic skin inflammation in an imiquimod-induced psoriatic mouse model. Initially, dWAT undergoes lipolysis and expands preadipocytes (pAds) secreting CXCL1/SAA3 to recruit neutrophils, which amplify inflammation via IL1β and activate pAds through the IL1-NFκB-C/EBPδ pathway. Prolonged IL1β exposure triggers PPARγ-dependent differentiation of pAds into early adipocytes, producing anti-inflammatory lipids that resolve neutrophilic inflammation. We also observed a negative correlation between neutrophil-related inflammatory response with dermal lipogenesis is also observed in human psoriasis. These findings highlight dWAT as an immunomodulatory hub, suggesting adipogenic reprogramming or lipid delivery as novel psoriasis therapies.","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":"22 8","pages":"901-917"},"PeriodicalIF":19.8,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144474082","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}
