However, when dysregulated by intrinsic or extrinsic metabolic factors, T cells may contribute to a wide spectrum of diseases, such as cancers and autoimmune diseases. However, the metabolic regulation of T cells remains incompletely understood. Here, we show that MYO1F is required for human and mouse T-cell activation after TCR stimulation and that T-cell-specific Myo1f knockout mice exhibit an increased tumor burden and attenuated EAE severity due to impaired T-cell activation in vivo. Mechanistically, after TCR stimulation, MYO1F is phosphorylated by LCK at tyrosines 607 and 634, which is critical for glyceraldehyde-3-phosphate dehydrogenase (GAPDH) acetylation at Lys84, 86 and 227 mediated by α-TAT1, which is an acetyltransferase, and these processes are important for its activation, cellular glycolysis and thus the effector function of T cells. Importantly, we show that a fusion protein of VAV1-MYO1F, a recurrent peripheral T-cell lymphoma (PTCL)-associated oncogenic protein, promotes hyperacetylation of GAPDH and its activation, which leads to aberrant glycolysis and T-cell proliferation, and that inhibition of the activity of GAPDH significantly limits T-cell activation and proliferation and extends the survival of hVAV1-MYO1F knock-in mice. Moreover, hyperacetylation of GAPDH was confirmed in human PTCL patient samples containing the VAV1-MYO1F gene fusion. Overall, this study revealed not only the mechanisms by which MYO1F regulates T-cell metabolism and VAV1-MYO1F fusion-induced PTCL but also promising therapeutic targets for the treatment of PTCL.</p>","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":" ","pages":""},"PeriodicalIF":21.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142817420","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}

While combining immune checkpoint inhibitors (ICIs) and radiotherapy in patients with pancreatic cancer (PC) has yielded promising clinical results, the addition of an anti-IL-6 receptor (IL-6R) antibody has failed to elicit clinical benefits. Notably, a robust TGFβ-specific immune response at baseline in PC patients treated solely with ICIs and radiotherapy correlated with improved survival. Recent preclinical studies demonstrated the efficacy of a TGFβ-based immune modulatory vaccine in controlling PC tumor growth, underscoring the important role of TGFβ-specific immunity in PC. Here, we explored the importance of IL-6 for TGFβ-specific immunity in PC. In a murine model of PC, coadministration of the TGFβ-based immune modulatory vaccine with an anti-IL-6R antibody rendered the vaccine ineffective. IL-6R blockade hampered the development of vaccine-induced T-cells and tumoral T-cell infiltration. Furthermore, it impaired the myeloid population, resulting in increased tumor-associated macrophage infiltration and an enhanced immunosuppressive phenotype. In PC patients, in contrast to those receiving only ICIs and radiotherapy, robust TGFβ-specific T-cell responses at baseline did not correlate with improved survival in patients receiving ICIs, radiotherapy and IL-6R blockade. Peripheral blood immunophenotyping revealed that IL-6R blockade altered the T-cell and monocytic compartments, which was consistent with the findings in the murine model. Our data suggest that the antitumor efficacy of TGFβ-specific T cells in PC depends on the presence of IL-6 within the tumor. Consequently, caution should be exercised when employing IL-6R blockade in patients receiving cancer immunotherapy.</p>","PeriodicalId":9950,"journal":{"name":"Cellular &Molecular Immunology","volume":" ","pages":""},"PeriodicalIF":21.8,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142799561","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}

The potent killing machinery necessary for immune responses to pathogens can easily lead to collateral damage to host tissues when inappropriately controlled. Furthermore, some subtypes of neutrophils are potent pathogen killers, whereas others are immunosuppressive or can aid in tissue healing. Finally, in tumor immunology, many examples of both protumorigenic and antitumorigenic properties of neutrophils have been described. This has important consequences for cancer therapy, as targeting neutrophils can lead to either suppressed or stimulated antitumor responses.

In this study, we investigated the role of ILC2s in EoE pathogenesis. We observed an abundance of KLRG1⁺ ILC2s in the esophagi of healthy mice, with their numbers significantly increasing in murine EoE models and humans. Using a murine EoE model, we demonstrated the recapitulation of EoE-associated features, including basal-cell hyperproliferation, epithelial thickening, and eosinophilia.

Although it is widely believed that SLE originates from immune cell dysregulation, the etiology of SLE is not yet clear. Here, we propose a new theory in which SLE can be directly initiated by molecular alterations in keratinocytes rather than immune cells. We found that the level of peroxisome proliferator-activated receptor gamma (PPARγ) is substantially reduced in the skin lesions of patients, and replicating this reduction in mice led to rapid disease onset with multiple hallmarks of SLE. As PPARγ decreases in keratinocytes, which is accompanied by increased occupancy of interferon regulatory factor 3 at the type I interferon locus, dendritic cells (DCs) are recruited to the epidermis and are activated by keratinocyte-secreted type I interferon. These activated DCs migrate to local draining lymph nodes, where they activate CD4⁺ T cells in a non-MHC II-dependent manner, promoting their differentiation into effector T cells and thus contributing to disease onset. Our study revealed that the dysregulation of keratinocytes can be a pathogenic driver of SLE and describes a new mouse model that mimics human SLE.

O-GlcNAcylation is a dynamic and reversible posttranslational modification of nuclear and cytoplasmic proteins that regulates various protein functions, including DNA-binding affinity and protein-protein interactions. However, the effects of O-GlcNAcylation on proteins involved in V(D)J recombination remain largely unknown. To elucidate this relationship, we downregulated O-GlcNAcylation in a mouse model by administering an O-GlcNAc inhibitor or restricting the consumption of a regular diet. Interestingly, the inhibition of O-GlcNAcylation in mice severely impaired Ig heavy-chain (IgH) gene rearrangement. We identified several factors crucial for V(D)J recombination, including YY1, CTCF, SMC1, and SMC3, as direct targets of O-GlcNAc modification. Importantly, O-GlcNAcylation regulates the physical interaction between SMC1 and SMC3 and the DNA-binding patterns of YY1 at the IgH gene locus. Moreover, O-GlcNAc inhibition downregulated DDX5 protein expression, affecting the functional association of CTCF with its DNA-binding sites at the IgH locus. Our results showed that locus contraction and long-range interactions throughout the IgH locus are disrupted in a manner dependent on the cellular O-GlcNAc level.
