The most common form of CTCL, mycosis fungoides, can be difficult to diagnose, resulting in treatment delay. We performed single-cell and spatial transcriptomics analysis of skin from patients with mycosis fungoides-type CTCL and an integrated comparative analysis with human skin cell atlas datasets from healthy and inflamed skin. We revealed the co-optation of T helper 2 (TH2) cell-immune gene programs by malignant CTCL cells and modeling of the tumor microenvironment to support their survival. We identified MHC-II+ fibroblasts and dendritic cells that can maintain TH2 cell-like tumor cells. CTCL tumor cells are spatially associated with B cells, forming tertiary lymphoid structure-like aggregates. Finally, we validated the enrichment of B cells in CTCL and its association with disease progression across three independent patient cohorts. Our findings provide diagnostic aids, potential biomarkers for disease staging and therapeutic strategies for CTCL.

However, because the immune system also has the capacity to self-regulate through anti-inflammatory mechanisms that drive the resolution of inflammation, it might promote pain resolution and prevention. Here, we describe how immune cell-derived cytokines can act directly on sensory neurons to inhibit pain hypersensitivity and how immune-derived endogenous opioids promote analgesia. We also discuss how immune cells support healthy tissue innervation by clearing debris after nerve injury, protecting against axon retraction from target tissues and enhancing regeneration, preventing the development of chronic neuropathic pain. Finally, we review the accumulating evidence that manipulating immune activity positively alters somatosensation, albeit with currently unclear molecular and cellular mechanisms. Exploration of immune-mediated analgesia and pain prevention could, therefore, be important for the development of novel immune therapies for the treatment of clinical pain states. Woolf and colleagues review the current evidence that immune cells could promote pain resolution and prevention through direct effects on sensory neurons and through maintaining healthy tissue innervation.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"25 12","pages":"2200-2208"},"PeriodicalIF":27.7,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142598038","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}

Exhausted T (Tex) cells are characterized by upregulation of coinhibitory molecules and reduced polyfunctionality. T cells in the TME experience an immunosuppressive metabolic environment via reduced levels of nutrients and oxygen and a buildup of lactic acid. Here we show that terminally Tex cells uniquely upregulate Slc16a11, which encodes monocarboxylate transporter 11 (MCT11). Conditional deletion of MCT11 in T cells reduced lactic acid uptake by Tex cells and improved their effector function. Targeting MCT11 with an antibody reduced lactate uptake specifically in Tex cells, which, when used therapeutically in tumor-bearing mice, resulted in reduced tumor growth. These data support a model in which Tex cells upregulate MCT11, rendering them sensitive to lactic acid present at high levels in the TME. Here the authors show that high expression of MCT11 is key to the dysfunctionality associated with exhausted CD8+ T cells in tumors. By targeting MCT11, uptake of lactic acid, which is abundant in the tumor, is reduced, resulting in improved effector functions and tumor immunity.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"25 12","pages":"2297-2307"},"PeriodicalIF":27.7,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41590-024-01999-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142596855","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}

Children in Papua New Guinea (PNG) experience profound morbidity from ALRI caused by Streptococcus pneumoniae. As a result of evolutionary divergence, the human PNG population exhibits profound genetic variation and diversity. To address unmet health needs of children in PNG, we tested whether genetic variants increased ALRI morbidity. Whole-exome sequencing of a pilot child cohort identified homozygosity for a novel single-nucleotide variant (SNV) in coenzyme Q6 (COQ6) in cases with ALRI. COQ6 encodes a mitochondrial enzyme essential for biosynthesis of ubiquinone, an electron acceptor in the electron transport chain. A significant association of SNV homozygosity with ALRI was replicated in an independent ALRI cohort (P = 0.036). Mice homozygous for homologous mouse variant Coq6 exhibited increased mortality after pneumococcal lung infection, confirming causality. Bone marrow chimeric mice further revealed that expression of variant Coq6 in recipient (that is, nonhematopoietic) tissues conferred increased mortality. Variant Coq6 maintained ubiquinone biosynthesis, while accelerating metabolic remodeling after pneumococcal challenge. Identification of this COQ6 variant provides a genetic basis for increased pneumonia susceptibility in PNG and establishes a previously unrecognized role for the enzyme COQ6 in regulating inflammatory-mediated metabolic remodeling. Morley, Pomat and colleagues identify a homozygous mutation in COQ6 in an indigenous population of Papua New Guinea. This allele predisposes children to increased risk of acute lower respiratory infections in response to Streptococcus pneumoniae. This sensitivity is recapitulated in Coq6DY mice in the nonhematopoietic compartment.","PeriodicalId":19032,"journal":{"name":"Nature Immunology","volume":"25 12","pages":"2247-2258"},"PeriodicalIF":27.7,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574514","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}
