However, it is unknown whether keratinocytes contribute to touch-evoked pain and hypersensitivity after tissue injury. Here, we used a mouse model of paclitaxel treatment to determine the extent to which keratinocyte activity contributes to the severe neuropathic pain that accompanies chemotherapy. We found that keratinocyte inhibition by either optogenetic or chemogenetic methods largely alleviated paclitaxel-induced mechanical hypersensitivity across acute and persistent time points from 2 days through 3 weeks. Furthermore, we found that paclitaxel exposure sensitized mouse and human keratinocytes to mechanical stimulation and enhanced currents of PIEZO1, a mechanosensitive channel highly expressed in keratinocytes. Deletion of PIEZO1 from keratinocytes alleviated paclitaxel-induced mechanical hypersensitivity in mice. These findings suggest that nonneuronal cutaneous cells contribute substantially to neuropathic pain and pave the way for the development of new pain relief strategies that target epidermal keratinocytes and PIEZO1.","PeriodicalId":21580,"journal":{"name":"Science Translational Medicine","volume":"9 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809806","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}

Sensory neurons actively suppress mast cell activation through the regulated release of glutamate, resulting in reduced expression of <jats:italic>Mrgprb2</jats:italic> as well as genes associated with proteins found in mast cell granules. To determine whether exogenous glutamate receptor agonism could suppress mast cell function, we determined that mast cells have relatively selective expression of the glutamate receptor ionotropic, kainate 2 (GluK2). A GluK2-specific agonist, SYM2081, effectively inhibited mast cell degranulation in response to MrgprB2 agonism in both murine mast cells and human skin explants in vitro as well as in vivo after both intradermal and topical administration of SYM2081 to mice. Analyses of transcriptomic datasets from SYM2081-treated mast cells using standard differential expression approaches and an interpretable machine learning technique revealed a previously unrecognized cellular program coordinately regulated by GluK2 agonism. GluK2 agonism suppressed the expression of <jats:italic>Mrgprb2</jats:italic> and genes associated with mast cell proliferation. Suppression of mast cell proliferation by SYM2081 exposure was confirmed on the basis of reduced Ki-67 expression and BrdU incorporation in vitro and in vivo. Last, pretreatment with SYM2081 reduced skin inflammation in murine models of dermatitis and rosacea. Thus, agonism of GluK2 represents a promising approach to suppress mast cell activation and may prove beneficial as therapy for inflammatory diseases in which mast cell activation is pathogenic.","PeriodicalId":21580,"journal":{"name":"Science Translational Medicine","volume":"28 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809861","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}

This results in an increased susceptibility to cancers, infections, and autoimmunity and in reduced vaccine efficacy. Here, we identified that the receptor activator of nuclear factor κB (RANK)–RANK ligand (RANKL) axis in the thymus is altered during aging. Using a conditional transgenic mouse model, we demonstrated that endothelial cells depend on RANK signaling for their cellularity and functional maturation. Decreased RANKL availability during aging resulted in a decline in cellularity and function of both endothelial cells and thymic epithelial cells, contributing to thymic involution. We then found that, whereas RANKL neutralization in young mice mimicked thymic involution, exogenous RANKL treatment in aged mice restored thymic architecture as well as endothelial cell and epithelial cell abundance and functional properties. Consequently, RANKL improved T cell progenitor homing to the thymus and boosted T cell production. This cascade of events resulted in peripheral T cell renewal and effective antitumor and vaccine responses in aged mice. Furthermore, we conducted a proof-of-concept study that showed that RANKL stimulates endothelial cells and epithelial cells in human thymic organocultures. Overall, our findings suggest that targeting the RANK-RANKL axis through exogenous RANKL administration could represent a therapeutic strategy to rejuvenate thymic function and improve T cell immunity during aging.","PeriodicalId":21580,"journal":{"name":"Science Translational Medicine","volume":"74 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142776505","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}

Although microglial activation precedes neuronal loss, it remains elusive whether loss of the membrane protein NPC1 in microglia actively contributes to NPC pathology. In a mouse model with depletion of NPC1 in myeloid cells, we report severe alterations in microglial lipidomic profiles, including the enrichment of bis(monoacylglycero)phosphate, increased cholesterol, and a decrease in cholesteryl esters. Lipid dyshomeostasis was associated with microglial hyperactivity, marked by an increase in translocator protein 18 kDa (TSPO). These hyperactive microglia initiated a pathological cascade resembling NPC-like phenotypes, including a shortened life span, motor impairments, astrogliosis, neuroaxonal pathology, and increased neurofilament light chain (NF-L), a neuronal injury biomarker. As observed in the mouse model, patients with NPC showed increased NF-L in the blood and microglial hyperactivity, as visualized by TSPO-PET imaging.

However, most studies addressing angiogenesis and cognitive impairment focus on model organisms. To test the relevance of angiogenesis to human cognitive aging, we evaluated associations of circulating blood markers of angiogenesis with brain aging trajectories in a pooled two-center sample from deeply phenotyped longitudinal human cohorts (<i>n</i> = 435; female = 207, age = 74 ± 9) using cognitive assessments, biospecimens, structural brain imaging, and clinical data. Blood markers included ligands involved in angiogenesis and vascular function such as basic fibroblast growth factor (bFGF), members of the vascular endothelial growth factor family (VEGFA, VEGFB, and VEGFC), and placental growth factor (PlGF), in addition to their receptors VEGF receptor 1 (VEGFR1) and tyrosine kinase with immunoglobulin and EGF homology domain 2 (Tie2). Machine learning and traditional statistics revealed sexually dimorphic associations of plasma angiogenic growth factors with brain aging outcomes, including executive function and gray matter atrophy. Specifically, markers of angiogenesis were associated with higher executive function and less brain atrophy in younger women (not men), a directionality of association that reversed around age 75. Higher concentrations of bFGF, known for pleiotropic effects on multiple cell types, predicted favorable cognitive trajectories in both women and men. An independent sample from a multicenter dataset (MarkVCID; <i>n</i> = 80; female = 30, age = 73 ± 9) was used to externally validate these findings.
