This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This study found that ILC1-like cells can induce alopecia areata in healthy human hair follicles, suggesting that these cells might be a therapeutic target in AA management.

This study found that NIMP-R14-conjugated nanoparticles, loaded with roflumilast, effectively targeted neutrophils to reduce inflammation and improve symptoms in a mouse model of psoriasiform dermatitis, suggesting potential for targeted therapy in autoimmune skin diseases.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

This study found that IL18 signaling plays a crucial role in the homing and retention of mature regulatory T cells in the mouse thymus, primarily by upregulating the chemokine receptor CCR6.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This review discusses the role and mechanisms of unconventional lymphocytes in promoting tissue repair and maintaining mucosal barrier integrity in the skin, gut, and lungs, but reports no new findings.

This study demonstrated that the human thymus contains clonogenic thymic epithelial cells capable of self-renewal and maintaining a thymic phenotype in a specific culture system.

This study found that NK and CD8+ T cell infiltration may drive inflammation in androgenetic alopecia, suggesting that targeting IL-15 signaling could offer a new therapeutic approach for hair regeneration.

This study identified a subtype of itch-sensing neurons in mice, which express Ret and somatostatin, and found that their ablation reduces scratching induced by certain pruritogens.

This study found that monocytes/macrophages with a pro-inflammatory M1-like phenotype may play a crucial role in the pathogenesis of hidradenitis suppurativa, suggesting potential therapeutic targets.

This study provides a detailed cellular atlas of cutaneous squamous cell carcinoma, indicating that different fibroblast subtypes play roles in tumor progression and suppression, with potential biomarkers identified for HPV-related tumor growth.

This study found that mrp/plf-mRNA expression in murine skin increases in response to different tumor promoters, suggesting its potential as a short-term biomarker for chemical carcinogenesis.

This study found that multipotent, nestin-expressing stem cells from the upper part of hair follicles can proliferate significantly and differentiate into various cell types, showing potential for nerve and spinal cord repair.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

This study observed that anti-multiple nuclear dots antibodies, typically markers for primary biliary cirrhosis, were also present in patients with various autoimmune and connective tissue diseases, without correlating to disease activity or specific skin features.

This study suggests that M2 macrophages play a key role in promoting wound-induced hair neogenesis in mice by producing growth factors like Igf1 and Fgf2.

In this study, researchers analyzed skin tumors from patients with CYLD cutaneous syndrome and found that loss of CYLD function is linked to changes in cellular signaling pathways, particularly NF-κB signaling, and leads to increased secretion of specific extracellular matrix proteins.

Certain immune cells in atopic dermatitis skin could be targeted for treatment.

This study reports a case of a patient with neuromyelitis optica spectrum disorders treated with eculizumab who developed fatal sepsis after insulin resistance emerged.

This study observed that cell aggregates derived from mouse skin and lung tissues may aid in hair follicle regeneration when transplanted into skin defects of immunodeficient mice.

This study identified altered mRNA and lncRNA profiles in NS scalp tissues, highlighting CDKN2AIP as a downregulated gene involved in a ceRNA network.

In this study of C3H/HeJ mice, researchers observed that alopecia areata is associated with the expansion of exhausted-memory CD8 T cells in multiple organs, with autoreactive activation not fully explained by known mechanisms, shedding light on the immunological dynamics underlying the condition.

This research explored the roles of various T cell types in chronic alopecia areata, finding that increased severity of lesions and hair loss may be linked to decreased lesional Foxp3+ Tregs, with a notable role for IL-17 and Th17 lymphocytes in the pathological process.

This study examined monoclonal antibodies LT-1, LT-2, and LT-7, finding they can effectively detect certain antigens on T and B cells involved in various lymphoproliferative diseases, aiding in the diagnosis of both acute and chronic lymphoid neoplasias.

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

Arg1+ macrophages may play a role in causing alopecia areata.

This study found that the combination of TTNPB and CHIR99021 enhanced the derivation of highly advanced neural stem cells from human pluripotent stem cells, with improved chromatin accessibility and neuroectodermal gene expression, and these cells successfully engrafted in rat hippocampi to ameliorate depression-like symptoms.

In this study, researchers created a detailed human skin cell atlas by analyzing over 700,000 cells, finding that disrupted communication among specific immune and stromal cell subsets may play a key role in initiating and sustaining chronic skin inflammation in atopic dermatitis.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.
