In this study, activating TRPV1 nociceptors in mice skin stimulated dormant hair follicles and promoted hair growth through a mechanism involving dermal macrophages, fibroblasts, and neuropeptides, highlighting a new role for nociceptors in tissue recovery after injury.

In this study, researchers observed significantly higher CD8+ T cell levels in Iraqi patients with Alopecia areata compared to healthy controls, alongside concluding that the condition is more prevalent in men.

This study found that Th22 cells and their cytokine IL-22 may play an important role in the pathogenesis of systemic lupus erythematosus and could serve as bioindicators for monitoring disease severity.

This study found that mesenchymal cells from different organs exhibit substantial heterogeneity, with thymic mesenchymal cells particularly adapted for interacting with epithelial and hematolymphoid cells in high-apoptosis environments.

In this study, VD(3) pretreatment increased hair follicle formation in a rat model by promoting dermal papilla cell differentiation, suggesting potential for hair regeneration therapy.

In this study, researchers reported that IL-17C plays a key pro-inflammatory role in human skin diseases and may be a promising therapeutic target for inflammatory skin conditions.

This study suggests that IL-17 may play a more significant role than IFN-γ in the pathogenesis of chronic alopecia areata, with increasing severity linked to Th17 lymphocytes and cytotoxic T lymphocyte infiltration.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This study found that over-expression of thymosin beta-4 in transgenic mice accelerated wound healing and hair growth, but did not affect tumor progression despite stimulating tumor metastasis.

This study used cryo-electron microscopy to reveal the structural mechanisms by which TRPV6 and TRPV3 ion channels open, close, and are regulated, providing insights for potential future research.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.

This review discusses potential new drug treatment strategies for alopecia areata based on genome-wide association study findings, but it reports no new clinical results.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This study found that alopecia areata patients who responded poorly to topical immunotherapy had impaired peripheral blood mononuclear cell responses to T-cell stimulants.

This research developed new in vitro models for high-throughput screening of drugs that could protect or restore immune privilege in hair follicles, finding that Tofacitinib was effective in preventing inflammation-related marker upregulation, while Tacrolimus and αMSH worked specifically in outer root sheath keratinocytes.

In a mouse model of peripheral vascular disease, this study found that recombinant thymosin β4 treatment increased expression levels of certain proteins, promoting angiogenesis.

This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.

This study identified a novel G207E STING mutation causing a distinct phenotype involving alopecia, photosensitivity, and thyroid dysfunction, and suggests that common polymorphisms in TMEM173 and IFIH1 may influence disease presentation.

This study found that higher serum CXCL10 levels may predict the progression of non-segmental vitiligo, especially in patients also suffering from autoimmune thyroid disease and/or alopecia areata.

This study discovered that the gene Tfap2b identifies a melanocyte stem cell population in zebrafish, essential for regenerating melanocytes with multi-fate potential into adult pigment cells.

This study documented distinct expression patterns of stem cell markers LGR5 and LGR6 in various human skin tumors, highlighting differences in their potential roles and contributions to tumor development.

CTP-543 is generally safe for treating alopecia areata.

This study found that hair follicles may provide a safe space for tumor cells in mice, suggesting a potential target for cancer prevention during the dormant phase of tumor development.

This case report details an occurrence of Vogt-Koyanagi-Harada disease during pegylated interferon-α2b and ribavirin therapy for chronic hepatitis C.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

This study suggests that autoimmune dysregulation involving HLA-DR+ T and NK cell subsets may contribute to severe patchy alopecia areata and alopecia universalis, with normalization seen after betamethasone treatment.

This study found that three protocols for generating Titan cells in vitro from Candida neoformans vary in their kinetics and transcriptomic profiles, pointing to differences which could impact further research.

This study reviews potential immune targets within hair follicles in alopecia areata, suggesting they may be associated with keratinocytes or melanocytes, and notes possible induction triggers like viruses and infections.

This study found that a single dose of TRP significantly reduced the number of UV-B-induced actinic keratosis lesions in a mouse model and was associated with improved skin histology and minimal side effects.
