In this experimental study, laser irradiation significantly altered the gene expression of cytokines in cultured human T-cell lymphocytes, suggesting that such laser light may photobiomodulate cytokine production in vitro.

This research highlights that JAK inhibitors, such as baricitinib, may effectively reverse symptoms of alopecia areata by targeting specific immune pathways, though safety and efficacy require further investigation.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This study reported that CCT oligodeoxynucleotide induced patchy hair loss in male mice with specific genetic traits, suggesting gender and genetic preferences in immune response.

This study identified at least four distinct fibroblast populations in adult human skin, each with unique functional properties, suggesting potential therapeutic applications for wound healing and fibrosis-related diseases.

This review evaluates the role of the nuclear receptor PPAR- in skin diseases, highlighting its regulation of inflammation, lipid metabolism, and immune response, and suggests that PPAR-agonists could be promising therapies for conditions like psoriasis and atopic dermatitis.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.

This study identified somatostatin as a potential secretory factor contributing to the immune privilege of human hair follicles.

This study identifies substance P, TNFα, and IFNγ as novel regulators of prolactin and its receptor expression in human skin, suggesting intracutaneous prolactin is not controlled by dopamine.

This study found that anthralin and mechlorethamine were the most effective therapies among those tested in AA-affected rodent models, providing a basis for further analysis of their mechanisms in Alopecia Areata.

This study found that vitamin D receptor expression is associated with proliferating keratinocytes, while retinoid X receptor α is linked to differentiating keratinocytes, suggesting differential targeting by vitamin D metabolites.

This study found that antroquinonol inhibited CD8+ T cell proliferation and reduced proinflammatory cytokine secretion in vitro, while also ameliorating H2O2-induced depigmentation and resisting reductions in hair follicle length, skin thickness, and tyrosinase expression in mice.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

This review discusses immune privilege in anagen hair follicles and its collapse in alopecia areata, emphasizing the importance of restoring this function for effective management and disease relapse prevention.

In this study, repeated pregnancies in a murine model of systemic lupus erythematosus altered skin inflammation and cytokine expression but worsened kidney function and survival compared to controls.

In this study, researchers observed that a topical gel containing 20% hypoxia mesenchymal stem cell secretome significantly reduced IL-15 and IFN-γ mRNA expression and baldness by 60% in male Wistar rats with fluconazole-related alopecia.

This study found that topical ginsenoside Rg1 may protect skin from UVB-induced damage in mice by reducing pathological changes and modulating cytokine mRNA expression associated with inflammation and immune response.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.

This study suggests that the neuropeptide CGRP may protect against, but not restore, IFNγ-induced collapse of hair follicle immune privilege in alopecia areata.

This review explores epidermolysis bullosa simplex subtypes caused by mutations in KRT5 or KRT14 and summarizes gene expression patterns and molecular mechanisms, without presenting new experimental results.

This study found that ruxolitinib modulated inflammatory changes and stimulated growth factor signals by blocking the JAK-STAT pathway in an in vitro model of alopecia areata.

This study suggests that lithocholic acid may enhance hair regeneration in alopecia by activating vitamin D receptors in human dermal papilla cells.

This study found that hair follicle-derived mesenchymal stem cells can alleviate pyroptosis and improve ulcerative colitis symptoms in mice, suggesting potential new treatments for the condition.

This study found that immune privilege is preserved in hair follicles of nonsegmental vitiligo patients compared to those with alopecia areata, potentially protecting follicular melanocytes from autoimmune attacks.

This study found that Enz_MoriL, a compound derived from Morus alba L., promotes hair follicle cell proliferation by affecting the Wnt/β-catenin pathway and can counteract an alopecia areata-like condition by suppressing the JAK-STAT signaling in human hair follicle dermal papilla cells.

This study identified molecular differences between dysplastic nevi and common melanocytic nevi, including altered keratinocyte differentiation, increased hair follicle-related molecule expression, and distinct immune microenvironment characteristics in dysplastic nevi.

This study found that neonatal Regulatory T cells are crucial for maintaining PPARγ signaling in hair follicles, which supports melanocyte stem cell function and skin pigmentation during early postnatal development.

This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.

This study found distinct gene expression patterns in the blood of alopecia areata patients, suggesting involvement of immune processes and new pathways like Wnt signaling and apoptosis in disease pathogenesis.
