This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

This study demonstrated that antigens from the skin bacterium Staphylococcus epidermidis can stimulate CD8+ T cells, which in turn enhance wound healing.

This study found that thyroid-stimulating hormone receptors are functionally expressed in various skin cells, implying potential physiological and pathological roles in skin, especially in conditions like autoimmune diseases.

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 haploinsufficiency of SPINK5 can lead to Netherton syndrome when a single null mutation combines with homozygous G1258A polymorphisms, suggesting it acts as a genuine mutation affecting LEKTI function.

This study found that clusters of mRNAs and lncRNAs in the peripheral blood of PCOS patients were aberrantly expressed, and certain lncRNA-mRNA pairs in the chemokine signaling pathway may be genetically related to PCOS.

This study analyzed gene expression data to identify key genes involved in severe forms of alopecia areata, discovering four immune monitoring genes (LGR5, SHISA2, HOXC13, S100A3) with potential for early diagnosis and better understanding of the disease's biological mechanisms.

This study found that expression of GDNF and GFR α-1 proteins in human skin decreases with age, particularly in the epidermis, suggesting that their signaling pathways may be altered as people grow older.

This review discusses the advancements needed for gene therapy to become commonly used in dermatology and reports no new clinical results.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

This study suggests that the newly characterized sebocytic progenitor cells HSGC1 and HSGC2 from different skin sites may have proliferative and differentiating potential in response to DHT.

This study identified a shared gene signature in scarring alopecia subtypes, with increased mast cell presence, suggesting similar treatment approaches may be effective across these hair loss disorders.

This study found that while CBD did not change gene expression including β-catenin in hair follicles, it restored decreased β-catenin expression in dermal papilla cells affected by testosterone or PMA, suggesting a potential modulating function on alopecia.

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 suggests that human hair follicles may actively suppress natural killer cells, which contrasts with the observed defects in NK cell regulation in alopecia areata.

Farudodstat may effectively treat alopecia areata without harmful side effects.

This study suggests that SOCS3 treatment may effectively inhibit alopecia areata by suppressing CD8+ T cell activity and IFN-γ production.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This study found that interleukin-12 signals play a role in hair follicle immune privilege collapse in ex vivo alopecia areata models, and a TYK2 inhibitor may help prevent or reverse this process.

This study found that pediatric alopecia areata patients with atopic predisposition showed heightened immune and inflammatory responses, including significant immune cell infiltration, compared to adults and healthy controls.

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 analysis reports that hepatitis B surface protein antigen exposure is associated with an increased risk of alopecia areata.

In this study, gene expression analysis of plucked hair follicles from scalp lesions was sufficient to differentiate chronic discoid lupus erythematosus from psoriasis and healthy controls, suggesting a non-invasive diagnostic potential.

This review discusses the mechanisms underlying the collapse of hair follicle immune privilege in alopecia areata and emphasizes the importance of therapeutic strategies aimed at restoring immune tolerance.

IL-27 may help prevent hair loss in alopecia areata by promoting immunosuppressive T cells.

This case report describes a nine-year-old girl with juvenile dermatomyositis and alopecia areata, suggesting a possible etiological link between these coexisting immune-mediated diseases, a previously unreported association.

In this study, ritlecitinib treatment for 12 and 24 weeks downregulated immunity-related genes and upregulated hair keratin genes in patients with alopecia areata, correlating with scalp hair regrowth response.

In this study, mouse models with EGFR deficiency showed that disrupted hair follicle cycling leads to increased mast cell numbers and inflammation, suggesting EGFR's role in managing hair cycle transitions and preventing folliculitis.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.
