This commentary reports the first case of small fiber neuropathy, mast cell activation syndrome, and pericarditis following mRNA-based SARS-CoV-2 vaccination in a previously healthy 66-year-old woman.

This study reviewed the role of inflammasomes in autoimmune skin diseases, highlighting their contribution to the pathogenesis of conditions such as vitiligo, alopecia areata, and psoriasis, and suggesting that targeting inflammasome dysregulation may offer new therapeutic options.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

In this study, researchers found that correcting the HGPS mutation with Adenine base editing partially rescued accelerated skin cell differentiation and reduced cell death in patient-derived stem cells.

The study found that Anagen grow, a herbal serum, promotes hair growth elongation and may inhibit the alpha reductase enzyme, suggesting it as a safe, effective alternative to finasteride and beneficial alongside minoxidil for reducing scalp dryness.

In this in vitro study, pretreatment with Dead Sea water and saline magnetized water reduced UVB-induced DNA damage and inflammation markers in human keratinocyte cells, primarily through autophagy activation, suggesting potential use in topical products to prevent skin damage from UV exposure.

Immune cells boost stem cell activity in hairy moles, causing more hair growth.

In cashmere goats, this study found that reducing miR-361-5p levels activates secondary hair follicle stem cells by upregulating the FOXM1 gene, which in turn stimulates the Wnt/β-catenin pathway, crucial for cashmere fiber morphogenesis.

This study found that stimulating toll-like receptor 5 via mucosal delivery of a flagellin-containing fusion protein effectively extended lifespan and enhanced healthspan in mice, including improved bone density and cognitive capacity.

This study found that in Hutchinson–Gilford progeria syndrome, iPSCs committed to the keratinocyte lineage faster than normal cells, with LEF1 expression reduced and a partial rescue of the phenotype achieved through adenine base editing.

In this study, azelaic acid was found to enhance UVB protection in bulge cells and, when combined with minoxidil, may promote hair growth through increased Sonic hedgehog protein expression in hair follicles.

This study found that aging mice with an epidermal deletion of DNA methyltransferase 1 had a reduced number of hair follicles, due to decreased stem cell activation probability.

This study provides insight into AR-mediated gene activation and the molecular mechanisms of prostate cancer progression and drug resistance, identifying potential avenues for developing new therapies.

D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

This study observed that DMAP scaffolds in a full-thickness wound model promote dermal appendage regeneration by activating humoral immunity, specifically through B cell activation and antibody production, even when adaptive immune cells' infiltration is restricted.

This study found that activating BMP signaling in rodent and primate models significantly promotes nail and digit regeneration after amputation by enhancing the role of specific nail stem cells, though extreme proximal amputation only permitted partial regeneration without bone reconstruction.

This study identifies macrophage-mediated immune signaling as a crucial factor in activating hair follicle stem cells and promoting hair regeneration, offering a new model for testing regenerative therapies for alopecia.

This study found that activating hair follicle resident T cells in a human organ culture can induce an alopecia areata-like immune response, and that the drug farudodstat partially reduced this effect.

In this study, topical latanoprost acid applied daily for 6 months increased hair count and improved trichoscopic markers among women with hair loss, suggesting its potential for treating female androgenetic alopecia, particularly at a 0.05% concentration.

In this study, researchers developed EPO-derived peptides that enhanced hair growth by stimulating dermal papilla cells and increasing IGF-1 expression without triggering systemic erythropoietic effects in tested models, indicating a promising approach for treating hair loss.

This study found that multiple vitamins, including B6, increased the number of growing follicles in newborn mouse ovaries in vitro. VB6 promoted primordial follicle activation via the PI3K/Akt signaling pathway in both cultured mouse and human ovarian tissues.

AMP-303 injections can increase hair growth in androgenetic alopecia with minimal side effects.

This review discusses recent advances in hair regeneration strategies, including mechanical stimulation and complementary therapies like MSC transplantation and platelet-rich plasma, and reports no new clinical results.

This study found that HPD is a potent activator of hair follicle regeneration, surpassing the efficacy of conventional minoxidil treatment by modulating Wnt/β-catenin signaling and enhancing follicular proliferation, indicating its potential as a non-invasive hair restoration therapy.

In this study using C57BL/6 mice, the researchers observed that combining minoxidil with exosomes and DNA polynucleotides improved hair follicle density and promoted gene expression linked to hair growth, suggesting enhanced hair growth potential over minoxidil alone.

PRP preparation partially activates platelets, causing varied growth factor release.

This study found that activating autophagy in hair follicle stem cells can promote hair growth by shifting their metabolism to glycolysis, while inhibiting it led to delayed hair cycle progression.

In this study, researchers found that topical application of the diabetes medication Sitagliptin in mice accelerates hair follicle regeneration and reduces fibrosis, suggesting it could be repurposed to treat hair loss conditions like alopecia.

This study found that the dermal sheath smooth muscle regulates hair follicle progenitor cell death during hair regression through mechanical signaling of the TGF-β pathway.
