This review discusses the complexities of hidradenitis suppurativa pathogenesis, highlighting issues with Notch signaling, immune dysregulation, and the role of keratinocytes and ECM, but reports no new clinical results.

This research found that kaempferol, a flavonoid from hair growth-promoting plants, significantly enhanced human dermal papilla cell proliferation and inhibited specific signaling pathways, outperforming minoxidil, with topical application in mice promoting hair growth and thickness, indicating potential as a natural hair loss treatment.

This study found that a TYK2 inhibitor, BMS-986202, may restore immune privilege in hair follicles and promote hair regrowth in a humanized alopecia areata mouse model by inhibiting IL-12-mediated signaling.

This study found that VR1 activation in human hair follicles inhibited hair growth by suppressing proliferation and promoting apoptosis, suggesting VR1 plays an important role in hair growth regulation.

This study found that topical simvastatin induced remission and hair regrowth in a mouse model of alopecia areata, potentially by modulating T cell activity and reducing pro-inflammatory cytokine signaling.

This review summarizes recent research on alopecia areata, highlighting advances in targeted therapies due to improved understanding of its immunopathogenesis, though it reports no new clinical results.

This review discusses recent advances in understanding alopecia areata's disease mechanisms and highlights JAK molecules as promising therapeutic targets, but reports no new clinical results; controlled trials are needed.

This study suggests that frontal fibrosing alopecia is a highly inflammatory disease involving TH1 and JAK-STAT pathways, without reduced hair keratins, highlighting JAK-STAT signaling as a potential therapeutic target.

This study identified CD28, GZMB, and CD1C as key immune regulators in alopecia areata, highlighting CD28 as a potential therapeutic target with a promising safety profile, using a proteome-anchored multi-omics approach to uncover actionable targets for this autoimmune hair-loss disorder.

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.

In this study, bovine milk-derived oligosaccharides were found to increase sebocyte proliferation, lipid content, and inflammatory mediator synthesis through the mTORC1 pathway, potentially contributing to milk-based inflammation in sebocytes.
