Blocking a protein called prostaglandin D2 might help treat hair loss.

This study identified CXXC5 as a key mediator of hair loss induced by PGD2 and DHT via suppression of the Wnt/β-catenin pathway, with implications for potential therapeutic targets.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

PGD2 stops hair growth and is higher in bald men with AGA.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

This review discusses the role of Prostaglandin D2 and its synthase in androgenetic alopecia but reports no new clinical findings, suggesting pathways for future therapeutic development.

This article reviews mechanisms by which herbal ingredients may stimulate or inhibit hair growth, and it reports no new clinical findings while suggesting potential for developing hair loss treatments.

This review explored the new and emerging treatments for androgenetic alopecia and alopecia areata, finding that JAK inhibitors show promise for alopecia areata, while advancements in stem-cell research may eventually lead to new and improved treatments for androgenetic alopecia.

This review discusses advances in molecular biology and genetics related to androgenetic alopecia and reports no new clinical results.

This review discusses the potential roles of prostaglandin D2 and its receptor CRTH2 in various diseases beyond allergies and asthma and reports no new clinical results.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study examined the structural and biochemical mechanisms of human lipocalin prostaglandin D synthase, detailing substrate and product binding processes at the catalytic site and suggesting potential for drug delivery targeting hydrophobic molecules.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This review examines how different prostanoids and their receptors affect hair growth but provides no new clinical results; it highlights potential implications for treating hair disorders.

This study found that the n-hexane fraction from Leea indica leaves significantly increased hair growth in mice and showed potential as a natural treatment for alopecia.

This study found that 15-dPGJ2 promotes apoptosis in human follicular keratinocytes, suggesting its potential role in developing hair loss prevention treatments through DP2 antagonism.

This study identified a thiazolidine dione derivative as a potential inhibitor of 15-PGDH that may enhance prostaglandin activity in hair follicles, suggesting its use to support hair regrowth treatments.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

This article discusses the hypothesis that mechanisms driving androgenic alopecia may reduce the risk and proliferation of prostate cancer by increasing prostaglandin D2 levels but presents no new clinical findings.

This study suggests that AKR1C3 expression may influence PGD2-related pathways in skin squamous cell carcinoma and potentially be involved in androgenetic alopecia, although further investigation is needed to clarify its role.

This study found that increased levels of PGD2 and prostacyclin and decreased levels of PGE2 and PGF2α were associated with baldness in androgenetic alopecia, suggesting potential targets for treatment.

This study suggests that thermal imaging may aid in diagnosing cellulitis, potentially improving patient care, although its applicability to certain cases requires further investigation.

This study found that filamin A plays a crucial role in fibroblasts' ability to sense and respond to mechanical stimuli, significantly affecting wound closure and fibroblast-mediated processes in mice.

Inhibiting PGD2 and using dermal papilla cells may improve skin and hair regeneration.

This study suggests that the expression of the DP2 receptor is higher in balding scalp cells and that its knockdown could inhibit the transition to the catagen phase in cultured human hair follicles, potentially counteracting hair growth inhibition associated with male pattern baldness.

This review discusses current treatment options for androgenetic alopecia, noting that most lack robust evidence for efficacy and safety, highlighting the need for more comprehensive studies.

In this study, PGD2 treatment in keratinocytes increased testosterone production via reactive oxygen species, suggesting a potential role for the NRF2 pathway in androgenic alopecia treatment strategies.

This study identified that blocking the PTGDR2 receptor in human hair follicles in vitro and in mice reversed the hair growth inhibition caused by PGD2, suggesting a potential approach for treating alopecia.
