This study synthesized and verified the structures of Setipiprant's major and minor metabolites, confirming their regio- and enantioselectivity from earlier proposals in a clinical study.

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.

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

This study found that oral setipiprant was safe but did not improve scalp hair growth compared to placebo in men with androgenetic alopecia.

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.

This study found that inhibiting JAK signaling can unexpectedly trigger hair growth in resting-phase mouse skin, implicating JAK-STAT pathways and oncostatin M in maintaining hair follicle stem cell quiescence.

This review discusses the role of LPA(3) in embryo implantation and its genetic connection with prostaglandin signaling, but reports no new clinical results.

In this review, researchers explored key mechanisms underlying androgenetic alopecia, revealing how hormonal, oxidative, inflammatory, and lipid dysregulation suppress hair growth pathways and suggesting new therapeutic targets such as DP2 antagonists and microbiome modulators.

This report discusses the Ninth World Congress for Hair Research and highlights the potential of hair follicle studies to advance understanding of various diseases, with no new clinical results presented.

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 suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

This review synthesizes knowledge on Prostaglandin E2's role in platelet biology and suggests that targeting PGE2 pathways could lead to personalized antiplatelet therapy without affecting hemostasis, but it presents no new results.

This study found that gypenosides from Gynostemma pentaphyllum increased procollagen synthesis in vitro and reduced periorbital wrinkles by about 14% in a clinical trial with 24 women.

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

This study suggests that setipiprant's inhibitory effect on aldose reductase may contribute to its anti-inflammatory properties, adding a possible mechanism beyond its known action on the prostaglandin D2 receptor.

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 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 study found that topical cetirizine treatment significantly improved hair regrowth and patient satisfaction in male patients with androgenetic alopecia compared to a placebo, highlighting its potential role in treatment.

This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.

This study found that compound 3, a tetrahydropyridoindole carboxymethylated at position 5, significantly inhibited sorbitol accumulation in both rat eye lenses and tissues affected by diabetes, indicating its potential as a lead compound for ALR2 inhibition.

This review reports that the treatment of androgenetic alopecia is shifting from single therapies to personalized, multimodal approaches incorporating both traditional and emerging pharmacologics, regenerative strategies, nutraceuticals, cosmeceuticals, and device-based interventions, with combination regimens showing improved outcomes.

This review examines the role of innate lymphoid cells in allergic diseases and the influence of an allergic microenvironment on their plasticity, without reporting new clinical outcomes.

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.

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

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This review analyzes therapies used for androgenic alopecia, highlighting potential advances from stem cell technologies and regenerative medicine, and reports no new clinical results.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

New drug shows promise for better hair growth in baldness treatment.

This review integrates studies on mouse models and human clinical observations to highlight the role of immune cells in skin development and how their dysregulation leads to skin disorders, suggesting potential therapeutic pathways for skin regeneration.
