This study found that diphenylcyclopropenone (DPCP) was more effective and better tolerated than dinitrochlorobenzene (DNCB) in promoting hair regrowth in patients with alopecia areata.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This study found that Pdgfα signaling is crucial for maintaining dermal adipose tissue in mice by initiating dermal adipocyte stem cell proliferation, with implications for age-related skin defects.

This review analyzes PDRN's molecular mechanisms and therapeutic applications in anti-aging dermatology but reports no new clinical results, highlighting the need for more standardized protocols and long-term evaluations.

This study observed that erosive pustular dermatosis of the scalp in elderly patients was effectively treated with high-potency topical steroids, with plasma and lymphocyte dermal infiltrates helping to confirm diagnosis.

This study found that combining a thulium laser with intra-perifollicular PDRN injections significantly improved hair thickness but not hair counts compared to mesotherapy and PDRN in patients with pattern hair loss.

This study observed that autologous PRP and PDRN injections improved hair thickness and density in women with pattern hair loss, with combined therapy showing greater improvement in thickness than PDRN alone.

This study observed that while topical drug therapy for erosive pustular dermatosis rarely leads to complete resolution, surgery may achieve remission in male patients.

This study found that Diphenylcyclopropenone (DCP) was effective for treating extensive alopecia areata in Thai patients, although a high relapse rate suggests maintenance therapy might be necessary.

This study found that PLDζ2 and NPC4 enzymes play distinct roles in lipid remodeling and root hair growth in Arabidopsis under phosphate deficiency, influencing root hair density and length in a tissue- and time-specific manner.

This study found that dexamethasone treatment inhibited the inflammatory response and the induction of ornithine decarboxylase activity in mouse skin after TPA application, although the effect on ODC was weaker during the hyperplastic stage.

This review discusses the formation and goals of the Pediatric Dermatology Research Alliance (PeDRA) but reports no new clinical results; it emphasizes collaborative research to advance treatment options for pediatric skin disorders.

Avoiding dyed wigs and clothing improved severe allergic reactions in a woman treated with diphencyprone.

This review discusses the various roles of skin-resident dermal white adipose tissue in hair growth inhibition, antibacterial responses, and wound healing, reporting no new empirical findings.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

This article reviews the definitions, opportunities, advantages, and limitations of dental pulp stem cells and stem cells from human exfoliated deciduous teeth in tissue engineering and regenerative medicine, reporting no new clinical results.

This study suggests that central centrifugal cicatricial alopecia may involve a CD4-predominant T-cell process with potential PD1/PDL1 pathway involvement, indicated by increased caspase 3 expression and loss of PDL1.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This study found that diphenylcyclopropenone therapy resulted in over 50% hair regrowth in 71% of alopecia totalis patients, with a significant relapse association with thyroid disease, suggesting treatment could be viable but should continue for at least two years.

This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

This study found that maintenance treatment with diphenylcyclopropenone was associated with a lower relapse rate in alopecia areata patients, highlighting the importance of adjusting treatment intervals post-improvement.

This study found that the 15-PGDH inhibitor DPP improved endothelial function in hair-related cells exposed to DHT by reducing oxidative stress and enhancing angiogenic capacity.

This case report suggests that topical diphenylcyclopropenone (DPCP) may be beneficial for treating both alopecia areata and verruca vulgaris, although it is not typically a first-line therapy.

This study found that topical DPCP was more effective for hair regrowth in resistant alopecia areata compared to anthralin, with both treatments having similar safety profiles.

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

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

This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

This study reviewed existing articles to assess the efficacy of topical diphenylcyclopropenone immunotherapy for alopecia areata, but it did not report new clinical results.

In this study, fibroblasts treated with the small molecule peficitinib were reprogrammed into dermal papilla cell-like cells capable of inducing hair growth, offering a new strategy for hair loss treatment.
