This case report describes a 12-year-old boy with severe skin scaling due to novel compound heterozygous null truncation mutations in the TGM1 gene, resulting in loss of transglutaminase 1 activity.

This study found a significant positive correlation between hair thickness and growth rate, with a notably slower growth rate observed in men with male pattern hair loss compared to healthy controls.

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 article discusses the potential of using human hair follicles as a model to study prolactin's regulation and activities but reports no new experimental findings; the authors suggest further research in this area.

In this study, a patient with recalcitrant lichen planopilaris and frontal fibrosing alopecia showed significant improvement after receiving four doses of the interleukin-23 monoclonal antibody tildrakizumab.

This study suggests that lipin-1 plays a crucial role in keratinocyte differentiation by modulating protein kinase C activity through diacylglycerol levels, with implications for skin biology.

In a mouse model study, researchers observed that the absence of MCPIP1 in myeloid cells decreased susceptibility to chemically induced skin papillomas but caused significant hair loss and skin pigmentation changes, suggesting a role for MCPIP1 in skin carcinogenesis and follicle integrity.

This review article discusses the aesthetic impacts of GLP-1 medications like Ozempic (semaglutide), including "Ozempic Face," skin sagging, and loss of lean mass, and explores potential recovery methods such as biostimulators, HIFU, endolaser, and PRP.

In this study, BP201, derived from porcine lung phospholipids, promoted hair growth in mice, especially when combined with minoxidil, and increased hair follicle numbers and dermal papilla cell proliferation.

In this review, platelet concentrates were found to show comparable efficacy to steroids and immunosuppressive drugs in treating oral lichen planus, with some studies reporting more benefits and others noting more severe adverse reactions with platelet treatments.

In this case report, PRP therapy led to almost complete clearance of hypopigmentation in a 28-year-old Caucasian female after laser hair removal, suggesting PRP could be a promising treatment option for various hypopigmentation conditions.

This case report describes a 68-year-old man who developed both alopecia areata and bullous pemphigoid after starting linagliptin for diabetes, suggesting a possible link with DPP-4 inhibitors.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This review synthesizes current research on PPAR-γ signaling in hair follicle biology and its potential role in treating hair growth disorders like scarring alopecia and hirsutism, but reports no new clinical results.

This study found that targeting both hormonal and immune pathways improved treatment outcomes in androgenetic alopecia patients with an under-recognized inflammatory component called PIILIF, which may contribute to treatment resistance.

This study found that non-coherent intense pulsed light (IPL) treatment significantly reduced hair growth by about 80% in patients with skin type III-V without causing side effects.

This study found that the oral Janus kinase inhibitor CP-690,550 has a direct effect on reducing pruritus in patients with psoriasis, independent of clinician-assessed improvements in psoriasis severity.

This study found that intense pulsed light treatment achieved a mean of 85% hair reduction in two patients with faun tail, although local anesthesia may be needed due to severe pain associated with neurological abnormalities.

This study found that prolactin gene polymorphism in Changthangi goats showed no significant association with Cashmere quality traits, indicating the need for further research with larger sample sizes.

This study found that PGF2alpha analogues and PGE2 stimulated hair follicle activity in mice, with PGF2alpha analogues also linked to potential side effects like poliosis when used as eye treatments.

This article reviews the potential role of prolactin as a neuroendocrine modulator in skin biology and pathology, discussing its relevance for conditions such as psoriasis and hair growth, but reports no new clinical findings.

This study found that palmoplantar pustulosis patients exhibited oral dysbiosis, particularly among those with pustulotic arthro-osteosis, as compared to healthy controls.

This study found that in early retinal neurogenesis in mice, the transcription factor Lhx2 regulates Sonic Hedgehog signaling by controlling expression of pathway genes like the co-receptors Gas1 and Cdon.

This study identifies substance P, TNFα, and IFNγ as novel regulators of prolactin and its receptor expression in human skin, suggesting intracutaneous prolactin is not controlled by dopamine.

This study found that full thickness wounds in Lanyu pigs led to altered molecular expression and abnormal skin structure, without regenerating key epithelial cells thought to aid in skin regeneration.

This report describes a rare case of Graham-Little–Piccardi–Lassueur syndrome in a 46-year-old male, highlighting its typical features such as scarring alopecia and lichenoid follicular eruptions.

This study found that intravenous administration of a shark-derived receptor antibody, 3P17, promoted hair growth in mice by increasing hair matrix cell proliferation and activating leptin-STAT3 signaling, with transdermal leptin delivery enhancing this effect through improved skin penetration.

This study reported that the combination of a 308-nm excimer lamp and 10% liquor carbonis detergens significantly improved scalp psoriasis symptoms compared to the excimer lamp alone, with more patients achieving 75% reduction in their Psoriasis Scalp Severity Index.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.
