In this study, frontal fibrosing alopecia showed a higher cumulative remission rate compared to lichen planopilaris, despite similar timeframes and relapse rates between the two conditions.

This study suggests that the expression and localization of toll-like receptors and caveolin-1 in lichen planopilaris may influence cicatricial alopecia pathobiology and that downregulating caveolae could offer a novel management strategy.

This study suggests that the expression of VLCFA biosynthesis genes is suppressed in skin hyperplasia and cancer, which could influence keratinocyte function.

This article reports on a typical case of lichen planopilaris with foreign-body granulomas around hair shaft material, suggesting these may be an additional criterion for diagnosing late-stage LPP/FFA.

This study found that mice lacking sPLA2-IIE had distinct skin abnormalities, particularly affecting hair follicles, highlighting the differing roles of sPLA2 isoforms in mouse skin.

This study suggests that although data on JAK inhibitors for treating LPP and FFA is mainly from retrospective studies and case reports, these inhibitors may offer a new treatment option, particularly for challenging cases.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study reported that the absence of Lsh in skin led to significant epidermal hyperplasia and altered gene expression, suggesting its crucial role in regulating epidermal proliferation, differentiation, and wound healing.

This article discusses Graham-Little Piccardi Lassueur Syndrome, a rare variant of Lichen planopilaris, but reports no clinical findings or results.

This study identified a specific LIPH gene mutation (736T>A) as common in Japanese patients with autosomal recessive woolly hair/hypotrichosis, potentially indicating its role in the condition's manifestation within this population.

This paper reviews treatments for lichen planopilaris, including low-level laser therapy, but reports no new clinical results and highlights the need for further research.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This study suggests that hairlessness in nude mice may be due to insufficient expression of phospholipase C-δ1, a molecule essential for normal hair development downstream of the Foxn1 gene.

This study found that platelet-rich plasma may be more effective and satisfactory than topical clobetasol for treating lichen planopilaris over six months.

This study observed that proteins in the mTOR signaling pathway are expressed differently in the hair follicles of patients with lichen planopilaris and frontal fibrosing alopecia, suggesting a role in the pathogenesis of these conditions.

A 70-year-old woman with a rare skin condition improved after treatment with topical steroids and acitretin.

This study found that canine pemphigus foliaceus skin lesions exhibit a distinct immune signature, with upregulated pro-inflammatory and Th17-related genes, showing similarities to human pemphigus. Further research using advanced sequencing is needed to better understand the disease's pathogenesis.

This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.

Fibrosing alopecia in a pattern distribution is a unique hair loss condition with inflammation and scarring, resembling but distinct from common balding.

The study suggests that immune privilege collapse in bulge cells and the involvement of pro-inflammatory cytokine interferon-γ contribute to hair follicle stem cell loss in lichen planopilaris.

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

This study found that three sessions of injectable platelet-rich fibrin (i-PRF+) significantly improved hair follicle density, hair volume, and thickness, as well as patient satisfaction in women with female pattern hair loss, with only minor self-limited adverse effects reported.

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 found that phosphorus and nitrogen deprivation increased root hair length in Brassica carinata and induced the expression of certain P-responsive genes, such as LRR and PRP.

This study found that PRMT5 inhibitors showed potent anti-tumor activity in models of adenoid cystic carcinoma and that combining these inhibitors with lenvatinib may have additional growth-inhibitory effects.

This review discusses partial longitudinal-follicular unit transplantation (PL-FUT) for hair loss and notes its potential to multiply hair follicles while preserving donor areas, but reports no new clinical results.

This study observed that disrupting the Pnkp gene in adult mice resulted in a premature aging-like phenotype, suggesting PNKP's vital role in maintaining normal growth and survival of certain progenitor cell populations.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

This research found that a biodegradable fibrous membrane incorporating fibroblast-derived ECM accelerated wound healing and improved neovascularization in a mouse model.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.
