Farudodstat may effectively treat alopecia areata without harming hair follicles.
research 229 Single cell transcriptomics identifies a potential role for Arg1+ macrophages in alopecia areata pathogenesis
Arg1+ macrophages may play a role in causing alopecia areata.
research 5 alpha-reductase-2 gene mutations in the Dominican Republic.
This study identified multiple mutations in the 5 alpha-reductase-2 gene among male pseudohermaphrodites in the Dominican Republic, suggesting they do not share a common ancestry.
research Evaluation of oxidative stress, 3-Nitrotyrosine, and HMGB-1 levels in patients with wet type Age-Related Macular Degeneration
This study found that Wet-type Age-Related Macular Degeneration patients had higher oxidative stress and HMGB-1 levels compared to healthy controls, suggesting a link to increased tissue inflammation and necrosis.
research Age-related downregulation of dihydrotestosterone-inactivating enzymes in human scalp sebaceous glands
This research reported that AKR1C enzyme expression, particularly AKR1C4, in scalp sebaceous glands decreases with age, suggesting potential age-related changes in androgen metabolism affecting hair follicle health. Additionally, sulforaphane treatment increased AKR1C expression in related cell types.
research Ectodysplasin-A2 induces dickkopf 1 expression in human balding dermal papilla cells overexpressing the ectodysplasin A2 receptor
This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.
research First case of V281+I172N/V281L CYP21A2 genotype associated with congenital adrenal hyperplasia form. A case report from South Italy
This study identified a new genotype, V281+I172N/V281L, linked to non-classical 21-hydroxylase deficiency, suggesting it should be considered in genetic panels for the condition.
research 1377 Exploring the factors to regulate sweating by transcriptome analysis for anhidrosis: Novel role of olfactory receptors on sweating via exposing to β-ionone
This study found that olfactory receptor genes are differentially expressed in sweat glands of AIGA patients, suggesting these receptors may play a role in regulating sweating activity.
