Alopecia areata (AA), an autoimmune hair-loss disease due to follicular inflammatory cell infiltration, lacks an ideal cure. The Periplaneta Americana (PA) extract (PA-011), a traditional Chinese medicine with anti-inflammatory, antioxidant, tissue-repair-promoting, and immune-regulating properties, was studied for its AA-treating effects.
Guided by network pharmacology, AA model mice were treated with PA-011. Hair growth, skin tissue, inflammatory factors, and Wnt protein levels were examined. Transcriptomics, metabolomics, and 16S rRNA sequencing explored the hair-growth-promoting mechanisms.
Network pharmacology showed PA-011 could regulate AA-related targets and pathways. PA-011 intervention promoted hair follicle cell proliferation and hair growth in AA mice, reduced skin TNF-α, IL-23, and VCAM-1 expression. Transcriptomics and WB analysis indicated PA-011 downregulated inflammatory genes, activated Wnt3a, and modulated the TGF-β pathway. Metabolomics found PA-011 regulated metabolic pathways. 16S rRNA analysis showed it reversed AA-induced skin microbiota changes, inhibiting pathogens and promoting probiotics. Multi-omics analysis revealed PA-011 regulated skin microbiota and metabolic balance for hair growth.
In conclusion, PA-011 alleviates AA by reducing skin inflammation and modulating skin microbiota, suggesting its potential as an AA therapeutic.
斑秃(AA)是一种由于毛囊炎性细胞浸润导致的自身免疫性脱发疾病,目前缺乏理想的治疗方法。美洲大蠊提取物(PA-011)是一种具有抗炎、抗氧化、促进组织修复和免疫调节特性的传统中药,本研究对其治疗斑秃的效果进行了探究。
在网络药理学的指导下,用PA-011对斑秃模型小鼠进行治疗。检测毛发生长、皮肤组织、炎性因子和Wnt蛋白水平。通过转录组学、代谢组学和16S rRNA测序探索促进毛发生长的机制。
网络药理学显示PA-011可调节与斑秃相关的靶点和通路。PA-011干预可促进斑秃小鼠毛囊细胞增殖和毛发生长,降低皮肤肿瘤坏死因子-α(TNF-α)、白细胞介素-23(IL-23)和血管细胞黏附分子-1(VCAM-1)的表达。转录组学和蛋白质免疫印迹分析表明,PA-011可下调炎性基因,激活Wnt3a,并调节转化生长因子-β(TGF-β)通路。代谢组学发现PA-011可调节代谢通路。16S rRNA分析显示,它可逆转斑秃引起的皮肤微生物群变化,抑制病原体并促进益生菌生长。多组学分析表明,PA-011通过调节皮肤微生物群和代谢平衡来促进毛发生长。
总之,PA-011通过减轻皮肤炎症和调节皮肤微生物群来缓解斑秃,表明其作为斑秃治疗药物的潜力。
