    TLDR NSC167409 can effectively inhibit the virus causing hand, foot, and mouth disease.
    The study utilized human induced pluripotent stem cell-derived skin organoids (hiPSC-SOs) to investigate Enterovirus 71 (EV-A71) infection, a major cause of hand, foot, and mouth disease (HFMD) in children. It identified fibroblasts and epidermal cells as primary targets, with autophagy and abnormal proliferation of epidermal progenitor cells being key mechanisms. The FDA-approved inhibitor NSC167409 was found to effectively inhibit EV-A71 replication by suppressing virus-induced autophagy and inflammation, suggesting its potential as a therapeutic agent. The study also linked EV-A71 infection to skin aging and tumorigenesis and identified hair follicle stem cells as target cells, indicating a potential impact on hair growth. The research highlights the utility of skin organoid models in antiviral drug development, despite limitations such as the absence of blood vessels and immune cells.

      community Please explain this Minoxidil phenomena

      in Minoxidil  58 upvotes 1 year ago
      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  140 upvotes 1 year ago
      The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

      in Research/Science  738 upvotes 2 years ago
      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
