    TLDR Activating TLR3 improves the healing and immune properties of periodontal ligament stem cells.
    The study conducted on December 10, 2016, explored the impact of Toll-like receptor 3 (TLR3) on periodontal ligament stem cells (PDLSCs). The researchers discovered that TLR3 stimulation significantly increased the expression of pluripotent stem cell genes (REX-1 and SOX2) and immunomodulatory molecules (IFNγ and IDO). The inhibition of NF-kB signaling influenced the TLR3-activated IFNγ and IDO expression, suggesting multiple pathways in the inductive mechanism. The study concluded that TLR3 activation could enhance the stem cell and immunosuppressive properties of PDLSCs, potentially aiding tissue healing and regeneration. Therefore, TLR3 activation in PDL cells could lead to effective periodontal ligament tissue regeneration.

      Hair loss treatments, specifically the use of finasteride, microneedling and potentially oral minoxidil. People discussed their experiences with finasteride, its effects on sexual behaviors, as well as potential solutions such as tadalafil or using other growth factor signal peptides for hope in curing male pattern baldness.

      The conversation humorously discusses hair loss treatments, including Minoxidil, finasteride, RU58841, and topical 17 alpha estradiol, with some users joking about transitioning to female to avoid baldness. The overall tone is satirical, emphasizing self-acceptance and the lengths people might consider for hair restoration.

      A 29-year-old woman is experiencing gradual hair thinning since age 15, suspects Androgenic Alopecia, and has tried 5% minoxidil with little success. She has purchased various hair loss treatments including minoxidil, dutasteride, finasteride, and spironolactone, but is cautious about starting them due to potential interactions with her ADHD medication.
