    TLDR Tissue-resident memory T cells can protect against infections and cancer but may also contribute to autoimmune diseases.
    The document discussed the dual role of tissue-resident memory T (TRM) cells in human health and disease, highlighting their protective function against infections and cancer, as well as their harmful involvement in autoimmune skin diseases like psoriasis, alopecia areata, and vitiligo. It summarized the biology of TRM cells based on animal models and human studies, emphasizing the need for a deeper understanding of TRM cell mechanisms. This knowledge is crucial for developing safe therapeutic strategies that can boost protective immune responses without causing tissue damage and eliminate pathogenic TRM cells without compromising local immunity.

      community Verteporfin and Microneedling

      in Treatments 1 year ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
