    cells communicate through molecular signals to coordinate functions

    Cell signaling, also known as cell communication or signal transduction, is the process by which cells detect and respond to external signals through a series of molecular events. These signals can come from other cells, the environment, or within the cell itself, and they often involve the activation of specific receptors and subsequent pathways that lead to a cellular response, such as growth, division, or apoptosis. This process is crucial for maintaining homeostasis and coordinating complex biological functions.

      in Research/Science  17 upvotes 1 week ago
      Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

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

      in Research/Science  738 upvotes 3 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.
