GlossaryParacrine Signaling

cells communicate by releasing molecules to nearby cells

Paracrine signaling is a form of cell-to-cell communication where a cell produces signaling molecules, such as growth factors or cytokines, that affect nearby target cells within the same tissue. Unlike endocrine signaling, which involves hormones traveling through the bloodstream to distant targets, paracrine signals act locally, ensuring a rapid and specific response in the immediate cellular environment. This type of signaling is crucial in processes like wound healing, immune responses, and hair follicle regulation.

To Control Site-Specific Skin Gene Expression, Autocrine Mimics Paracrine Canonical Wnt Signaling and Is Activated Ectopically in Skin Disease

research To Control Site-Specific Skin Gene Expression, Autocrine Mimics Paracrine Canonical Wnt Signaling and Is Activated Ectopically in Skin Disease

23 citations, May 2016 in “American Journal of Pathology”

research Androgen Receptor-Mediated Paracrine Signaling Induces Regression of Blood Vessels in the Dermal Papilla in Androgenetic Alopecia

6 citations, January 2022 in “Journal of Investigative Dermatology”

Male pattern baldness is linked to higher levels of a certain receptor in the scalp, which leads to the shrinking of blood vessels and hair loss. Early treatment targeting this receptor could be more effective.

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

in Research/Science 739 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.

community An argument for why we should take topical Dutasteride seriously

in Research/Science 85 upvotes 3 years ago

Topical Dutasteride may halt hair loss and effectively treat androgenic alopecia. Combining low-dose oral Dutasteride with topical application could maximize regrowth and minimize side effects.

community I started rapidly diffuse thinning at 22. I'm 42 now and have as much hair as I did at 16. AMA

in Treatment 449 upvotes 4 years ago

Hair loss treatments like finasteride, minoxidil, ketoconazole, PRP, and microneedling helped maintain hair for 20 years. Research and try evidence-based treatments for best results.

community hmi115 is coming. Prepare yourselves for what's coming

in Technology 110 upvotes 1 year ago

The conversation discusses HMI-115, a potential cure for hair loss. Users share mixed opinions, with some expressing skepticism and others sharing anecdotal evidence of its effectiveness, including photos of significant hair regrowth from a trial participant.

community Why HMI115 should work if it doesn’t affect dht?

in Research/Science 16 upvotes 1 year ago

Hair growth can be induced without stopping DHT, as seen with Minoxidil. HMI115 may work by promoting follicle growth, not targeting the root cause of hair loss (DHT).
