Glossary Immune Privilege Collapse

breakdown of immune protection in areas like hair follicles

Immune Privilege Collapse refers to the breakdown of a body's natural protection in certain areas, like the eyes or hair follicles, where the immune system usually doesn't attack. When this collapse happens, the immune system mistakenly targets these areas, leading to conditions like alopecia, where hair falls out because the immune system attacks hair follicles.

research 051 γδ T cells as novel players in alopecia areata pathobiology: Vδ1 + T lymphocytes may recognize “stressed” hair follicle keratinocytes, leading to IFNγ-dependent hair follicle dystrophy and immune privilege collapse

1 citations , April 2016 in “Journal of Investigative Dermatology”

This study suggests that NKG2D+ Vδ1 T cells may contribute to hair follicle pathology in alopecia areata by recognizing stressed keratinocytes and inducing immune privilege collapse.

research ISIDLB1777 - A novel ex vivo model of human hair follicle immune privilege collapse reveals the potential of farudodstat, a DHODH inhibitor, as a therapeutic for alopecia areata treatment

May 2023

This study found that in an ex vivo model simulating alopecia areata, the DHODH inhibitor farudodstat reduced T-cell proliferation and MHC protein expression in hair follicles, suggesting it may protect against immune privilege collapse without cytotoxic effects.

community My Theory Of Androgenic Alopecia

16 upvotes 10 months 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 PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 2 years ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
