GlossaryMacrophage Polarization

process where immune cells change roles based on signals

Macrophage polarization refers to the process by which macrophages, a type of immune cell, change their functional state in response to different signals in their environment. They can adopt a pro-inflammatory state (M1) to fight infections or a healing state (M2) to repair tissues. This ability to switch roles is crucial for maintaining balance in the immune system and is important in conditions like infections, cancer, and autoimmune diseases.

community The Worst Hair Loss Condition You (MAY) have: LPP

in Research/Science 43 upvotes 3 months ago

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 4 months 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.

community Verteporfin and Microneedling

in Treatments 6 months 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.
