Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

MSC-derived exosomes can help treat COVID-19, hair loss, skin aging, and arthritis.

People with autoimmune skin diseases often have hearing problems and should get their hearing checked early.

BAY 43-9006 helps control kidney cancer growth but doesn't significantly increase overall survival.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

Androgens prevent hair growth by changing Wnt signals in cells.

PDGF signaling is crucial for maintaining and renewing hair follicle stem cells, which could help treat hair loss.

AIRE-deficient rats developed severe autoimmune disease similar to APECED, useful for testing treatments.

Finasteride helps reduce lung inflammation and damage after trauma and infection.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Understanding hair growth involves complex factors, and more research is needed to improve treatments for hair loss conditions.

The cause of alopecia areata is likely a mix of genetics, immune system issues, and environmental factors, with more research needed to understand it fully.

Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.

Cancer can hijack the body's cell repair system to promote tumor growth, and targeting this process may improve cancer treatments.

Lymphatic vessels help hair follicles regenerate by interacting with stem cells.

People with atopic dermatitis are more likely to develop other skin conditions due to shared genetics and immune pathways.

Immune cells around hair follicles help control hair growth and could be targets for treating hair disorders.

Vitamin D made by the skin plays a role in immune defense and skin health, and more research is needed to understand its full effects.

Mesenchymal stem cells could help treat aging-related diseases better than current methods.

Autoimmune diseases cause the immune system to attack the body, and management varies as some are curable and others are not.

Autoimmune diseases cause the immune system to attack the body, and management varies as some are curable and others are not.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

Alopecia areata is likely caused by a combination of genetic factors and immune system dysfunction, and may represent different diseases with various causes.

High lactate dehydrogenase activity is not necessary for the growth of squamous cell carcinoma.

Cytokines are important for immune responses and treating diseases, but they can cause side effects like fever and skin issues.

Alopecia areata is an autoimmune condition causing hair loss, linked to genetic factors and immune system issues, with no cure yet.
