Men are more likely to have severe respiratory viral infections like COVID-19 due to hormonal and genetic differences, while women generally have stronger immune responses.

Human prenatal skin develops an immune network early on that helps with skin formation and healing without scarring.

Alopecia Areata is an autoimmune condition causing hair loss, influenced by genetics, environment, and possibly improved by anti-MIF therapy, with many patients experiencing regrowth within a year.

The study suggests that hypothyroidism may cause alopecia areata.

Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.

Hair loss can be caused by stress, infections, drugs, and various diseases, with treatment depending on accurate diagnosis.

Certain microRNAs are linked to various skin diseases and could be used to diagnose and treat these conditions.

Certain drugs increase calcium levels in cancer cells by triggering internal calcium release.

Genetic mutation and carcinogen treatment are both needed for skin cancer to develop in these specific mice.

Imiquimod cream activates hair follicle stem cells and causes early hair growth by changing immune cells and certain protein expressions.

The JAK/STAT pathway is important in cell processes and disease, and JAK inhibitors are promising for treating related conditions.

Lichen planus is a chronic autoimmune disease that is hard to treat and more common in women.

The document concludes that early diagnosis and a comprehensive treatment plan are crucial for managing hair loss in children, with a focus on both medical and psychological support.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Wnt activation shows promise for regenerative medicine but requires selective targeting to minimize risks like cancer.

Different types of skin cells play specific roles in development, healing, and cancer.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

New patents show progress in developing drugs targeting the Wnt pathway for diseases like cancer and hair loss.

Damaged hair follicles make mice more prone to skin inflammation and skin cancer after UV exposure.

Single-cell engineered biotherapeutics show promise for skin treatment but need more research and trials.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

TAF4 is important for skin cell growth and helps prevent skin cancer in mice.

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.

Skin healing from blisters can delay hair growth as stem cells focus on repairing skin over developing hair.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

The secretome from mesenchymal stem cells is a promising treatment that may repair tissue and avoid side effects of stem cell transplantation.

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

Distinct β-catenin patterns are linked to cell growth, not cell death, in lung cancer.
