Sex hormones affect brain injury differently in males and females.

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.

Baricitinib helps treat several diseases, including COVID-19, but has side effects and needs careful monitoring.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Recombinant goat VEGF164 speeds up hair growth in mice.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Wnt signaling is crucial for skin development and health, and its disruption can cause skin diseases.

Estrogen therapy can reduce skin aging but has cancer risks.

BMP2 and BMP7 have opposite roles in feather formation.

Changes to the Foxp3 protein affect how well regulatory T cells can control the immune system, which could help treat immune diseases and cancer.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Both vitiligo and alopecia areata involve an immune response triggered by stress and specific genes, with treatments targeting this pathway showing potential.

The protein folliculin, involved in a rare disease, works with another protein to control how cells stick together and their organization, and changes in this interaction can lead to disease symptoms.
