Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

The study concluded that immune cells attacking hair follicles cause hair loss in alopecia, with genetics and environment also playing a role, and highlighted the potential of certain treatments.

A specific protein in chicken embryos links early skin layers to feather development.

George Ernest Rogers was a notable scientist who made important discoveries about hair and wool proteins.

M2 macrophages help hair regrowth in wounds by making growth factors.

Scientists discovered a unique hair protein, KAP24.1, with a special structure, found only in the upper part of hair cuticles.

Molecular diagnostics help identify genetic defects causing endocrine diseases, improving diagnosis and treatment options.

Tandem repeats significantly influence hair color, especially darker shades, across different ancestries.

Mongolian gerbils heal wounds differently than mice, with unique protein levels and gene expression that affect skin repair.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

Gene differences found in hair follicles linked to male baldness.

Colorectal cancer development involves both genetic changes and epigenetic alterations like DNA methylation and microRNA changes.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

The human type II 5α-reductase gene has a specific structure important for understanding certain medical conditions.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

Fingerprints form uniquely before birth due to specific genetic pathways and local signals.

Beta-HPV and MCPyV are linked to certain skin cancers, with ongoing research and vaccine development.

Mutations in the PADI3 gene are linked to a higher risk of scarring hair loss in women of African descent.

The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.

DHEA stimulates skin oil glands and could help postmenopausal women, with potential for acne and excessive hair growth treatments.

HNG may help prevent the negative effects of chemotherapy on sperm production and white blood cell counts.

Rare changes in the KRT82 gene are linked to a higher risk of Alopecia Areata.

P-cadherin is important for hair growth and health, and its problems can cause hair and skin disorders.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.
