The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

MendelVar is a tool that helps identify important genes by combining GWAS data with Mendelian disease information.

The Asiatic lion has very low genetic diversity and unique genetic traits, highlighting the need for its conservation.

TLR2 is important for hair growth and can be targeted to treat hair loss.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

Hair follicle stem cells help skin heal and grow during stretching.

Sweat gland development involves two unique skin cell programs and a temporary skin environment.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

The Rotterdam Study updated findings on elderly health, focusing on heart disease, genetics, lifestyle effects, and disease understanding.

Increasing mir-302 turns human hair cells into stem cells by changing gene regulation and demethylation.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

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

Researchers created human hair follicles using a new method that could help treat hair loss.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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

Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Fat cells in the skin help start healing and form important repair cells after injury.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

White lupin uses specific genes to grow root hairs and access phosphorus when it's scarce.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.
