Rosacea is a skin condition with unclear causes, classified into four subtypes.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Platelet-rich plasma can potentially promote hair growth by stimulating cell growth and increasing certain proteins.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Blocking JAK-STAT signaling can lead to hair growth.

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

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Targeting the IL-23/IL-17 pathway effectively treats several inflammatory skin diseases.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

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

EGF and KGF signalling prevent hair follicle formation and promote skin cell development in mice.

Hair shedding is an active process that could be targeted to treat hair loss.

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

YAP and TAZ proteins are necessary for the development of two types of skin cancer.

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

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

Blocking IL-12/IL-23p40 helped reverse severe hair loss in patients.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

A second domain of high sulfur KAP genes on chromosome 21q23 is crucial for hair structure.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

RANK-RANKL signaling is essential for hair growth and skin health.

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.

TGFβ's manipulation of inflammation and immune cells affects cancer spread, suggesting new treatment strategies and biomarkers.

Human hair contains diverse proteins, including keratins and histones, which could help assess hair health and aging.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

Psoriasis is linked to other autoimmune diseases and involves a specific inflammatory process.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.
