A boy with severe immune deficiency and Epstein-Barr virus died from high-grade B-cell lymphoma.

A rare case showed hair regrowth after chemotherapy for thymoma, suggesting a link between alopecia areata and thymoma.

Using anthralin and calcipotriene together might help treat tough cases of alopecia areata, but more research is needed to understand how it works.

Women with scarring alopecia are less likely to have used hormone replacement therapy or oral contraceptives compared to those with female pattern hair loss.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Eating grape powder may reduce the severity of skin allergy symptoms.

Myoepithelial cells can repair airways after severe injury.

Zinc levels in body fluids can help diagnose zinc deficiency in lambs, with fecal zinc as an early indicator.

Both induced and spontaneous AA lymphocytes can cause alopecia areata in mice.

Polyomavirus A2 infection in newborn mice caused hair follicle tumors.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

The document concludes that understanding how the skin's immune system and inflammation work is complex and requires more research to improve treatments for skin diseases.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Cushing's syndrome can cause serious health problems, and early treatment is crucial, but some issues may remain after treatment.

The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

Hair follicle development and microbes help regulatory T cells gather in newborn skin.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

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

Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

Lupus affects the body and skin, causing joint pain and skin issues that can be treated with steroids and antimalarial drugs.

RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.

Transplant success has improved with better immunosuppressive drugs and donor matching.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

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