Androgens may influence T cells, contributing to higher autoimmune liver disease risk in women.
research TLR9 Activation in Large Wound Induces Tissue Repair and Hair Follicle Regeneration via γδT Cells
Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.
research Innate Immunity and the Regulation and Mobilization of Keratinocyte Stem Cells: Are the Old Players Playing a New Game?
Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.
research TGFβ and Cancer Metastasis: An Inflammation Link
TGFβ's manipulation of inflammation and immune cells affects cancer spread, suggesting new treatment strategies and biomarkers.
research Human αβ and γδ T Cells in Skin Immunity and Disease
Certain types of T cells are essential for healthy skin and play a role in skin diseases, but more research is needed to improve treatments.
research The Editor's Choice: Summary of Studies on Skin and Hair Conditions
UV radiation may cause DNA changes in skin, certain UVB therapy helps psoriasis, a new gene mutation is linked to mild piebaldism, different immune cells affect psoriasis, a drug promotes hair growth, and some cancer drugs could treat skin barrier issues.
research Stem Cells Tightly Regulate Dead Cell Clearance to Maintain Tissue Fitness
Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.
research Molecular Correlation With Clinical Outcomes in an Open Label Clinical Trial of Oral Tofacitinib in Patients With Alopecia Areata
Tofacitinib helped most patients with alopecia areata regrow hair and changes in immune cells were linked to the treatment's effectiveness.
research Stem Cells in the Body
Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.
research Local Heroes or Villains: Tissue-Resident Memory T Cells in Human Health and Disease
Tissue-resident memory T cells can protect against infections and cancer but may also contribute to autoimmune diseases.
research A Population of Radio-Resistant Macrophages in the Deep Myenteric Plexus Contributes to Postoperative Ileus Via Toll-Like Receptor 3 Signaling
Certain immune cells worsen post-surgery gut paralysis by activating a specific immune response.
research Emerging Interactions Between Skin Stem Cells and Their Niches
Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.
research A Subset of TREM2+ Dermal Macrophages Secretes Oncostatin M to Maintain Hair Follicle Stem Cell Quiescence and Inhibit Hair Growth
Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.
research Understanding Autoimmunity of Vitiligo and Alopecia Areata
Both vitiligo and alopecia areata involve an immune response triggered by stress and specific genes, with treatments targeting this pathway showing potential.
