This study suggests that macrophages, particularly CD206⁺ macrophages, play a crucial role in squaric acid dibutylester-induced hair growth in alopecia areata treatment.

This study found that a single instance of acute skin stretching can enhance immune surveillance and improve vaccine delivery by increasing skin permeability and promoting immune cell recruitment without causing tissue damage.

This study conducted a scoping review and meta-analysis revealing a complex chemokine profile in alopecia areata patients, with elevated Th1, Th2, and other immune pathway chemokines, suggesting broader immunomodulatory strategies may help address the disease's multifaceted immune dysregulation.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata show a complex serum chemokine profile, predominantly involving Th1- and Th2-associated chemokines, suggesting that broader immunomodulatory strategies might address the diverse immune dysregulation observed in the disease.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata exhibit complex chemokine profiles, with elevated levels of Th1, Th2, and other immune pathway-associated chemokines, suggesting the potential for broad immunomodulatory strategies to address the disease's immune dysregulation.

Ritlecitinib may help treat alopecia areata by protecting hair follicles.

Immune system changes may contribute to female pattern hair loss.

This study found that patients with alopecia areata, particularly those with severe cases, exhibit significant systemic immune dysregulation, including altered cell communication networks and epigenetic remodeling in immune cells, suggesting potential pathways for therapeutic targeting.

This review indicates that mesenchymal stem cell therapy may offer clinical improvements for immune-mediated inflammatory skin diseases, showing promise particularly for those unresponsive to traditional treatments, but emphasizes the need for larger, controlled trials to confirm these results.

This study reviewed therapies for alopecia areata and suggests that Janus kinase inhibitors, such as baricitinib and upadacitinib, show promise in treating both alopecia areata and associated immune-mediated inflammatory diseases.

In this case study, a nine-year-old boy with alopecia universalis following severe chickenpox showed complete hair regrowth after treatment with tofacitinib, suggesting the drug's potential in managing varicella-zoster virus-induced alopecia by modulating immune responses.

This study found that immune privilege is preserved in hair follicles of nonsegmental vitiligo patients compared to those with alopecia areata, potentially protecting follicular melanocytes from autoimmune attacks.

In this report, oral baricitinib improved both alopecia areata and immune thrombocytopenia in a 56-year-old patient, suggesting a potential dual benefit for these conditions, although regular platelet monitoring and hematology consultation are recommended.

In this study, a nanoparticle system codelivering diphenylcyclopropenone and rapamycin successfully induced immune tolerance and promoted hair regrowth in a mouse model of alopecia areata, offering a promising new therapeutic strategy for this autoimmune condition.

In this study, plasmatherapy was found to improve immune status indicators in patients with vitiligo, particularly benefiting those with segmental vitiligo by normalizing immune markers and reducing IL-6 levels, suggesting its potential as an adjunct treatment to slow depigmentation progression.

This review highlights the potential of combining immune regulation, phototherapy, and dietary strategies for effective vitiligo treatment, but emphasizes that more research is needed.

Alopecia areata is linked to immune system differences, with specific biomarkers like CXCL9 and CXCL10 being key for diagnosis and potential treatment targets.

The study investigated immune cell patterns around the hair follicle infundibulum in androgenetic alopecia, revealing significant differences in immune signatures between patients with AGA and control donors, specifically noting an enrichment of CD4 cells in the patient group.

Hemp seed biomaterials may reduce hair loss and improve hair growth.

Certain immune cells are linked to non-scarring hair loss, suggesting potential for immune-targeted treatments.

This study found that a dietary intervention in dogs alleviated atopic dermatitis symptoms by modulating immune responses and skin microbiome composition compared to baseline, but with similar non-significant trends when compared with a positive control diet.

This study found that germinated hemp seeds extract and exosomes from their calli can prevent androgenetic alopecia by modulating genetic, cellular, and immune responses in hair follicle dermal papilla stem cells and CD8+ T cells, with exosomes being more effective.

This study reports that chemotherapy-induced hair loss affects up to 65% of patients, typically within 1 to 3 weeks of treatment, while scalp cooling may help prevent severe hair loss with taxane-based therapies.

This review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.

This review highlights the diagnostic potential and therapeutic prospects of exosomes, discussing their use in managing chronic immune-mediated skin conditions, alopecia, and wound healing through their capacity to deliver regulatory molecules between cells.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

This study found that faster algorithms for inferring ancestry in genomic data can better capture historical and functional insights into genome variation than traditional methods in large datasets like the UK Biobank.

The researchers in this study identified molecular mechanisms involved in frontal fibrosis alopecia, highlighting immune response and fatty acid metabolism, and developed a four-gene diagnostic model showing high accuracy in distinguishing affected individuals from controls.

This study investigated how different 3D bioprinted scaffold structures affect immune responses and hair growth in mice, finding that moderate immune response induced by certain structures stimulates hair growth, while excessive immune response can hinder hair follicle development.
