This study found that a lotion with 5% minoxidil significantly altered immune parameters and disrupted immunological balance in guinea pigs, suggesting a substantial impact on both cellular and humoral immunity.

This study observed that dandruff is linked to a weakened immunoprivilege in hair follicles, with reduced Langerhans cells and increased epidermal CD4+ and CD8+ T cell infiltration.

This study found that Imaging Mass Cytometry effectively visualizes multiple biomarkers in alopecia areata, enhancing analysis of immune cell and tissue interactions in hair pathology.

This report diagnosed a 68-year-old man with comedonal folliculotropic mycosis fungoides based on clinical and histopathological findings, and found pegylated interferon alpha-2a with isotretinoin beneficial in reducing skin lesions.

This study found that epidermal growth factor receptor inhibitors used in cancer treatment induce a distinct inflammatory response in hair follicles, marked by immune privilege collapse and upregulation of inflammatory pathways.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

Arg1+ macrophages may play a role in causing alopecia areata.

This study reported that GA 0.1% spray led to only slight improvement in treating anogenital warts among HIV-positive patients over twelve weeks.

This study observed that in Korean HIV patients, tinea infection, folliculitis, and seborrheic dermatitis were the most common skin diseases, with HAART medications generally reducing folliculitis incidence. Skin disease prevalence differed by immune status, affecting treatment needs.

This study observed that, contrary to common belief, aged Balb/C mice showed better wound healing than younger mice despite greater weight loss, possibly due to increased T regulatory cells.

This article presents a diagnostic quiz based on clinical images and reports findings from the mentioned article but does not provide new clinical results.

This study found that hyaluronic acid increased the size and cell proliferation of mixed aggregates in a 3D culture model, indicating its role in human hair follicle germ-like structure formation without enhancing dermal papilla cell markers.

This study found that orally administering the CCR5 inhibitor Maraviroc improved hair loss in 4 out of 5 mice with alopecia areata and also reduced the development of the condition, evidenced by decreased CCR5+ T-cell infiltration in treated mice.

This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.

This study found that miR-486 and miR-451 levels were reduced in alopecia areata-affected skin, and delivering their mimics to mice mitigated symptoms by reducing inflammation and immune activity.

This study identified intramembrane proteolysis as a key feature of Astrotactin2 maturation, providing insights into its role in planar cell polarity hair patterning.

This study reported improvement in hair loss lesions in C3H/HeJ mice with alopecia areata following treatment with the CCR5 inhibitor maraviroc, alongside reduced infiltration of specific T cells in the lesions.

This study demonstrated that in vitro pig ear models effectively predict human follicular uptake of nanoparticles for potential transfollicular vaccination, but massage did not enhance nanoparticle penetration.

This study identified keratins as autoantigens in alopecia areata and found that a tolerogenic form of keratin application delayed disease progression in mice by affecting T-cell responses.

This summary reports that γδ T cells play a role in regulating hair follicle formation during wound healing in adult skin.

The authors developed a severe mouse model of chronic graft-versus-host disease and reported that rapamycin treatment improved survival compared to placebo, potentially by promoting regulatory T cell expansion.

This study established a murine chronic graft-versus-host disease model with scleroderma features, showing typical skin changes and cellular infiltrates associated with the condition.

This study suggests that contact sensitizers may treat alopecia areata by expanding suppressor cells and interfering with antigen presentation to lymphocytes.

This study demonstrated that transcutaneous vaccination via cyanoacrylate skin surface stripping effectively induced both CD4 and CD8 T cell responses in humans, offering a promising alternative to intramuscular injection.

Recent dermatological research highlights include new virus discoveries, genetic links to skin conditions, and insights into skin healing and pigmentation.

This review discusses the immune-mediated mechanism behind alopecia areata, highlighting similarities between the condition in humans and animals, and reports no new clinical results.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

People with acne have more CD4+ immune cells in their skin than healthy people.
