October 2023 in “Journal of the Pakistan Medical Association” This source describes a case of a 12-year-old male diagnosed with folliculotropic mycosis fungoides, presenting with an asymptomatic, erythematous plaque. Histology and immunohistochemistry confirmed FMF, which is typically rare in children and marked by follicular infiltration by CD4+ lymphocytes.
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 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.
34 citations
,
January 2005 in “Journal of the American Veterinary Medical Association” This study found that cyclosporine A treatment at 5 mg/kg/day may reduce inflammation and promote gland regeneration in dogs with sebaceous adenitis, though symptoms returned when treatment stopped.
1 citations
,
June 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.
24 citations
,
October 2022 in “Cell Regeneration” This study describes a new mouse model for vitiligo that mimics key clinical features such as skin depigmentation and CD8 + T cell infiltration, providing a useful tool for in-depth research and drug discovery.
June 2024 in “Research Square (Research Square)” This study demonstrated that in mice, the absence of Jagged-1 expression in skin-resident regulatory T cells significantly delays wound healing by reducing the accumulation of neutrophils, highlighting the role of Jagged-1 in coordinating immune cell recruitment during injury.
16 citations
,
April 2007 in “Journal of Medical Primatology” This study reports that a 14-year-old female rhesus monkey with alopecia universalis was found to have a T-cell-mediated autoimmune disease similar to human alopecia areata universalis.

,
October 2022 in “International Journal of Molecular Sciences” This study suggests that allogenic human mesenchymal stem cell treatments have potential therapeutic effects by inducing immune tolerance and anti-inflammatory effects in severe alopecia areata patients.
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.
16 citations
,
April 2024 in “Proceedings of the National Academy of Sciences” This study found that selectively targeting HDAC4 and HDAC7 in mice can reduce Th17 cell-mediated intestinal inflammation, suggesting a potential treatment approach for Th17-related inflammatory diseases like ulcerative colitis.

September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” 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.
September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” 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.
