January 2019 in “Dermatology Online Journal” In this case report, a 62-year-old woman's persistent frontal fibrosing alopecia while on the psoriasis medication ustekinumab suggests that IL-12 and IL-23 inhibition may not be effective in treating this scarring alopecia, challenging the role of Th1 and Th17 pathways in its pathogenesis.
4 citations
,
January 2011 in “Journal of UOEH” In this case study, the progression of alopecia universalis in a Japanese man was linked to the involvement of Th1 and Th17 cells, suggesting an autoimmune mechanism.

,
January 2016 in “Journal of Clinical & Cellular Immunology” In this study, increased production of CXCL10 was associated with the infiltration of Th1 and Tc1 cells in acute alopecia areata, suggesting a possible new target for treatment.
2 citations
,
April 2018 in “Journal of Investigative Dermatology” This study suggests that frontal fibrosing alopecia is a highly inflammatory disease involving TH1 and JAK-STAT pathways, without reduced hair keratins, highlighting JAK-STAT signaling as a potential therapeutic target.
2 citations
,
May 2025 in “Journal of Clinical Medicine” This study reported that in a case series of three adolescents with alopecia areata and atopic dermatitis, treatment with 15 mg/day of upadacitinib led to rapid improvement in skin symptoms and significant hair regrowth over 12 months, with no severe adverse events observed.
1 citations
,
July 2025 in “Frontiers in Genetics” In this study, researchers classified melanomas by filaggrin expression levels and found that in filaggrinHigh melanomas, there are significant changes in FGFR signaling and impaired GNA14 and Th1 signatures, linked to genetic and immune alterations associated with pruritus.
1 citations
,
August 2023 in “Biomolecules” This study found that patients with alopecia areata and their healthy family members had elevated levels of Th1- and Th17-related cytokines, suggesting a genetic link in cytokine dysregulation.
1 citations
,
April 2023 in “World Journal of Urology” In this study, researchers found that using a 5-α reductase inhibitor may reduce inflammation-related cytokines associated with T-helper cell 1 and T-helper cell 2 in prostate tissues after surgery, but it did not affect those related to Th17 cells.
April 2019 in “Journal of Investigative Dermatology” Targeting immune pathways like JAK/STAT may help treat frontal fibrosing alopecia.
April 2018 in “Journal of Investigative Dermatology” This study found that both Th1 and Th2 cytokine markers were elevated in the serum and skin of patients with alopecia areata, with Th2 markers more closely linked to disease severity.
In this study, researchers found that CD4 T cells from the skin draining lymph nodes of mice with alopecia areata can transfer the disease to recipient mice, highlighting the key role of these cells and their interaction with CD8 T cells in the disease's development.
April 2023 in “Journal of Investigative Dermatology” In this study, researchers developed a mouse model of scarring alopecia and observed significant reductions in CD200R expression in affected skin, potentially linking this signaling pathway to immune attacks on hair follicles and suggesting new treatment targets for scarring hair loss.
