research Psoriasis patients demonstrate HLA-Cw*06:02 allele dosage-dependent T cell proliferation when treated with hair follicle-derived keratin 17 protein
Psoriasis patients' immune response to a hair protein depends on their specific gene type.
research Idiopathic CD4+ T-lymphocytopenia
ICL is a condition with low CD4+ T cells like AIDS but not caused by HIV, and normal CD4+ T cell counts may vary between men and women.
research Diffuse alopecia areata is associated with intense inflammatory infiltration and CD8+ T cells in hair loss regions and an increase in serum IgE level
Diffuse alopecia areata involves more inflammation and higher allergy-related antibodies than patchy types.
research Low-Dose IL-2 for Treating Moderate to Severe Alopecia Areata: A 52-Week Multicenter Prospective Placebo-Controlled Study Assessing its Impact on T Regulatory Cell and NK Cell Populations
The study's results on the effectiveness of low-dose IL-2 for alopecia areata and its impact on immune cells were not provided.
