Background Alopecia areata (AA) is believed to have an autoimmune mechanism in which
the hair follicles are targeted by CD4+ and CD8+ lymphocytes. Studies investigating the …

Alopecia areata (AA) is a hair loss disorder resulting from an autoimmune reaction against
hair follicles. T-helper 1 cells are a major contributor to this disorder, but little is known about …

Alopecia areata (AA) presents as patches of hair loss, and progresses to include the entire
scalp (alopecia totalis; AT) or all body regions (alopecia universaris; AU) in 7% of affected …

Alopecia areata (AA) is generally regarded as an organ-specific autoimmune disease.
Although it has been hypothesized that the autoimmunity is mediated by T cells and that hair …

Cytotoxic T lymphocyte has been a concern for the etiopathogenesis of alopecia areata
(AA), some recent evidence suggests that the regulatory T (Treg) cell deficiency is also a …

Serum thymus and activation‐regulated chemokine/CCL 17 (s TARC) is known as a good
indicator for atopic dermatitis severity. Herein, we investigate whether s TARC correlates …

Alopecia areata (AA) is a putative, cell-mediated autoimmune disease of anagen stage hair
follicles. Inter-and intra-follicular lymphocytic infiltrates are associated with alopecia that may …

Importance An impaired inhibitory function of circulating CD4+ CD25+ regulatory T (Treg)
cells was reported to play a key role in alopecia areata (AA). We report the first use to our …

There is mounting evidence that T helper (Th) 17 cells and regulatory T cells (Treg) play
parts in the pathogenesis of autoimmune disease. Hence, levels of these T‐cell subsets in …

Background Alopecia areata (AA) is an organ‐specific autoimmune disease with T‐cell‐
mediated attack of hair follicle autoantigens. As T helper 17 (Th17) cells and T regulatory …
