- AB More than 500 CD4+ T-cell clones (TCCs) derived from the skin of eight
- patients with atopic dermatitis (AD), two patients with nonatopic
- dermatologic disorders, two patients with allergic rhinitis, and one
- healthy nonatopic donor were analyzed for both their pattern of cytokine
- production and their antigen specificity. The proportions of TCCs from
- patients with AD producing interleukin-4 in response to stimulation with
- phorbol 12-myristate 13-acetate plus anti-CD3 antibody were higher,
- whereas the proportions of interferon-gamma--producing TCCs were lower
- than those of control subjects. In two patients with AD, the majority of
- TCCs had a TH2/TH0-like phenotype, whereas in six patients with AD a
- TH1/TH0-like phenotype was prevalent. TCCs with a TH2/TH0-like phenotype
- were also isolated from the healthy skin of two patients with allergic
- rhinitis and one nonatopic donor. In contrast, no TH2-like TCCs were
- derived from the skin of the two patients with dermatologic disorders of
- nonallergic origin. No unambiguous correlations was found between the
- proportions of TCCs producing interleukin-4 or interferon-gamma (or of
- TCCs with TH2- or TH1-like profile) and the level of total serum IgE,
- suggesting that CD4+ T cells infiltrating the atopic skin do not play a
- major role in the production of serum IgE antibodies. When TCCs from
- five patients with AD were examined for their specificity, the
- proportions of allergen-specific (Dermatophagoides pteronyssinus and Lol
- p 1) clones were consistently 6% or lower even in patients with high
- titers of ryegrassor D. pteronyssinus-specific IgE antibodies. Because
- similar percentages of allergen-specific TCCs were found in skin from
- two healthy control subjects, the role of aeroallergens in favoring and
- maintaining skin lesions in patients with AD remains unclear.
