Detection of anti-IgE anti-FcεRI α chain auto-antibodies in patients with atopic dermatitis

Anti-IgE and anti-FcεRI α chain auto-antibodies have been detected in the sera of atopic and non-atopic subjects; however, the biological activity of these auto-antibodies is still unclear. These two kinds of autoantibodies were examined in atopic dermatitis (AD) patients. In results, 12 of 92 AD pa...

description Anti-IgE and anti-FcεRI α chain auto-antibodies have been detected in the sera of atopic and non-atopic subjects; however, the biological activity of these auto-antibodies is still unclear. These two kinds of autoantibodies were examined in atopic dermatitis (AD) patients. In results, 12 of 92 AD patients have the anti-IgE, eight have the anti-FcεRI α auto-antibodies and two have both auto-antibodies. Furthermore, biological characterization of these auto-antibodies has been performed. In results, three of 12 samples with the anti-IgE auto-antibodies exhibited inhibitory activity for IgE-FcεRI α binding. Two of the eight samples with the anti-FcεRI α auto-antibodies and one of the two samples with both auto-antibodies had histamine releasing activity. It is documented here that both anti-IgE and anti-FcεRI α auto-antibodies were detected in some AD patients, some anti-IgE auto-antibodies had inhibitory activity for IgE-FcεRI binding and also histamine releasing activity was detected in the anti-FcεRI α chain auto-antibody.
