title: [Anti-tuberculous IgE antibodies. I. Immunodominant antigens].
abstract: It is widely accepted that protection against tuberculosis is provided by the formation of type 1 immune response, which is characterized by the production of IFN-gamma and IL-2. However, type 2 antimycobacterial immune response is also present: specific IgE antibodies that are IL-4 dependent, are usually found in tuberculosis patients. There is elevated production of type 2 cytokines in some cases. Thus, both types of an immune response can simultaneously develop, probably counteracting with each other. It is unknown which of mycobacterial antigens are capable of inducing a preferential type 2 response. To detect these antigens, the authors studied tuberculosis IgE antibodies in the sera of 500 tuberculosis patients by using the ELISA assay with ultrasonic disintegrated M. Tuberculosis H37Rv (sonicate). Antigens recognized by IgE antibodies were found to be localized in the cell wall of mycobacteria. The IgE-response was specific since the sera did not react with the antigens of atypical mycobacteria and other bacterial species.
