ABSTRACT

Background: Several epidemiologic studies in the United States and Europe have linked Alternaria sensitivity to both persistence and severity of asthma. In this study, we examined T cell responses and HLA class II alleles in children with moderate-severe asthma.

Methods: Ninety-six children with moderate-severe asthma were compared to 90 children with mild asthma. HLA class II genotyping was performed to determine HLA allelic frequencies. Th1/Th2 Alternaria-specific T cell cytokine responses were determined by the use of Alternaria-stimulated cultures. HLA class II restriction was examined by inhibition of Alternaria-stimulated lymphoproliferative responses with blocking anti-HLA class II monoclonal antibodies.
