Abstract

The IgE response to Cryptomeria japonica pollen antigen (CPAg) in vivo was determined by radioimmunoassay of the plasma of 525 members from 98 families with known nasal allergies. Based on responses, patients were classified into a non-responder or low-responder group (non/low) and a high-responder group. Segregation analysis revealed that the IgE non/low responsiveness to CPAg involved a single dominant trait. The gene frequency was calculated to be 0.44-0.60. The IgE non/low response to CPAg was found to be mediated by CPAg-specific suppressor T cells. These findings demonstrated that the phenotypic variation of IgE responsiveness to CPAg is not due the immune response gene, but rather is mediated by the immune suppression gene for CPAg, via CPAg-specific suppressor T cells.
