Outline of Final Research Achievements |
Although Th1 and Th2 cells are known to be involved in allergic inflammatory diseases, the molecular mechanisms underlying their differentiation are incompletely understood. Here, we identified CD155 as a costimulatory molecule on CD4+ T cells. CD155-mediated signaling induced Th1 development. Mice treated with anti-CD155 antibody exhibited attenuated Th1-type contact hypersensitivity. Thus, CD155 plays an important regulatory role in helper T-cell differentiation and allergic diseases.
