| Research Abstract |
To study the role of CD4/CD8 T cell in the pathogenesis of pulmonary hypertension (PH), the severity of lung inflammation and right ventricular hypertrophy(RVH) was evaluated in monocrotaline(MCT)-induced CD4- or CD8- deficient mice as well as wild-type mice. The inflammation responses in lung were observed in all MCT-induced groups, however, RVH were only observed in wild -type mice, not CD4- nor CD8- deficient mice. From all these results, CD4 and CD8 T cell groups might be associated with the development of pulmonary hypertension.
