Dynamic expression of CD30 on peripheral blood lymphocytes in mice after a cecal ligation and puncture

AIM: To investigate the details of Th2 cell differentiation in septic mice. METHODS: Experimental septic mice were induced by cecal ligation and puncture (CLP). The exression of CD30 on CD4⁺T cells at different time after CLP were estimated by flow cytometry following three-color immunofluorescent staining.RESULTS: CD30 expression on CD4⁺T cell was different at each time point. The highest expression was showed at 38 h after CLP and declined later, which matched the changes in mortality of the animals. CONCLUSION: During sepsis, differentiation of Th2 cell changed with the development of sepsis and might be associated with the severity of the disease.
