Autophagy in human peripheral blood T lymphocyte / 中国免疫学杂志

ABSTRACT

Objective:To observe autophagy in human peripheral blood T lymphocyte.Methods:Peripheral blood T lymphocytes of healthy adults were separated with Percoll(1.073 g/ml) and harvested by using nylon column. The cultured cells were divided into control and dexamethasone(DXM) group, and cell morphology was observed through light microscope, electron microscope and fluorescent microscope at 0 and 72 h. And incidence rate of autophagy was analyzed by flow cytometry.Results:①The natural cultured T lymphocytes showed typical morphology of autophagy. ②There was significant statistic difference between 0 and 72 h incidence rate of autophagic T lymphocyte in both control and DXM group. ③There was significant statistic difference in 72 h incidence rate of autophagic T lymphocyte between control and DXM group.Conclusion:Autophagy can be seen in human peripheral blood T lymphocytes, and DXM could induce autophagy.
