Objective To explore the inhibitory effect of dendritic cell(DC)subsets from mice infected with Schistoso majaponicumon allergic asthma and their mechanism of action. Methods CD8α+DC and CD8α-DC were extracted from spleens of mice infected with S.japonicumusing MACS(SJCD8α+DC and SJCD8α-DC)and were adoptively transferred to BALB/c mice(an SJCD8α+group and an SJCD8α-group).Then,allergic asthma was induced with OVA.Normal mice(the Normal group)and untreated mice with induced asthma(Asthma group)served as cont...
