ABSTRACT
This study analyzed the changes in macrophage phagocytosis after Echinococcus multilocularis protoscoleces(PSC)infection.The distribution of macrophages in hepatic alveolar echinococcosis patients was analyzed by immunohisto-chemistry.PD-1 blockade,PSCs and macrophages were co-cultured to analyze macrophage phagocytosis and the expression lev-els of CD47 and PD-1.Macrophages labeled by CD68 aggregated in close live tissue from the lession of alveolar echinococcosis patients.PSC infection resulted in lower intensity of Escherichia coli and higher expression of CD47 and PD-1 than observed in the control group(P<0.001).The intensity of Escherichia coli increasedin the PD-1 blockade group after PSC infection(q=40.63,P<0.05).PD-1 blockade restored macrophage phagocytosis after PSC infection.
