    Abstract:
    Currently, the treatment of Trichinella spiralis (T. spiralis) intracellular infection by oral administration of albendazole (ABZ) is hampered by its poor aqueous solubility and rapid metabolism. Herein, the nanoparticles with BSA and ABZ (ABZ-BSA Nps) were constructed by a desolvation technique in the study. The anti-parasite activity and pharmacokinetics of ABZ-BSA Nps were evaluated for T. spiralis muscle larvae during the encysted phase. The immune-responsive cytokines of ABZ-BSA Nps were quantitatively analyzed. The results showed that ABZ-BSA Nps could eliminate the muscle larvae by triggering the unbalance of Th1/Th2 immune-response in the infection mice. For ABZ-BSA Nps treatment group, the plasma concentration of ABZSO (ABZ active metabolite) was higher than ABZ and the muscle larvae were reduced by 70.2 %. In conclusion, the study had constructed a successful prospective protein nanoparticle delivery ABZ and evidenced the ABZ could be used for intracellular parasite therapy by triggering the anti-parasite immunity of hosts.
