Efficacy of Mesenchymal Stem Cells Therapy in Parasitic Infections: Are Anti-parasitic Drugs Combined with MSCs More Effective?

Purpose

Mesenchymal stem cells (MSCs) are mesodermal-origin postnatal stem cells that are able to self-renew and differentiate into several cell lineages. MSCs possess anti-inflammatory and anti-apoptotic activity, immunomodulatory action, as well as regenerative properties. Since MSCs also have antimicrobial properties, it has been suggested that they should be utilized for treating infectious diseases. In this study, the last pre-clinical advances in the efficacy of MSCs’ therapy against parasitic diseases were reviewed.

Methods

Data about the effects of MSCs’ therapy on experimental and pre-clinical parasitic infections were collected by searching relevant articles and reviewing them.

Results

In the present study, empirical findings on the impacts of MSCs’ therapy against parasitic diseases were recapitulated. Studies have reported that the administration of MSCs reduces the burden of the parasite and modulates the levels of inflammatory and anti-inflammatory cytokines in parasitic diseases, including schistosomiasis, malaria, cystic echinococcosis, toxocariasis, leishmaniasis, and trypanosomiasis. Also, the administration of MSCs combined with anti-parasitic drugs enhanced anti-parasitic effects and immunomodulatory actions.

Conclusion

Based on this review, empirical studies have revealed the beneficial effects of MSCs against some parasitic infections. This new therapeutic strategy showed both anti-parasitic and immunomodulatory effects. Also, the combination of anti-parasitic drugs with MSCs’ therapy promoted anti-parasitic and immunomodulatory activities against parasitic infections.
