“…These data were in agreement with the findings of Atallah et al [12] in mice. Focal area of hepatic lytic necrosis with mononuclear infiltrates and biliary hyperplasia was also observed in the untreated T. vitulorum-rat model that was parallel to the findings of Kumar et al [44] who attributed the changes to the immune response against T. vitulorum infection. Several investigators studied the migration of Toxocara larvae in mice [12,13].…”

Background and Aim: Toxocara vitulorum is a bovine intestinal nematode. Immune pictures following infection are conflicting and stopping anthelmintic albendazole treatment recording reversed liver abnormalities. The purpose of this work was to evaluate the therapeutic potential of bone marrow mesenchymal stem cells (BMMSCs) therapy, subsequent to albendazole administration in rats infected with T. vitulorum. Materials and Methods: The ultrasonographic and histopathological examinations as well as serum liver enzymes activity and the kinetics of recovery were investigated. The correlation of cell-mediated and humoral immune pictures was assessed by assaying immunoglobulins, splenocytes viability, phagocytic index, and Th1/Th2 cytokines. Results: The cultured BMMSCs counting were 4.21×104 cells/cm2 with 96.03% viability. Flow-cytometric analysis indicated positive CD90 (82%), CD105 (79%) and negative CD34 (0.37%), CD45 (0.42%), attesting to the suitability of the isolated BMMSCs for use in therapy. Transplantation of BMMSCs after albendazole administration significantly reduced the release of liver enzymes (p<0.05) indicating liver cellularity improvement. The ultrasonographic, macroscopic, and histopathological findings confirmed the biochemical results. Significant elevation in the levels of tumor necrosis factor (TNF)-α and interferon (INF)-γ with a decline in interleukin (IL)-4 was observed in the untreated model (p<0.05). However, albendazole treatment followed by BMMSCs therapy significantly lowered the release of TNF-α and INF-γ, associated with significant production of IL-4 and IL-10 (p<0.05). Conclusion: The final results indicated that the liver functions, histopathological findings, and immune parameters were aggravated after experimental T. vitulorum infection. Albendazole treatment followed by BMMSCs therapy was found to assist in regeneration of injured hepatic tissue. Besides, it appeared to modulate host defensive immune responses against T. vitulorum antigens. This work could define more clearly the events that manipulate the host immune, histopathological, and biochemical responses to minimize obstacles in using stem cell therapy in animal toxocariosis.
