Many alternative and complementary therapies for cancer have been reported. The objective of the present work is to examine antitumor and immune-modulatory properties of dual-treatment based on levamisole (Lms) and/or taurine (Tau) in Ehrlich ascites carcinoma-bearing mice. In the current study, Lms (10 mg/kg; subcutaneously) and Tau (640 mg/kg; intragastrically) was administered alone or as a dual-treatment. Lms or Tau was administered in combination with cyclophosphamide (CTX) (100 mg/kg; intraperitoneal) in mice bearing Ehrlich ascites carcinoma. Treatment with CTX or (Lms plus Tau) significantly reduced the ascitic tumor cell count, percentage of tumor cell viability while elevated the tumor inhibition rate and apoptosis percentage compared to non-treated animals. Dual-treatment (Lms and CTX) or (Tau and CTX) significantly potentiated the reduction of the ascitic tumor cell count, viability and augmented the tumor inhibition rate and apoptosis percentage compared to CTX-treated mice. Dual-treatment of (Lms plus Tau), (Lms plus CTX) or (Tau plus CTX) altered splenocytes immunological profile of CD3+CD4+, CD3+CD8+, CD4+CD25+ and CD11b+Ly6G+ cells in order to achieve better immune surveillance against tumor cells. In conclusion, dual-treatments based on Lms and/or Tau are promising therapies for cancer, not only due to its abilities to induce apoptosis in the tumor cells and modulate the immune response against them, but also due to its capabilities to potentiate the chemotherapy anticancer efficacy and minimize its adverse effects.
