| Popis | Immunotherapy represents a revolutionary advancement in cancer treatment, which has traditionally focused on T cells; however, the role of B cells in cancer immunotherapy has gained interest because of their role in antigen presentation, antibody production, and cytokine release. In this study, we examined the role of B cells in previously developed intratumoral MBTA therapy (mannan-BAM, TLR ligands, and anti-CD40 antibody) in murine models of MTT pheochromocytoma. The results indicated that B cells significantly enhance the success of MBTA therapy, with wild-type mice exhibiting a lower tumor incidence and smaller tumors compared with B cell-deficient mice. Increased IL-6 and TNF-alpha levels indicated severe inflammation and a potential cytokine storm in B cell-deficient mice. Neutralization of TNF-alpha ameliorated these complications but resulted in increased tumor recurrence. The results highlight the important role of B cells in enhancing the immune response and maintaining immune homeostasis during MBTA therapy. Our findings offer new insights into improving therapeutic outcomes. |
