IL4 and neoplasm: Splenocytes from VSSP-treated or untreated MCA203 TB mice were in vitro stimulated with bone marrow (BM)-derived DCs pulsed with tumor lysates, obtained from MCA203 or 3LL-D122 (negative control) cell lines, and the production of IFN-γ, IL-4 and IL-17 by CD4+ T cells was measured by intracellular staining.
