Scancell have not directly looked at this area in the Pre-clinical but Scancell is aware of what a CD4 can do hence inclusion in the SCIB1 and SCIB2 vaccine ...
we can picture a communication triangle in which tumor-specific CD4 cells activate NK cells via a DC bridge and/or NK cells help to sustain the CD4 response through the activation of DCs. A variation of this scenario comes from a previous report suggesting that CD4 T cells might also partner with tumor-infiltrating macrophages.17,22 At first glance, such a duo might seem less likely than that of the CD4/NK cell partnership, given that tumor-infiltrating macrophages have been shown to support tumor growth by promoting angiogenesis and tissue remodeling and repair.59,60 However, CD4 cells are effective educators of other cells: they can license DCs to activate CD8 killers,43 they can educate DCs to perpetuate oral tolerance,61 and they can induce B cells to switch to a different class of antibody. It is only a small step to suppose that tumor-specific CD4 cells could recognize tumor-infiltrating macrophages, via cross-presented tumor antigens, and alter their phenotype from “tumor-nurturing” to “tumor-rejecting.” Overall, it seems that CD4 T cells may partner with many different types of host cells to clear the tumor, something that CD8 cells may be less able to do.
