Tumor-targeted IL-2 amplifies T cell-mediated immune response induced by gene therapy with single-chain IL-12.

abstract：:Pathologic ocular neovascularization commonly causes blindness. It is critical to identify the factors altered in pathologically proliferating versus normally quiescent vessels to develop effective targeted therapeutics. MicroRNAs regulate both physiological and pathological angiogenesis through modulating expression ...
