How safe is a popular gene therapy vector
NettetIts safety can be substantively improved by an M Delta 51 deletion in the viral genome, and yet VSV (M Delta 51) induces a much greater, robust cellular inflammatory response in the host than wild-type VSV, which severely attenuates its oncolytic potency. NettetViral vectors are currently a delivery vehicle used in FDA-approved gene therapies. Non-viral techniques are currently being studied as a safe and effective way to deliver genetic material to cells for therapeutic effect.
