Selective replication of an oncolytic virus within an infected tumor cell might be engineered in multiple ways to optimize the kinetics, type, and level of resultant immune response. The approaches covered in this perspective are summarized here, along with their range of activity (local acting within the tumor, or systemic activity) and whether immune activation or blocking of immune suppression are involved. Ideal combination approaches would be predicted to involve components of different quadrants in the figure.
