What are oncolytic viruses?
Oncolytic viruses are engineered viruses that selectively infect and kill cancer cells while sparing normal cells.
How does the protocol improve cancer immunotherapy?
It provides a method to create versatile oncolytic vectors that can modulate immune responses against tumors.
What is a bispecific T cell engager?
A bispecific T cell engager is a type of protein that can simultaneously bind to T cells and cancer cells, enhancing the immune response against tumors.
Why is visual assessment important in this protocol?
Visual assessment of syncytia formation is crucial for determining the optimal time to harvest the virus during propagation.
Can this method be adapted for other viruses?
Yes, the protocol is designed to be adaptable for various vector platforms and transgenes.
