A T- cytotoxic cell can be induced to mount a cytotoxic attack on a virus-infected cell if it binds to a cell displaying
In cell biology, cellular compartmentalization and cell cycle dictates that SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Therefore MHC I bearing foreign antigen. is correct as it aligns with membrane trafficking and cell cycle control, supported by mechanistic studies and conserved across related systems.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 17, Cell Cycle and Regulation, explains Cdc2, cyclins, P53, proteasomes, Hayflick limit, primary culture and immortalization mechanisms governing proliferation.
