Answer #1

I shall draw a diagram which will help you understand the mechanism with the help of which cytotoxic t lymphocytes kill virus-infected cells

Activated Cytotoxic t cell receptor binds to MHC I peptide complex Initiates Apoptosis Creates nuclear blebbing Virus-infected Cell morphology alteration Virus-infected cell DNA fragmentation Shedding of membrane-bound vesicles Shrinking of cell Virus-infected cell self-destruction process completed.

Thus the process of apoptosis is completed.

Q2. A virus must replicate in the infected cell and orchestrate the assembly of virion constituents to produce progeny viruses and propagate itself. This often happens at the expense of the infected cell. A radical but ultimately effective response to stop virus replication is for the infected cell to self-destruct via apoptosis. Some viruses have evolved strategies to overcome this. A. Some Coronoviruses does it by inducing apoptosis of the killer lymphocyte cells. How does apoptosis of killer lymphocyte cells...
