List nine cytopathic effects of viral infections.
1: Inhibition of macromolecular synthesis
2: Release of lysosome contents
3: Inclusion bodies (site of viral synthesis/assembly)
4: Formation of fused cells (Syncytium)
5: Change in cell function - e.g. when measles virus attaches to CD46 cells they reduce IL-12 production
6: Some viral infected cells produce interferon
7: Viral infections can induce antigenic changes on host cell surface
8: Changes to host chromosomes, oncogenes may be added
9: Cancer causing viruses inhibit "contact inhibition" between host cells thus promoting cancer.
