This allows the retrovirus to implant nearby a cellular oncogene.
Omnius then launches capsules containing the retrovirus to infect the planets inhabited by the hapless humans.
I understand that there is a considerable scientific literature on the possible effects of retroviruses on elements of the immune system.
The main reason for this lack of efficiency in nonproliferating cells, similar to the problems faced by retrovirus, is thought to be the barrier of the intact nuclear membrane.
Lack of evidence for infection with known human and animal retroviruses in patients with chronic fatigue syndrome.
