We have always lived in a tough, dynamic neighbourhood-rats, radon,retrovirus-and we always will.

One major evolutionary question that is still unanswered is the nature of the relationships among different types of transposon and between retrotransposons and retroviruses.

In the future, they might be of benefit in sheltering endogenous genes fromretrovirus-induced transcription.

The evolutionary relationship between retroviruses and retroelements is also becoming clearer.
From theCambridge English Corpus
Retrovirus-like elements transcribe, their transcript is spliced by the host and two to three proteins required for transposition are translated from it.

Lack of evidence for infection with known human and animal retroviruses in patients with chronic fatigue syndrome.

The main reason for this lack of efficiency in nonproliferating cells, similar to the problems faced byretrovirus, is thought to be the barrier of the intact nuclear membrane.
From theCambridge English Corpus
I understand that there is a considerable scientific literature on the possible effects of retroviruses on elements of the immune system.
