Host Restriction Factors Blocking Retroviral Replication

Retroviruses are highly successful intracellular parasites, anti as such they are found in nearly all branches of life. Some are relatively benign, but many are highly pathogenic anti can cause either acute or chronic diseases. Therefore, there is tremendous selective pressure on the host to prevent retroviral replication, and for this reason cells have evolved a variety of restriction factors that act to inhibit or block the viruses. This review is a survey of the best-characterized restriction factors capable of inhibiting retroviral replication anti aims to highlight the diversity of strategies used for this task.
