Lentivirus

a genus in the family Retroviridae containing 5 serogroups that reflect the host with which they are associated

Description
Among the primate lentiviruses are human immunodeficiency viruses 1 and 2, which are pathogens of major global importance. Based on lentiviruses, lentiviral vectors have been developed, which as of this writing appear the most effective and safest tool for gene therapy approaches to hemoglobinopathies, i.e. for the correction of congenital defects in hematopoietic stem and precursor cells.
