Gibbon-ape leukemia virus (GaLV) is an oncogenic, type C retrovirus that has been isolated from primate neoplasms, including the white-handed gibbon and woolly monkey.[1] The virus was identified as the etiological agent of hematopoietic neoplasms, leukemias, and immune deficiencies within gibbons in 1971, during the epidemic of the late 1960s and early 1970s. Epidemiological research into the origins of GaLV has developed two hypotheses for the virus' emergence. These include cross-species transmission of the retrovirus present within a species of East Asian rodent or bat, and the inoculation or blood transfusion of a MbRV-related virus into captured gibbons populations housed at medical research institutions.[2] The virus was subsequently identified in captive gibbon populations in Thailand, the US and Bermuda.[3]
GaLV is transmitted horizontally by contact with excretory products of infected gibbons.[4] However, it is also hypothesised to be vertically transmitted via parent-progeny transmission.[5] Phylogenetic analysis have revealed 7 strains of GaLV; GaLV-SF, GaLV-SEATO, GaLV-BR, GALV-X, GaLV-Mar, GaLV-H and SSV, which have emerged as a result of selection pressures from the host immune system.[3] Recently, full genome sequences of these strains have been made available which broadens the possibilities for GaLV's utility as a viral vector in gene transfer.[6]
