A virus closely related to HTLV-I, human T-lymphotropic virus 2 (HTLV-II or HTLV-2) shares approximately 70% genomic homology (structural similarity) with HTLV-I. It was discovered by Robert Gallo and colleagues.[1][2]
HTLV-2 is prevalent in Africa and among Indigenous peoples in Central and South America, as well as among drug users in Europe and North America.[3] It can be passed down from mother to child through breast milk, and even genetically from either parent.
HTLV-II entry in target cells is mediated by the glucose transporter GLUT1.[4]
