{Reference Type}: Journal Article {Title}: Characterizing the phenotypic and genetic changes of pre-epidemic HIV-2 group F virus following serial passage in humanized mice. {Author}: Curlin JZ;Schmitt K;Remling-Mulder L;Tibbitts CV;O'Connor S;Marx P;Akkina R; {Journal}: J Med Primatol {Volume}: 52 {Issue}: 5 {Year}: 2023 10 1 {Factor}: 0.821 {DOI}: 10.1111/jmp.12674 {Abstract}: HIV-2 Group F virus with an origin in NHPs was isolated from only two individuals. Two serial passages in hu-mice showed increased viral loads, CD4+ T cell decline and nonsynonymous genetic changes showing its capacity for further evolution, and spread in the human.
