A novel humanized mouse model to study mucosal HIV-1 transmission and prevention
Humanized mice have been critical for HIV-1 research, but are inefficient at mucosal HIV-1 transmission. We present a fetal tissue-independent model called CD34T+ with enhanced human leukocyte levels in the blood and improved T cell homing to the gut-associated lymphoid tissue. CD34T+ mice are highly permissive to intra-rectal HIV-1 infection, which can be prevented by infusion of broadly neutralizing antibodies. Therefore, CD34T+ mice provide a novel platform for mucosal HIV-1 transmission and prevention studies.
