abstract：:HIV-1 infection is characterized by life-long viral persistence and continued decline of helper CD4 T cells. The new generation of humanized mouse models that encompass RAG-hu, hNOG and BLT mice have been shown to be susceptible to HIV-1 infection and display CD4 T cell loss. Productive infection has been demonstrated...
