This　paper　is　devoted　to　develop　a　nonlocal　and　time-delayed　reaction-diffusion　model　for　HIV　infection　within　host　cell-to-cell　viral　transmissions.　In　a　bounded　spatial　domain,　we　study　threshold　dynamics　in　terms　of　basic　reproduction　number　R-0　for　the　heterogeneous　model.　Our　results　show　that　if　R-0　＜　1,　the　infection-free　steady　state　is　globally　attractive,　implying　infection　becomes　extinct,　while　if　R-0　＞　1,　virus　will　persist　in　the　host　environment.
