Abstract: The present invention relates to pseudotyped retrovirus-like particles or retroviral vectors comprising both engineered envelope glycoproteins derived from a virus of the Paramyxoviridae family fused to a cell targeting domain and fused to a functional domain. The present invention also relates to the use of said pseudotyped retrovirus-like particles or retroviral vectors to selectively modulate the activity of specific subsets of cells, in particular of specific immune cells. These pseudotyped retrovirus-like particles or retroviral vectors are particularly useful for gene therapy, immune therapy and/or vaccination.
