The present invention relates to lentiviral particles which have been pseudotyped with Nipah virus (NiV) fusion (F) and attachment (G) glycoproteins (NiVpp-F/G). Additionally, the present invention relates to truncated NiV-F glyocproteins useful in producing such NiVpp lentiviral particles, as well as to additional variant peptides which enhance activity. Further, the present invention relates to methods of using such lentiviral particles or sequences, for example in the treatment of cancer or CNS disorders.
