1. A recombinant herpes simplex virus (HSV) particle having at least one protein on its surface, comprising:
(a) an altered viral surface protein, wherein the alteration reduces binding of the viral surface protein to a sulfated proteoglycan; and
(b) an altered gD, wherein the alteration reduces binding of gD to one or more of its cellular receptors, said alteration comprising
(i) a heterologous peptide ligand on the surface of the recombinant HSV particle forming a fusion protein with the altered gD; and
(ii) a V34S amino acid substitution;
wherein said recombinant HSV particle preferentially binds to cells expressing a binding partner to said heterologous peptide ligand.
