Abstract
An adenovirus or adenovirus-like particle which has a modified binding specificity conferred by a binding moiety. The binding moiety is heterologous to the adenovirus and is incorporated as a fusion protein with the fiber protein. This allows the adenovirus or adenovirus-like particle to bind to a target cell which is not the natural host cell of the virus. The penton fiber is modified by the insertion or, deletion, or substitution of amino acid residues, that disrupt the host-cell binding function so that the adenovirus or adenovirous like particle does not bind the natural host cell.

An adenovirus, or adenovirus-like particle, haivng a penton fibre comprising a modified binding specificity conferred by a binding moiety which is heterologous to the adenovirus and is incorporated as a fusion protein with the fibre protein allowing the adenovirus or adenovirus-like particle to bind to a target cell which is not the natural host cell of the virus, characterized in that the said penton fibre is modified by the insertion or deletion or substitution of amino acid residues that disrupt the host-cell binding function so that the adenovirus or adenovirus-like particle is substantially incapable of binding the natural host cell.
An adenovirus or adenovirus-like particle having a penton fibre, comprising a modified binding specificity conferred by a binding moiety allowing the adenovirus or adenovirus-like particle to bind to a target cell, characterized in that the penton fibre protein is substantially incapable of binding the natural host cell and the binding moiety is fused to the penton fibre protein at any one or more of the junctions of the repetition units of the shaft.
