The present invention relates to viral capsid proteins, as a medicament for the treatment of a pathologic disorder. More particularly, the invention relates to the viral capsid proteins VP1, VP2 and VP3, preferably, the SV40 VP1 or any peptide, fragment, mutant, derivative and mixtures thereof or of virus-like particles (VLP’s) comprising the same, as the active ingredient in compositions for the treatment of pathologic disorders, preferably disorders associated with inactivation of cellular proteins involved with quality control processes, particularly, chaperones. The invention further provides methods for the treatment of such disorders and the use of the SV40 capsid proteins for the preparation of pharmaceutical compositions.
