Abstract
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.
Claims19
A pharmaceutical composition, in dosage form, comprising a pharmaceutically acceptable carrier and an active ingredient, wherein said active ingredient consists of at least one capsid protein selected from the group consisting of (1) a wild-type SV40 VP1 capsid protein or pentamer thereof, (2) a 65 amino acid truncated mutant of the SV40 VP1 capsid protein deleted in its carboxy terminal arm, and (3) a virus-like particle (VLP) consisting of at least one wild-type SV40 VP1 capsid protein of (1) or truncated mutant of (2), wherein the composition is DNA-free.
A pharmaceutical composition for rescuing cells from any one of oxidative stress and apoptosis and for inducing survival pathways in said cells, wherein said cells are of a subject suffering from ARF (Acute Renal Failure), said composition being in dosage form and comprising a pharmaceutically acceptable carrier and an active ingredient, wherein said active ingredient consists of a therapeutically-effective amount of at least one capsid protein selected from the group consisting of (1) a wild-type SV40 VP1 capsid protein or pentamer thereof, (2) a 65 amino acid truncated mutant of a SV40 VP1 capsid protein deleted in its carboxy terminal arm, and (3) a virus-like particle (VLP) consisting of at least one wild-type SV40 VP1 capsid protein of (1) or said truncated mutant of (2), wherein said composition is DNA-free.
A pharmaceutical composition, in dosage form, comprising a pharmaceutically acceptable carrier and at least one capsid protein consisting of a 65 amino acid truncated mutant of a wild-type SV40 VP1 capsid protein deleted in its carboxy terminal arm or a virus-like particle (VLP) consisting of at least one said truncated mutant.
A pharmaceutical composition for rescuing cells from any one of oxidative stress and apoptosis and for inducing survival pathways in said cells, wherein said cells are of a subject suffering from ARF (Acute Renal Failure), said composition comprising a pharmaceutically acceptable carrier and, as an active ingredient, a therapeutically-effective amount of at least one 65 amino acid truncated mutant of a wild-type SV40 VP1 capsid protein deleted in its carboxy terminal arm or a virus-like particle (VLP) consisting of at least one said truncated mutant.
A method for treatment of Acute Renal Failure (ARF) comprising administering to a subject in need thereof, as an active ingredient, a therapeutically-effective amount of at least one wild-type SV40 VP1 capsid protein, or a 65 amino acid truncated mutant of the SV40 VP1 capsid protein deleted in its carboxy terminal arm, or virus-like particles (VLPs) comprising at least one wild-type SV40 VP1 capsid protein or the truncated mutant, or a composition comprising the same.
A method for treatment of ARF (Acute Renal Failure) comprising administering to a subject in need thereof a therapeutically-effective amount of at least one wild-type SV40 VP1 capsid protein or a composition comprising the same.
A method for treatment of ARF (Acute Renal Failure) comprising a step of administering to a subject in need thereof a therapeutically-effective amount of at least one virus-like particle (VLP) or pentamer comprising a wild-type SV40 VP1 capsid protein or a composition comprising the same.
A method for rescuing cells from oxidative stress or apoptosis, and inducing survival pathways in said cells, wherein said cells are cells of a subject suffering from ARF (Acute Renal Failure), comprising contacting cells undergoing oxidative stress or apoptotic process, with an effective amount of at least one wild-type SV40 VP1 capsid protein, or a 65 amino acid truncated mutant of the SV40 VP1 capsid protein deleted in its carboxy terminal arm, or virus-like particles (VLPs) comprising at least one wild type SV40 VP1 capsid protein or the truncated mutant, or a composition comprising the same.
