Definitions
- the present invention relates to polyclonal antibodies that specifically recognize and with great affinity to the two most important amyloid peptides, A ⁇ 40 and A ⁇ 42, as well as their use in the evaluation of both degradation activating drugs of the characteristic amyloid peptides of Alzheimer's disease as a drug that inhibits its formation.
- they can be useful for the evaluation of the activity of the enzymes involved in the processing of the precursor protein of said peptides or the activity of the enzymes involved in the degradation thereof, as well as of the assessment of the level of expression of the genes involved in all the machinery of events that lead to the deposit and formation of amyloid plaques, characteristic lesions of the brains of patients suffering from Alzheimer's disease.
- MNF neurofibrillar tangles
- intraneuronal neurofibrillar tangles are also present in other degenerative diseases, but the presence of amyloid deposits in both the interneuronal spaces (neuritic plaques) and in the surrounding microvasculature (vascular plaques) it seems to be characteristic of Alzheimer's. Of these, the neuritic plaques appear to be the most characteristic (Price, DL et al., Drug Development Research (1985) 5: 59-68).
- amyloid plaques The main component of these amyloid plaques is a 40-42 amino acid peptide called A ⁇ 4 amyloid peptide.
- the A ⁇ 4 amyloid peptide is a polypeptide originated by proteolysis from membrane glycoproteins called A ⁇ 4 amyloid peptide precursor proteins ( ⁇ APP). Being these precursor proteins of the amyloid peptide constituted by 695 to 770 amino acids, all of them being produced by the same gene.
- ⁇ APP A ⁇ 4 amyloid peptide precursor proteins
- the chicken embryo processes ⁇ APPs in such a way that A ⁇ 4 peptide is produced, due to the action of proteolytic enzymes that cause proteolysis of ⁇ APPs at a key site to produce A ⁇ 4, the proteolytic enzyme that cuts ⁇ APPs for produce A ⁇ 4 is called ⁇ -secretase.
- the present invention provides polyclonal antibodies, capable of specifically recognizing by any conventional immunological technique (western blot, immunohistochemistry, immunoprecipitation, ELISA, RIA, ...) of the presence of the amyloid peptides A ⁇ 40 and A ⁇ 42, obtained by mammalian immunization, preferably rabbits, with a protein conjugated to a peptide selected from a group consisting of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 4, optionally shortened by elimination of amino acid residues from the ends N-terminal and / or C-terminal, and optionally elongated by adding the appropriate amino acid residues to conjugate the protein.
- the peptide corresponds to SEQ ID NO 1, optionally elongated by adding the appropriate amino acid residues to conjugate the protein.
- the peptide corresponds to SEQ ID NO 2, optionally elongated by adding the appropriate amino acid residues to conjugate the protein.
- the peptide corresponds to SEQ ID NO 3, optionally elongated by adding the appropriate amino acid residues to conjugate the protein.
- the peptide corresponds to
- SEQ ID NO 4 optionally elongated by adding the appropriate amino acid residues to conjugate the protein.
- the preferred peptides are those of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3 and SEQ ID NO 4.
- This invention also provides a method for obtaining the aforementioned polyclonal antibodies by immunization of mammals, preferably rabbits, with a protein conjugated to a peptide selected from a group consisting of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 4, optionally shortened by elimination of the amino acid residues from the N-terminal and / or C-terminal ends, and optionally elongated by addition of the appropriate amino acid residues to conjugate the protein.
- a protein conjugated to a peptide selected from a group consisting of SEQ ID NO 1, SEQ ID NO 2, SEQ ID NO 3, SEQ ID NO 4, optionally shortened by elimination of the amino acid residues from the N-terminal and / or C-terminal ends, and optionally elongated by addition of the appropriate amino acid residues to conjugate the protein.
- the protein used for conjugation with the peptide is barnacle hemocyanin (KLH, Keyhole Limpet Hemocyanin in English).
- the mammals used, for their immunization with the protein conjugated to the peptide are rabbits.
- a new method for the evaluation of both degradation activating drugs of the amyloid peptides characteristic of Alzheimer's disease, and of drugs inhibiting their production, by the use of antibodies polyclonal described above.
- the method also serves to assess the activity of the enzymes (proteases) involved in the processing of the precursor protein of said peptides or the activity of the enzymes involved in the degradation thereof.
- This invention also provides a method for detecting the presence or absence of the amyloid peptides A ⁇ 40 and A ⁇ 42 in a sample, using the chicken embryo or any of the membranes or extra-embryonic liquids of the chicken embryonated egg, as an animal test model.
- a new method for the evaluation of both degradation activating drugs of the amyloid peptides characteristic of Alzheimer's disease, and of drugs that inhibit their production, by using the chicken embryo or any of the membranes or extraembryonic liquids of the chicken embryonated egg, as an animal test model.
- a new method for assessing the activity of enzymes (proteases) involved in the processing of the precursor protein of said peptides or the activity of enzymes involved in the degradation of the enzymes is provided. same, by using the chicken embryo or any of the membranes or extraembryonic liquids of the chicken embryo egg, as an animal test model.
- the method consists of inoculating the drug in the chicken embryonated egg, and by simple drip on the embryo itself or any of its membranes, either by injection into the vitellus (if the embryo is young) or yolk sac (if the embryo is older), in the amniotic sac, in the allantoic sac (in embryos of more than 6 days of incubation) or inside the embryo itself and, after the appropriate incubation time, the embryo and / or any of the extra-embryonic membranes or liquids are removed and the amount of amyloid peptides, characteristic of Alzheimer's disease, is analyzed, by conventional laboratory techniques for the quantification of peptides and proteins such as western blot, immunohistochemistry, immunoprecipitation, ELISA, RIA, HPLC, etc.
- the peptides were coupled to the barnacle hemocyanin protein (KLH, Keyhole Limpet Hemocyanin), via n-terminus, using the glutaraldehyde coupling agent.
- KLH barnacle hemocyanin protein
- the synthetic peptide was added and the 0.3% glutaraldehyde salutation was slowly added while stirring at room temperature.
- 1M glycine to block the non-reactive glutaraldehyde
- the peptide-protein conjugate was dialyzed against 3 liters of pH 8.5 borate buffer at a temperature of 4 ° C.
- the Peptide-KLH conjugate was stored at 4 ° C.
- the four polyclonal antibodies were generated by immunization of New Zealand White rabbits against the four KLH-coupled peptides that were used as immunogens.
- Each immunogen was injected into two rabbits, with five injections: the first intradermal injection of the peptide-KLH conjugate in PBS and emulsified in complete Freund's adjuvant and four more intramuscular, as a souvenir dose on days 14, 28, 49 and 80, of the same peptide-KLH conjugate in PBS but this time emulsified in incomplete Freund's adjuvant, control bleeding at 90 days being performed to detect the presence of antibodies.
- affinity antibodies were purified on a matrix composed of 1.5 ml of EMD-Epoxy activated material (Merck) to which 5mg of the corresponding peptide was added. .
- the purified fractions were stabilized in 0.1% BSA (Sigma) and stored at 4 ° C, with glycerol 20-50% being added as a cryoprotectant.
- Antibody titration by ELISA After affinity purification the antibody titer was determined by ELISA. For this, the antigen was placed on a Nunc Maxi Sorb ELISA plate at a rate of 50ng / 50 ⁇ l in PBS pH 7, and the donkey anti-IgG antibody conjugated to alkaline phosphatase was detected, using p-nitrophenyl phosphate (PNPP as substrate) ) in diethanolamine with 5mM MgCl 2 , pH 9.6 and developed at 2 hours.
- PNPP p-nitrophenyl phosphate
- the antibodies were generated using the different synthetic peptides described above coupled to KLH. These synthetic peptides contain a very small number of amino acids, which makes them very suitable for the chain production of homogeneous antibodies, with predefined epitopes.
- amino acids are abbreviated using the one-letter codes accepted in the field, in the form shown below:
- Trp tryptophan
