Definitions
- compositions and methods for the treatment or detection of neurodegenerative pathologies are provided.
- the present invention relates to the field of biology, genetics and medicine. It relates in particular to new methods for the detection, characterization and / or treatment (or management) of neurodegenerative pathologies, in particular of amyotrophic lateral sclerosis.
- the invention also relates to methods for the identification or screening of active compounds in these pathologies.
- the invention also relates to the compounds, genes, cells, plasmids or compositions useful for the implementation of the above methods.
- the invention describes in particular the role of calcineurin in these pathologies and its use as a therapeutic, diagnostic or experimental target.
- Amyotrophic lateral sclerosis (SAL or ALS for Amyotrophic Lateral Sclerosis) is a neurodegenerative disease, associated with different types of inclusions such as Lewis bodies and characterized by apoptosis of spinal and cortical motoneurons, the fatal outcome of which is sometimes associated with frontal dementia.
- Sporadic forms without any mutation described, coexist with familial forms (FALS) associated with mutations in the SOD1 gene coding for superoxide dismutase.
- FALS familial forms
- the majority of cases are sporadic, familial forms (FALS) being very rare. It is likely that a long asymptomatic period precedes the onset of clinical symptoms which are varied and whose classification is complex.
- mice which express the human SOD1 gene carrying one of the mutations prevailing in FALS (mutation G93A) are available from Jackson Laboratory, subject to obtaining a license to use from NorthWestem University. This model reproduces in 120 days the fatal outcome of the disease with symptoms comparable to those of human disease.
- the appearance of ALS symptoms linked to the G93A mutation in SOD1 is not the consequence of a reduction in superoxide dismutase activity but of a gain in function which increases the capacity of the enzyme to generate radicals free.
- the molecular events that govern the different stages of ALS are poorly understood.
- Identifying the different specific molecular events of the different phases of the pathology must make it possible to identify new therapeutic targets as well as new diagnostic markers.
- One of the most effective approaches to achieve this identification is to identify genes and proteins whose expression characterizes a pathophysiological state.
- the present invention now describes the identification of genetic events involved in the phenomena of excitotoxicity and neuronal death.
- the present invention thus provides new therapeutic and diagnostic approaches for the pathologies associated with these phenomena, as well as new targets for the identification of active compounds.
- RNA extracted from brain and spinal cord samples without prior isolation of the neurons was carried out using RNA extracted from brain and spinal cord samples without prior isolation of the neurons in order to take into account a maximum of alternative splicing events linked to the development of the pathology.
- This analysis was carried out by qualitative differential screening according to the DATAS technique (described in application No. WO99 / 46403), which has unequaled advantages.
- the present patent application stems in particular from the construction by the applicant of a directory of splicing alterations in the brains of 60 day old ALS model animals.
- This repertoire which contains more than 200 distinct sequences, involves key players in the phenomenon of excitotoxicity such as potassium channels and the NMDA receptor.
- Sequences derived from RNAs coding for proteins involved in the stress response, including heat shock proteins, are also part of this repertoire, highlighting the implication of this response in the early phases of ALS.
- An alteration in energy metabolism clearly appears to affect the cortical motor neurons of animals that develop the pathology. For example, intron 6 of the mitochondrial form of creatine kinase is isolated specifically from messenger RNAs expressed under pathological conditions in animals aged 60 days.
- RNA RNA of the calcineurin catalytic subunit.
- This fragment corresponds to an exon fragment specifically present in the control animals and therefore specifically deleted in transgenic animals for SOD1G93A at the 60-day stage.
- This fragment covers the nucleotides 1 348 to 1 579 referenced from the ATG.
- This region is essentially coding and contains an auto-inhibiting domain of the enzyme located at the C-terminal end of the enzyme.
- This short isoform is distinguished from the long form by a deletion of nucleotides 1341 to 1741 (inclusive) and therefore of amino acids 447 to 524, the calcineurin stop codon corresponding to nucleotide 1 641 (the complete calcineurin sequence and its DNA, of murine or human origin, is available on a database, in particular GeneBank).
- the cDNA sequence coding for human calcineurin (2 119 bp) is represented on the sequence SEQ ID No. 1.
- the protein sequence is represented on the sequence SED ID No. 2. Residues 348 to 368 of SEQ ID No.
- sequences SEQ ID No. 3 and 4 represent, respectively, the nucleic acid sequence and the amino acid sequence of the splicing variant of calcineurin, according to the invention.
- the deletion of nucleic acid residues 1341 to 1741 inclusive results in a deletion of the C-terminal amino acids from residue 447, and the creation of a C-terminal end of sequence KLYFGEGGD (residues 448 to 456 of SEQ ID No. 4).
- calcineurin auto-inhibitory domain corresponds to amino acids 467 to 490 and that the absence of this domain results in constitutive activation of calcineurin.
- Calcineurin is involved in the relay of signaling pathways which depend on calcium and calmodulin.
- the interaction of calmodulin with calcineurin stimulates the activity of the latter.
- Deletion of the auto-inhibitory domain of calcineurin increases the basal level of activity of this enzyme but keeps it susceptible to activation by calmodulin.
- the present invention therefore describes an original and new molecular event (splicing), which results in constitutive activation of calcineurin and which is correlated with the phenomenon of excitotoxicity and / or neuronal death.
- the invention also shows, for the first time, that a constitutive activation of calcineurin is associated with the early stages of ALS. Calcineurin therefore constitutes a new and important therapeutic target in the development of therapeutics for these pathologies, which can be used in particular at the early stages of their development, and which is intended for the true molecular bases of the pathology and not for the associated symptoms or immune components.
- a first object of the invention lies more particularly in the use of a nucleic acid comprising all or part of a sequence derived from the messenger RNA of the catalytic subunit of calcineurin for the implementation of a method of diagnosing or detecting a situation of neuronal stress and more particularly the situation of excitotoxicity.
- the invention generally resides in the use of a nucleic acid complementary to all or part of the calcineurin gene or messenger, for the detection of pathological events of the excitotoxicity, stress or neuronal death type, etc.
- the invention is particularly intended for the detection, screening, diagnosis or characterization of an excitotoxicity associated with the early forms of neurodegenerative diseases, in particular ALS, Parkinson's disease or Alzheimer's disease.
- nucleic acids capable of demonstrating a deleted form of the calcineurin mRNA, in particular a splicing variant, in particular, in which an auto-inhibitory domain is deleted, in particular the bases. 1341 to 1741 (or the corresponding region of the gene or human DNA).
- the invention indeed shows the existence of splicing events affecting the calcineurin gene, associated with the development of neuronal excitotoxicity, and proposes methods of detection or screening for dysfunctions based on the demonstration of the presence of these forms spliced in biological samples.
- the nucleic acid comprises all or part of the sequence coding the auto-inhibitory domain of calcineurin (between nucleotides 1401 and 1503 from ATG, for the murine form, or homologous residues in the human sequence , for example amino acids 467-490 of the sequence SEQ ID NO: 2), or of the sequence resulting from the junction between the non-deleted regions, or a sequence complementary to these.
- the invention uses a nucleic acid complementary to a region included in a following sequence:
- the complementarity is preferably perfect to ensure better specificity of hybridization. However, it is understood that certain mismatches may be tolerated.
- the nucleic acid used for the implementation of the above methods can be DNA or RNA, preferably DNA of synthetic origin. It preferably comprises from 10 to 500 bases, typically from 10 to 100 bases. It is understood that a longer nucleic acid can be used, if desired, although this is not preferred.
- the nucleic acid is advantageously a single-stranded DNA, from 10 to 500 bases, complementary to at least one region of the sequence coding for the autoinhibitory domain of calineurin or of the sequence resulting from splicing affecting at least part of this area.
- the nucleic acid can be labeled, for example by radioactive, enzymatic, luminescent, fluorescent, chemical, etc.
- a biological sample of a subject, containing a nucleic acid is brought into contact in vitro with a nucleic acid as defined above, and the formation of a hybrid.
- the biological sample can be a sample of blood, fluid, cell, tissue, etc.
- the nucleic acid can be immobilized on a support, of the glass, silica, nylon type, etc.
- the invention also relates to methods of detection, assay, screening, diagnosis, etc. in vitro, using an antibody specific for a spliced form of calcineurin, for example an antibody specific for the KLYFGEGGD polypeptide region.
- this domain is specific for a new form of calcineurin and does not exist in wild-type calcineurin. Antibodies directed against this domain therefore make it possible to demonstrate, by conventional immunological methods, the presence of a splicing variant and therefore of a predisposition or of the initiation of a phenomenon of neuronal excitotoxicity.
- the antibodies can be prepared by any technique known to those skilled in the art.
- An object of the invention also resides in an antibody binding a polypeptide of sequence SEQ ID NO: 4.
- the binding is preferably a selective binding, the antibody does not specifically recognize the calcineurin of sequence SEQ ID NO: 2.
- Another object of the invention resides in an antibody capable of binding the KLYFGEGGD sequence.
- Another object of the invention is an antibody produced by immunization with a polypeptide comprising the sequence KLYFGEGGD or an immunogenic fragment thereof.
- Antibodies can be polyclonal or monoclonal. It can also be fragments or derivatives of such antibodies, in particular fragments or derivatives of such antibodies having the same antigenic specificity, such as, for example, Fab, Fab'2, CDR fragments, humanized antibodies, single chain antibody (ScFv), etc. Antibodies can be produced in a conventional manner, by immunization with a polypeptide as defined above, and recovery of the serum (polyclonal) or of the spleen cells (to make hybridomas by fusion with an appropriate line).
- Fab or F (ab ') 2 fragments can be produced for example according to Riechmann et al., 1988, Nature 332, 323-327.
- the antibodies according to the invention can be coupled to different heterologous groups, such as markers, toxins from therapeutic agents, etc.
- markers such as diphtheria or botulinum toxin
- therapeutic agents are cytokines, growth factors, trophic factors, etc.
- the antibodies of the invention can be used in diagnosis or in therapy, as well as for the purification of the antigen. They can also be used for the screening of active compounds.
- the invention is applicable to the diagnosis or detection of various pathologies such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, Huntington's chorea or cerebral ischemia. It can be used for early detection, highlighting a predisposition, choosing and adapting a treatment, monitoring the evolution of the pathology, etc. It is particularly suitable for the early detection of multiple sclerosis.
- Another object of the invention lies in the use of a compound capable of inhibiting or reducing the expression or the activity of calcineurin, for the preparation of a composition intended for the treatment of neurodegenerative diseases, in particular in early phase, more preferably to reduce the excitotoxicity of the early neuron associated with neurodegenerative diseases such as ALS, Alzheimer or Parkinson.
- treatment designates preventive, curative, palliative treatment, as well as the management of patients (reduction of suffering, improvement of lifespan, slowing down the progression of the disease ), etc.
- the treatment can also be carried out in combination with other agents or treatments, in particular addressing late events in the pathology, such as caspase inhibitors or other active compounds.
- Another object of the invention resides in the use of a compound capable of inhibiting (preferably selectively) the expression or the activity of calcineurin of sequence SEQ ID No. 4 for the preparation of a composition intended to reduce neuronal excitotoxicity.
- the compound is an antisense nucleic acid, capable of inhibiting the transcription of the calcineurin gene or the translation of the corresponding messenger.
- the antisense nucleic acid may comprise all or part of the calcineurin gene sequence, a fragment thereof, the calcineurin messenger, or a sequence complementary thereto.
- the antisense can in particular comprise a region complementary to the form of splicing identified, and inhibit (or reduce) its translation into protein. This antisense thus comprises, by way of example, a sequence complementary to nucleotides 1333 to 1347 of SEQ ID No. 3.
- the compound is a peptide or an antibody specific for a spliced form of calcineurin. It may especially be a peptide comprising the sequence KLYFGEGGD or an antibody specific for the protein of sequence SEQ ID No. 4, and not recognizing the protein SEQ ID No. 2.
- the compound is a chemical compound, of natural or synthetic origin, in particular an organic or inorganic molecule, of vegetable, bacterial, viral, animal, eukaryotic, synthetic or semi-synthetic origin, capable of modulating the expression or activity of calcineurin.
- the compound is chosen from FK506 and cyclosporin A.
- calcineurin inhibitors have been described in the prior art. Some of these are commercially available drugs. This is the case of tacrolimus (or FK506) and cyclosporine A. These two compounds are immunosuppressants which bind to immunophilins, respectively the protein FKBP12 (FK506 binding protein 12) and cyclophilin A. Inhibition calcineurin, during the administration of these compounds, takes place by the formation of a complex between the compound, the immunophilin which it targets and the catalytic subunit of calcineurin. These immunophilins are peptidyl-prolyl-cis / trans-rotamases whose activity is also inhibited by their chemical ligands.
- the present invention therefore provides, for the first time, calcineurin as a therapeutic target for the treatment of molecular events associated with excitotoxicity.
- the invention can be used to inhibit or reduce neuronal excitotoxicity in the early phase of neurodegenerative diseases. It is applicable in particular to the treatment of Alzheimer's disease, of the disease of Parkinson's, multiple sclerosis, Huntington's chorea or cerebral ischemia.
- the invention relates to methods of treating ALS comprising administering to a subject an inhibitor compound as described above.
- the invention also relates to methods for reducing neuronal excitotoxicity comprising the administration to a subject of an inhibitor compound as defined above.
- the invention also relates to methods of treating ALS or neuronal excitotoxicity comprising the administration of a compound selectively inhibiting the expression or activity of calcineurin of sequence SEQ ID No. 4.
- the methods of the invention are used for the early phase treatment of neurodegenerative diseases.
- the administration can be carried out by any method known to a person skilled in the art, preferably by injection, typically by intraperitoneal, intra-cerebral, intravenous or intra-arterial route. These injected doses can be adapted by those skilled in the art. Typically, from about 0.01 mg to 100 mg / kg are injected, for inhibiting compounds of a chemical nature, such as FK506. For compounds such as antibodies, doses of 1 mg to 100 mg can be used. For nucleic compounds, the doses can vary for example between 0.01 mg and 100 mg per dose. It is understood that repeated injections can be carried out, possibly in combination with other active agents or any pharmaceutically acceptable vehicle (e.g., buffers, saline, isotonic solutions, in the presence of stabilizing agents, etc.)
- any pharmaceutically acceptable vehicle e.g., buffers, saline, isotonic solutions, in the presence of stabilizing agents, etc.
- cyclosporine A for the preparation of a composition intended to inhibit the activity of calcineurin in patients suffering from ALS
- FK506 for the preparation of a composition intended to inhibit the activity of calcineurin in patients suffering from ALS.
- Other subjects of the invention relate to methods of selection, identification, or characterization of compounds active on pathologies associated with excitotoxicity, or with neuronal stress, comprising bringing test compounds into contact with a cell expressing a variant d splicing of calcineurin lacking an auto-inhibitory domain, and the identification of compounds inhibiting the expression or activity of this protein.
- the methods can be implemented with different cell populations, such as primary cells or cell lines of mammalian origin (human, murine, etc.).
- cells which do not naturally express calcineurin are used, transfected with a nucleic acid encoding the desired variant. In this way, the selectivity of the method is increased.
- the screening methods can also be carried out in a cell-free system, by measuring the capacity of test compounds to bind the desired calcineurin variant.
- Another subject of the invention relates to a polypeptide derived from calcineurin, lacking the auto-inhibitory domain, in particular amino acids 467-490, preferably 467-521.
- This polypeptide can be of varied origin, in particular murine, human, synthetic or semi-synthetic, etc.
- a specific example of such a polypeptide comprises the sequence SEQ ID No. 4 or a region of this polypeptide comprising at least residues 441 to 456.
- Another subject of the invention is a polypeptide comprising the sequence KLYFGEGGD (residues 448-456 of SEQ ID NO: 4) or an immunogenic fragment thereof, preferably comprising at least 5 contiguous amino acids.
- Another subject of the invention relates to any nucleic acid encoding a polypeptide as defined above, the vectors containing it, recombinant cells, and uses.
- the vector may be a plasmid or a viral vector, such as for example a vector derived from an adenovirus, a retrovirus (including an Ientivirus), an AAV, a herpes virus, etc.
- the vector can comprise a promoter ensuring a constitutive or regulated expression (eg, inducible), ubiquitous or specific for tissues, strong or weak. It can be a promoter of a domestic gene (PGK, albumin, apolipoprotein), a promoter ensuring specific expression in nerve cells (GFAP, etc.) or a viral promoter (CMV-IE , LTR-RSV, etc.).
- a promoter ensuring a constitutive or regulated expression (eg, inducible), ubiquitous or specific for tissues, strong or weak. It can be a promoter of a domestic gene (PGK, albumin, apolipoprotein), a promoter ensuring specific expression in nerve cells (GFAP, etc.) or a viral promoter (CMV-IE , LTR-RSV, etc.).
- the compound FK506, but not Riluzole protects the primary neurons of cerebellar granules against the excitotoxicity induced by NMDA / Serine.
- the differential qualitative analysis was carried out using poly adenylated RNA (poly A +) extracted from samples of animal brains corresponding to the different stages, without prior isolation of the neurons in order to take into account a maximum of alternative splices linked to the development of pathology.
- poly A + poly adenylated RNA
- Poly A + RNAs are prepared according to techniques known to those skilled in the art. It may in particular be a treatment with agents chaotropics such as guanidium thiocyanate followed by extraction of total RNA by means of solvents (phenol, chloroform for example). Such methods are well known to those skilled in the art (see Maniatis et al., Chomczynsli et al., Anal. Biochem. 162 (1987) 156), and can be readily practiced using commercially available kits. From these total RNAs, poly A + RNAs are prepared according to conventional methods known to those skilled in the art and offered by commercial kits. These poly A + RNAs serve as a template for reverse transcription reactions using reverse transcriptase.
- agents chaotropics such as guanidium thiocyanate
- solvents phenol, chloroform for example
- reverse transcriptases lacking RNase H activity are used which make it possible to obtain first strands of complementary DNA of sizes larger than those obtained with conventional reverse transcriptases.
- Such reverse transcriptase preparations without RNase H activity are commercially available.
- the poly A + RNAs as well as the single stranded cDNAs are prepared from transgenic animals (T) and syngeneic control animals (C).
- hybridizations of mRNA are carried out with cDNAs (T) and reciprocal hybridizations of mRNA (T) with cDNAs (C).
- RNA sequences not paired with complementary DNA are released from these heteroduplexes under the action of RNase H, this enzyme degrading the paired RNA sequences.
- RNase H this enzyme degrading the paired RNA sequences.
- These unpaired sequences represent the qualitative differences which exist between RNAs which are otherwise homologous to one another. These qualitative differences can be localized anywhere on the RNA sequence, as well in 5 ′, 3 ′ or inside the sequence and in particular in the coding sequence. Depending on their location, these sequences can be not only modifications of splicing but also the consequences of translocations or deletions.
- the RNA sequences representing the qualitative differences are then cloned according to techniques known to those skilled in the art and in particular those described in the patent for the DATAS technique.
- sequences are grouped within cDNA banks which constitute differential qualitative banks.
- One of these banks contains exons and introns specific to the healthy situation; the other banks contain the splicing events characteristic of the pathological conditions.
- the differential expression of the clones was verified by hybridization with probes obtained by reverse transcription from messenger RNA extracted from the different situations studied. The differential hybridization clones were retained for further analysis.
- the sequences identified by DATAS correspond to introns and / or exons expressed in a differential manner by splicing between the pathological situations and the healthy situation. These splicing events may be specific to a given stage in the development of the pathology or characteristic of the healthy state.
- the compound is administered intraperineally, at different doses, according to protocols known to those skilled in the art and derived from the protocols used to take advantage of their immunosuppressive properties, from animals 45 days of age.
- FK506 protects primary cultures of neurons against excitotoxicity.
- FK506 works by binding to an immunophilin: FKBP12. This protein is endowed with a rotamase activity which is inhibited by FK506.
- FKBP12 when linked to FK506 acquires the property of inhibiting the activity of calcineurin.
- the implication of calcineurin inhibition in the specificity of this effect is underlined by the fact that an immunosuppressant which acts on the rotamase activities of immunophilins, rapamycin, has no effect on the model studied.
- FK506 protects by 50% against the toxicity induced by the NMDA / Ser treatment.
- the FK506 provides protection of almost 80%.
- concentrations such as 10 ⁇ M for example, the protection is not more important, a toxicity specific to large doses of FK506 being manifested.
- riluzole which is the only compound registered in the treatment of ALS, is not able to protect excitotoxic neurons by treatment with NMDA / Ser.
- any nucleic acid fragment including antisense RNA in order to inhibit the expression of calcineurin in patients suffering from such pathologies
- any chemical compound in particular the cyclosporine A or of compound FK506, or of any pharmaceutical composition containing them, with the aim of inhibiting the activity of calcineurin in patients suffering from such pathologies
