UTILISAΗON A DES FINS DE DIAGNOSTIC ET THERAPEUΗQUES D'UN POLYPEPTIDE A ACTIVITE DE RECEPTEUR OB25 EXPRIME PAR LES CELLULES MYELINISANTESUSE FOR DIAGNOSIS AND THERAPEUTICS OF A POLYPEPTIDE HAVING OB25 RECEPTOR ACTIVITY EXPRESSED BY MYELINIZING CELLS
La présente invention a trait à l'utilisation à des fins de diagnostic et thérapeutiques d'un polypeptide ayant une activité de récepteur exprimé dans les cellules myelinisantes, dénommé récepteur OB25.The present invention relates to the use for diagnostic and therapeutic purposes of a polypeptide having a receptor activity expressed in myelinating cells, called the OB25 receptor.
Elle concerne ainsi l'utilisation de ce polypeptide pour le diagnostic d'affections neurologiques ou métaboliques affectant principalement les cellules produisant la myéline.It thus relates to the use of this polypeptide for the diagnosis of neurological or metabolic disorders mainly affecting the cells producing myelin.
L'invention est en particulier relative au diagnostic de maladies d'origine génétique impliquant les cellules productrices de myéline ou à la recherche de facteurs de susceptibilité à une telle maladie. L'invention concerne encore l'utilisation de ce polypeptide pour la mise au point de médicaments destinés au traitement des affections précitées.The invention relates in particular to the diagnosis of diseases of genetic origin involving myelin-producing cells or to the search for factors of susceptibility to such a disease. The invention also relates to the use of this polypeptide for the development of medicaments intended for the treatment of the abovementioned conditions.
Elle concerne aussi le traitement de maladies génétiques impliquant les cellules productrices de myéline.It also relates to the treatment of genetic diseases involving the cells producing myelin.
L'invention est encore relative à l'utilisation de sondes nucléotidiques susceptibles de se fixer par hybridation sur la séquence ou la séquence complémentaire, le transcrit ou les gènes codant pour ledit polypeptide et destinées au diagnostic et à la sélection de médicaments utilisables dans le traitement de maladies neurologiques ou métaboliques, notamment pour le traitement de maladies de la myéline, de maladies neuromusculaires.The invention also relates to the use of nucleotide probes capable of fixing by hybridization on the sequence or the complementary sequence, the transcript or the genes coding for said polypeptide and intended for the diagnosis and the selection of medicaments usable in the treatment neurological or metabolic diseases, especially for the treatment of myelin diseases, neuromuscular diseases.
L'invention a également trait à l'utilisation d'anticorps monocloπaux ou polyclonaux, dirigés contre ledit polypeptide, aux fins précitées.The invention also relates to the use of monoclonal or polyclonal antibodies, directed against said polypeptide, for the aforementioned purposes.
Elle concerne aussi des moyens de criblage de candidats médicaments pour le traitement desdites affections. Enfin, l'invention a trait à des médicaments destinés notamment au traitement d'affections neurologiques ou métaboliques affectant principalement les cellules productrices de la myéline, notamment la sclérose en plaques ou les gliomes, les maladies neuro-musculaires, contenant une substance ayant une affinité élevée pour ledit polypeptide à activité de 0 récepteur spécifique des cellules myelinisantes chez le rat ou encore des substances ayant une activité sur des cellules transfectées par une séquence codant pour ledit polypeptide.
Les maladies de la myéhnisation peuvent être acquises suite à une inflammation ou à une infection, être d'origine nutπtionnelle ou toxique, secondaires à une affection neuronale ou bien encore à déterminants génétiques Les voies de traitement connues à ce jour pour les maladies de la myéhnisation sont essentiellement symptomatiques (anti-inflammatoires)It also relates to means for screening drug candidates for the treatment of said conditions. Finally, the invention relates to medicaments intended in particular for the treatment of neurological or metabolic disorders mainly affecting myelin-producing cells, in particular multiple sclerosis or gliomas, neuro-muscular diseases, containing a substance having an affinity high for said polypeptide with 0 receptor activity specific for myelinating cells in rats or else substances having activity on cells transfected with a sequence coding for said polypeptide. The diseases of myéhnisation can be acquired following an inflammation or an infection, be of nutritional or toxic origin, secondary to a neuronal affection or even to genetic determinants The ways of treatment known to date for the diseases of myéhnisation are essentially symptomatic (anti-inflammatory)
Dans le traitement de ces maladies profondément handicapantes, l'un des objectifs est d'obtenir une stimulation de la synthèse et de la production de myéline ou bien la multiplication ou la différentiation des cellules produisant la myéline (oligodendrocytes et cellules de Schwann) La réalisation de cet objectif se heurte au fait qu'il n'existe que très peu de facteurs connus susceptibles de moduler spécifiquement l'activité des cellules productrices de myélineIn the treatment of these profoundly disabling diseases, one of the objectives is to obtain stimulation of the synthesis and production of myelin or else the multiplication or differentiation of the cells producing myelin (oligodendrocytes and Schwann cells). of this objective comes up against the fact that there are very few known factors capable of specifically modulating the activity of myelin-producing cells
Les gènes impliqués dans la synthèse, l'enroulement ou la compaction de la myéline constituent, à l'évidence, des gènes candidats dans les affections démyélimsantes pour lesquelles une composante génétique est évoquée ou avérée, et dont le locus reste à identifierThe genes involved in the synthesis, coiling or compaction of myelin constitute, obviously, candidate genes in demyelimiting conditions for which a genetic component is evoked or proven, and whose locus remains to be identified.
Il y a donc un intérêt pour le diagnostic et le traitement des maladies de la myéline, notamment des maladies neuromusculaires, à utiliser un récepteur exprimé par les cellules productrices de myéline et ses ligands naturels ou synthétiquesThere is therefore an interest in the diagnosis and treatment of myelin diseases, in particular neuromuscular diseases, in using a receptor expressed by myelin producing cells and its natural or synthetic ligands
La présente invention répond à ce besoin en fournissant des moyens utiles à des fins de diagnostics et de traitement des maladies de la myéhnisation Le polypeptide ayant une activité de récepteur OB25 utilisé selon l'invention est constitué par ou comprend tout ou partie de la séquence d'acides aminés de rat définie dans l'identificateur de séquence SEQ ID N° 2 ou une séquence homologue contenant le ou les sites faisant partie de ladite séquence peptidique dont la présence est nécessaire pour que le polypeptide ait les mêmes caractéristiques pharmacologiques que le récepteur OB25 ou pour qu'il soit reconnu par des anticorps qui reconnaissent également la séquence d'acides aminés précitée
Cette homologie peut être une homologie d'espèce ou une homologie correspondant à des mutations artificielles ou spontanées de nature ponctuelle et ne modifiant pas les propriétés essentielles du polypeptide et notamment son activité sur le récepteur OB25. Le polypeptide selon l'invention a été obtenu par criblage d'une banque d'ADN copie de bulbe olfactif de rat en utilisant des sondes nucléotidiques codant pour des récepteurs de la famille des récepteurs heptahélicaux couplés aux protéines G.The present invention meets this need by providing useful means for the purposes of diagnosis and treatment of myehnization diseases. The polypeptide having an OB25 receptor activity used according to the invention consists of or comprises all or part of the sequence d amino acid of rat defined in the sequence identifier SEQ ID No. 2 or a homologous sequence containing the site or sites forming part of said peptide sequence whose presence is necessary for the polypeptide to have the same pharmacological characteristics as the OB25 receptor or for it to be recognized by antibodies which also recognize the aforementioned amino acid sequence This homology may be a species homology or a homology corresponding to artificial or spontaneous mutations of a point nature and not modifying the essential properties of the polypeptide and in particular its activity on the OB25 receptor. The polypeptide according to the invention was obtained by screening a DNA library of rat olfactory bulb using nucleotide probes coding for receptors of the family of heptahelical receptors coupled to G proteins.
Le polypeptide selon l'invention peut être utilisé en étant isolé ou fixé sur des supports, d'une façon tout-à-fait classique, ou encore en étant associé à des séquences d'acides aminés sans relation avec le récepteur OB25.The polypeptide according to the invention can be used by being isolated or fixed on supports, in a completely conventional manner, or also by being associated with amino acid sequences unrelated to the OB25 receptor.
Ayant établi la séquence codante du récepteur OB25 (donnée dans la liste de séquences annexée), les inventeurs ont constaté que celle-ci est homologue (82,8% d'identité en nucleotides) à une séquence obtenue chez le mouton, apparaissant dans la base Genbank sous le code d'accès U 18405. Les informations accompagnant cette séquence n'indiquent qu'une structure compatible avec un couplage à une protéine G, mais aucune fonction ni utilisation pratique de cette séquence n'est suggérée. De même, I. Masana et coll. (Receptors and Channels, 1995, 3 :Having established the coding sequence of the OB25 receptor (given in the annexed sequence list), the inventors have found that it is homologous (82.8% nucleotide identity) to a sequence obtained in sheep, appearing in the Genbank database under access code U 18405. The information accompanying this sequence indicates only a structure compatible with coupling to a G protein, but no function or practical use of this sequence is suggested. Similarly, I. Masana et al. (Receptors and Channels, 1995, 3:
255-262) décrivent le clonage de l'ADNc de mouton correspondant à cette séquence et l'expression dans une cellule CHO dont le pouvoir de division en présence de sérum paraît accru. Cette réponse mitogène est commune à de nombreux récepteurs recombinants de la même superfamille et ne suggère en rien la fonction ni l'utilisation pratique du récepteur exprimé dans ce système artificiel.255-262) describe the cloning of sheep cDNA corresponding to this sequence and the expression in a CHO cell whose division power in the presence of serum appears to be increased. This mitogenic response is common to many recombinant receptors of the same superfamily and in no way suggests the function or practical use of the receptor expressed in this artificial system.
Cette séquence possède une homologie d'espèce avec les séquences répertoriées dans GENBANK sous les n° HSU78192, HSU8081 1 , BTU48236, MMU70622 et MMU48235. Une portion de la séquence codante du récepteur OB25 est également homologue (91 ; 1 % d'identité en nucleotides) à une séquence humaine (code d'accès à Genbank HSC1 CG081 ), obtenue par séquençage systématique d'ADN complémentaires (Expressed Séquence Tags), sans que

A portion of the OB25 receptor coding sequence is also homologous (91; 1% nucleotide identity) to a human sequence (Genbank access code HSC1 CG081), obtained by systematic sequencing of complementary DNA (Expressed Sequence Tags ), without the correspondence with a receptor fragment nor, a fortiori, that a function is not attributed to it
Une homologie a également été constatée avec les séquences humaines décrites dans les documents WO 96/39436 et WO 97/00952 De manière inattendue, les inventeurs ont établi que le récepteurHomology has also been observed with the human sequences described in documents WO 96/39436 and WO 97/00952 Unexpectedly, the inventors have established that the receptor
OB25 est exprimé dans les cellules productrices de myéline, à savoir les cellules de Schwann et les oligodendrocytes et que son expression au cours du développement est en accord avec un rôle dans la myéhnisationOB25 is expressed in myelin-producing cells, namely Schwann cells and oligodendrocytes and that its expression during development is consistent with a role in myehnization
Les inventeurs ont en particulier établi cette localisation du récepteur OB25 chez l'homme et chez le rat. L'existence et la localisation d'une telle expression du récepteur OB25 n'avaient jusqu'ici pas été déterminéesThe inventors have in particular established this localization of the OB25 receptor in humans and in rats. The existence and location of such an expression of the OB25 receptor had so far not been determined
