In this review, we discuss the state of current knowledge regarding the molecular mechanisms and types of genetic mutations that lead to cystic fibrosis and highlight recent developments in gene therapy that can be leveraged to correct these mutations and to restore the physiological function of the carrier protein transporting sodium and chlorine ions in the airway epithelial cells. Restoration of carrier protein expression could lead to the normalization of ion and water transport across the membrane and induce a decrease in the viscosity of airway surface fluid, which is one of the pathological manifestations of this disease.

The BOLD signal is only indirectly related to the underlying neuronal activity; therefore, it remains an open question whether connectivity and changes in it are only manifestations of normal and pathological states of the brain or they are, to some extent, the causes of these states. The creation of chemogenetic receptors activated by synthetic drugs (designer receptors exclusively activated by designer drugs, DREADDs), which, depending on the receptor type, either facilitate or, on the contrary, inhibit the neuronal response to received physiological stimuli, makes it possible to assess brain connectivity in the light of controlled neuronal activity. Evidence suggests that connectivity is based on neuronal activity and is a manifestation of connections between brain regions that integrate sensory, cognitive, and motor functions. Chemogenetic modulation of the activity of various groups and types of neurons changes the connectivity of the brain and its complex functions. Chemogenetics can be useful in reconfiguring the pathological mechanisms of nervous and mental diseases. The initiated integration, based on the whole-brain connectome from molecular-cellular, neuronal, and synaptic processes to higher nervous activity and behavior, has the potential to significantly increase the fundamental and applied value of this branch of neuroscience.</p>","PeriodicalId":6989,"journal":{"name":"Acta Naturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10395778/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10295678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La conception du dispositif, baptisée « Communauté-Population-Sol » (CPS) est novatrice et intègre trois composantes-clés de l’écosystème : la communauté végétale, la population végétale dominante et le sol, via des relevés exhaustifs de végétation vasculaire, des caractérisations de traits biologiques de la population végétale dominante (Molinia caerulea (L.)

C’est particulièrement vrai dans le bassin versant de la Garonne où plusieurs espèces sont répertoriées, mais avec beaucoup d’incertitude sur leur répartition et leur taxonomie. Un caractère particulier a été découvert chez certains chabots de ce bassin : ils ont trois rayons aux nageoires pelviennes, contre quatre rayons chez toutes les espèces européennes décrites aujourd’hui. Cet article étudie la répartition et l’écologie des Chabots de ce morphotype pour les comparer à celles des chabots du morphotype habituel à quatre rayons aux nageoires pelviennes. Les Chabots à trois rayons occupent essentiellement des rivières de basse altitude en terrain karstique. Leurs populations peuvent être réunies en un seul ensemble par l’aval du bassin-versant, ce qui suggère une origine géographique unique. Ceux à quatre rayons ne semblent pas inféodés à un habitat particulier et se trouvent fréquemment sur terrain cristallin ou magmatique dans des rivières prenant naissance en altitude. Ces différences biogéographiques et écologiques suggèrent que le caractère « trois rayons aux nageoires pelviennes » est un caractère permettant de définir une lignée phylogénétique particulière, possible nouvelle espèce. Des études morphologiques et génétiques sont nécessaires pour vérifier cette hypothèse. Si le Chabot à trois rayons est bien une nouvelle espèce, elle nécessiterait alors des niveaux de protection spécifiques compte tenu de ses faibles effectifs, du fractionnement de ses populations et des menaces auxquelles elle est confrontée.","PeriodicalId":6989,"journal":{"name":"Acta Naturae","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73163314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
