[Tunneling nanotubes (TNTs): An essential yet overlooked modality of inter-cellular communication].

Abstract

Tunneling nanotubes (TNTs) are open membranous protrusions that allow direct communication between distant cells. Recent research has revealed their significant biological roles, prompting a reassessment of many physiological and pathological processes, especially in the nervous system where TNT properties could play a key physiological role. TNT-like connections have been observed in the developing brain and are implicated in neurodegenerative diseases, brain cancers, as well as in other diseases, underscoring their importance in pathophysiological events.This review covers the key features of TNTs, including their structural properties, formation mechanisms, and detection challenges. We also explore their functions, focusing on the nervous system. The discovery of TNTs may lead to a reconsideration of brain function as a physically connected neuronal network, as proposed by Golgi, complementing Cajal’s theory of neurons as separate entities.

Les tunneling nanotubes (TNT) sont des protrusions membranaires ouvertes permettant la communication directe entre cellules distantes. Des recherches récentes ont révélé leur importance biologique, notamment dans le système nerveux où leurs rôles pourraient être cruciaux. Observés dans le cerveau en développement, les TNT sont impliqués dans les maladies neurodégénératives, les cancers du cerveau et dans d’autres types de maladies, soulignant leur rôle physiopathologique. Leur découverte pourrait conduire à reconsidérer le cerveau comme un réseau neuronal physiquement connecté, complémentant ainsi la théorie de Cajal1 sur les neurones en tant qu’entités distinctes.
