Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Cytokines can be produced within the nervous system by various cell types, including astrocytes, which secrete them in response to pathological processes such as viral infections. Astrocytes are known to play an important role in the homeostasis of the ner ...
Adenosine triphosphate (ATP) promotes glycogenolysis in primary cultures of mouse cerebral cortical astrocytes with an EC50 of 1.5 microM. A pharmacological analysis indicates an involvement of purinergic P2Y receptors in this action of ATP. Application of ...
We analyze a model of navigational map formation based on correlation-based, temporally asymmetric potentiation and depression of synapses between hippocampal place cells. We show that synaptic modification during random exploration of an environment shift ...
Evidence suggests that astrocytes might play an important role in cerebral energy metabolism. A recently developed cell line, called DI TNC1, displays several characteristic features of astrocytes. Thus, we have investigated in these cells a number of para ...
The cDNA for mouse brain glycogen synthase has been isolated by screening a mouse cerebral cortical astrocyte lambda ZAP II cDNA library. The mouse brain glycogen synthase cDNA is 3.5 kilobases in length and encodes a protein of 737 amino acids. The coding ...
The type beta transforming growth factors (TGF) are potent regulators of the growth and functions of lymphocytes and macrophages. Recently the human glioblastoma cell line 308 was shown to produce TGF-beta 2. The relevance of this finding was evaluated fur ...
Neurotransmitters are the molecules that neurons use to communicate with each other and with the other cell types of the nervous system, such as glial cells and cells of the vasculature. The best characterized actions of neurotransmitters are the alteratio ...
Because of the importance of neural recognition molecules expressed by glial cells to mediate interactions with neurons, growth factors and cytokines known to be functional during morphogenesis and in diseases of the nervous system were studied for their e ...
A growing number of biologically active peptides is being identified within the central nervous system (CNS). According to currently accepted criteria, several of these peptides, including VIP, can be viewed as neurotransmitters. Recent immunohistochemical ...
The transcription factors CCAAT/enhancer binding protein (C/EBP)-beta and -delta are key regulators for the expression of the acute phase genes in the liver, such as complement component C3 and antichymotrypsin. In the brain, these acute phase proteins are ...
