L’énergie est le principal facteur déterminant de la viabilité neuronale. Dans cette synthèse, nous proposons l’hypothèse d’une activation anormale de la glycolyse aérobie par la stimulation de la voie de signalisation canonique WNT/β-caténine dans la sclérose latérale amyotrophique (SLA). La stimulation de la voie canonique WNT induit en effet l’activation de la glycolyse aérobie, appelée aussi effet Warburg, via la stimulation des enzymes glycolytiques comme PKM2, PDK1, LDH-A et MCT-1 et les transporteurs de glucose Glut.

Epiretinal prostheses are designed to restore vision to people blinded by photoreceptor degenerative diseases by stimulating surviving retinal ganglion cells (RGCs), which carry visual signals to the brain.

Abstract:
Prolonged activation of skeletal muscle leads to a decline of force production known as fatigue. In this review we outline the ionic and metabolic changes that occur in muscle during prolonged activity and focus on how these changes might lead to reduced force. We discuss two distinct types of fatigue: fatigue due to continuous high-frequency stimulation and fatigue due to repeated tetanic stimulation. The causes of force decline are considered under three categories: 1) reduced Ca2+ release from the sarcoplasmic reticulum, 2) reduced myofibrillar Ca2+ sensitivity, and 3) reduced maximum Ca(2+

Abstract:
Natural killer (NK) cells are central components of the innate immunity. In murine models, it has been shown that NK cells can control both local tumor growth and metastasis due to their ability to exert direct cellular cytotoxicity without prior sensitization and to secrete immunostimulatory cytokines like IFN-γ. The latter participates in cancer elimination by inhibiting cellular proliferation and angiogenesis, promoting apoptosis, and stimulating the adaptive immune system, and it is instrumental for enhancing Ag processing and presentation. Nevertheless, NK cells display impaired functiona

1. In the lobster Palinurus vulgaris a sensory input in the lateral posterolateral nerve (lpln) of the stomatogastric nervous system (STS) is able to turn on the cardiac sac (CS) network and to induce dramatic long-lasting alterations in the output of the pyloric network. This long-lasting alteration of pyloric network output consists primarily of changes in the activity of the two neurons that innervate the muscles of the cardiopyloric valve of the stomach, with the dilator neuron (the ventricular dilator, VD) transferring from the pyloric network to the CS network and the constrictor neuron

Abstract:
With the use of intracellular techniques and a medullary slice preparation, we examined the changes in cellular and membrane properties of single adult rat vagal motoneurons during exposure to potent and specific agonists and antagonists of adenosine A1 and A2 receptors. A1 receptor stimulation increased input resistance, but markedly reduced spontaneous neuronal firing and increased rheobase. A1 agonists also increased the amplitude of the action potential afterhyperpolarization (AHP) in a dose-dependent manner. Prior treatment with A1 antagonists blocked these electrophysiological effects. B

The combination of the stimulating and inhibiting amino acids - Leucine with Proline or Tyrosine-, lead to the proliferation stimulation by 24-32%.

Abstract Induction of potent and sustained antiviral or antitumor immunity is dependent on the efficient activation of CD8+ and CD4+ T cells. While dendritic cells constitute a powerful platform for stimulating cellular immunity, presentation of endogenous antigens by dendritic cells transfected with nucleic acid-encoded antigens favors the stimulation of CD8+ T cells over that of CD4+ T cells. A short incubation of mRNA-transfected dendritic cells with antisense oligonucleotides directed against the invariant chain enhances the presentation of mRNA-encoded class II epitopes and activation of
