Intracellular Signaling

Intracellular signaling is essential for development, differentiation, survival and plasticity. G Proteins, Cyclic Nucleotides, Calcium, Phosphoinositides, Phosphorylation of different amino acids and Transcription Factors, are the main ways by which cells establish intracellular signaling in the nervous system. In this section you will find information about how these pathways are affected in different neuropaediatric disorders.

New roles of microglia in brain pathophysiology

Microglia cells represent, depending on the species, from 5% to 20% of the glial cells in the adult brain. It is commonly accepted that microglia precursors originate in the yolk sac – as the tissue specific macrophages – although their identity has not been confirmed so far. Once the development of the blood-brain barrier is […]

The diseases of the synaptic vesicles open the way to a new group of neurometabolic diseases

The Inborn Errors of Metabolism (IEM) have normally been considered as the result of errors at the genetic level affecting the biochemical pathways of small molecules such as the neurotransmitters glycine, glutamate, GABA, biogenic amines, etc. The altered concentration of such molecules in the Cerebrospinal Fluid (CSF) have always been used as a diagnostic biomarker […]

Microtubule transport system: a highway between neuronal cell body and synapses

Neuronal cells have developed a characteristic shape, which causes that the distance between the cell body and the synapses is often very long. Therefore, they have a complex and efficient system to transport many proteins from the center to the periphery, and vice versa. The process of transport of proteins from the cell body to […]

The lysosome signalization function: new mechanisms of neurological diseases

The role and the fame of the lysosomes in cell metabolism are mainly connected to their well-known activity of “garbage collectors”. They are plenty of hydrolytic enzymes that degrade different types of useless macromolecules, thus generating smaller, simpler basic molecules that can enter once again in the flow of the biochemical pathways of the cells. […]

Disruption of active zone affects synaptic vesicles only partially

The active zones are specific sites of presynaptic terminals where the docking and the release of synaptic vesicles occur. They are complex, organized protein structures that anchor synaptic vesicles to the plasma membrane. Once bound to the active zone and docked to the plasma membrane, synaptic vesicles can properly respond to the changes of action […]
