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 […]

Anti-inflammatory drugs can reverse synaptic defects

Inflammation modifies risk and/or severity of a variety of brain diseases through still elusive molecular mechanisms. Tomasoni et al. (open access article available at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5370184/) show that hyperactivation of the interleukin 1 pathway, through either removal of the interleukin 1 receptor 8 (IL-1R8,) or activation of IL-1R, leads to up-regulation of the mTOR pathway and […]

The dynamic functional connectivity of the brain and the fMRI: an overview of analytical strategies

Resting-state functional magnetic resonance imaging (fMRI) is a method of functional brain imaging (i.e., the measurement of the aspect of a brain area by images) that can be used to evaluate regional interactions that occur when a subject is resting. The fMRI has highlighted the rich structure of brain activity in absence of a task or stimulus. […]

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 […]
