Cell-to-cell signaling in brain
Research summary
The main goal of the laboratory is to characterize mechanisms of intercellular communication between glial cells and neurons. Recently we focused our attention on an unconventional secretory mechanism which is based on release of extracellular membrane microvesicles (EMVs) into the pericellular space. Through this process, microglial cells heavily influence brain cell functions, either propagating inflammation and causing damage to neurons or playing a supportive, neuroprotective role.
In vivo, microglia produce EMVs which reach the cerebrospinal fluid, where they are emerging as biomarkers of neuroinflammatory diseases. Indeed EMV production reflects the extent of microglial activation, and quantification of EMVs provides useful clinical information to capture disease activity in patients with neuroinflammatory and neurodegenerative brain disorders (Verderio et al., 2012; Joshi et al., 2014).
