TLR4 participates in the transmission of ethanol-induced neuroinflammation via astrocyte-derived extracellular vesicles

2019

Background Current evidence indicates that extracellular vesicles (EVs) participate in intercellular signaling, and in the regulation and amplification of neuroinflammation. We have previously shown that ethanol activates glial cells through Toll-like receptor 4 (TLR4) by triggering neuroinflammation. Here, we evaluate if ethanol and the TLR4 response change the release and inflammatory content of astrocyte-derived EVs, and whether these vesicles are capable of communicating with neurons by spreading neuroinflammation. Methods Cortical neurons and astrocytes in culture were used. EVs were isolated from the extracellular medium of the primary culture of the WT and TLR4-KO astrocytes treated …

Exosomes as mediators of neuron-glia communication in neuroinflammation

2019

In recent years, a type of extracellular vesicles named exosomes has emerged that play an important role in intercellular communication under physiological and pathological conditions. These nanovesicles (30–150 nm) contain proteins, RNAs and lipids, and their internalization by bystander cells could alter their normal functions. This review focuses on recent knowledge about exosomes as messengers of neuron-glia communication and their participation in the physiological and pathological functions in the central nervous system. Special emphasis is placed on the role of exosomes under toxic or pathological stimuli within the brain, in which the glial exosomes containing inflammatory molecules…

The absence of the calnexin expression in the exosome samples confirmed the absence of cytosolic protein contamination. A sample of astrocyte lysate was used as positive control of the calnexin expression. (TIF 489 kb)
