Vesicular stomatitis virus (VSV) infection of mice via intranasal administration results in a severe encephalitis with rapid activation and proliferation of microglia and astrocytes. We have recently shown that these glial cells express RIG-I and MDA5, cytosolic pattern recognition receptors for viral RNA. However, it is unclear whether VSV can replicate in glial cells or if such replication is required...
We have recently demonstrated that microglia and astrocytes express nucleotide-binding oligomerization domain-2 (NOD2), a novel cytosolic pattern recognition receptor for bacterial motifs, and we have shown that this intracellular receptor is essential for glial responses to Gram-negative pathogens. Here, we demonstrate that intact Staphylococcus aureus, a major Gram-positive causative agent of brain...
It is now widely accepted that resident central nervous system (CNS) cells such as microglia and astrocytes initiate and/or augment inflammation following trauma or infection. However, the mechanisms by which glial cells perceive microbial challenges are only now becoming apparent. We have recently demonstrated that microglia and astrocytes constitutively express nucleotide‐binding oligomerization...
Vesicular stomatitis virus (VSV) is a negative-sense single-stranded RNA virus that closely resembles its deadly cousin, rabies virus. In mice, VSV elicits a rapid and severe T cell—independent encephalitis, indicating that resident glial cells play an important role in the initiation of central nervous system (CNS) inflammation. Recently, retinoic acid—inducible gene I (RIG-I)-like helicases have...
