Impact of common viruses on microglia and immune reactions.

Viruses	Impact of microglia	Immune responses
Z1KV	Viral reservoir for the transmission and dissemination	Innate and adaptive immune responses
	Production of type I and type IIIFNs, as well as neurotoxic factors
BVDV	Viral reservoir for the transmission and dissemination	Type 1 11Th response
	Intense type I IFN-stimulated protein ISG 15 expression
JEV	Viral reservoir for the transmission and dissemination	Innate and adaptive immune responses
	Production of inflammatory mediators
CMV	Viral reservoir for the transmission and dissemination	Innate and adaptive immune responses
	Increased cytokines and chemokines production
SARS-CoV-2	Viral reservoir?	Innate and adaptive immune responses
	Proinflammatory activation and M1 phenotype polarization
Influenza	Viral reservoir?	Innate and adaptive immune responses
	Increased expression of cytokines and chemokines
