MiR-155 is upregulated after cerebral ischemia and was identified and characterized as a component of microglia response to different types of inflammatory mediators, such as LPS, interferon- beta (IFN-β) and TNF-α and can be down-regulated by RSV (Cardoso et al., 2012 ▶). Here, IFNB1 is linked to Cerebral ischemia.
