It is known that inflammatory stimuli, such as IFNs, lysophosphatidic acid (LPA), interleukins, TNF, and ligands of TLR, which are induced during viral infection, change miRNA expression in ECs, including miRNA-126, which is involved in the inflammatory response, angiogenesis, and vascular integrity [[17], [18], [19], [20],[44], [45], [46]]. The gene discussed is TNF; the disease is viral infectious disease.
