IL6 and infectious disease: Additionally, 102 (~29%) are soluble targets (e.g., TNF [tumor necrosis factor-alpha, TNF-α], IL6 [interleukin-6, IL-6], VEGFA [vascular endothelial growth factor A]), and 15 (~4.3%) are infectious disease targets (e.g., respiratory syncytial virus [RSV]-F protein, Bacillus anthracis protective antigen [PA] toxin component, influenza hemagglutinin 2 [HA2; stalk portion], human immunodeficiency virus [HIV] envelop protein gp120) (Table 5).
