They are associated with many vital functionsincluding directing the innate immune response in mammalian systemsand have been implicated in various pathologies ranging from neurodegenerativediseases to viral infections.7−9 Interleukin 6 (IL-6) is a proinflammatorycytokine that can be produced by virtually every nucleated cell type.During inflammation, it is produced along with other proinflammatorycytokines such as interleukin-1β (IL-1β), IL-4, IL-10,macrophage chemoattractant protein-1 (MCP-1), and tumor necrosis factor-α(TNF-α). Here, IL6 is linked to viral infectious disease.
