This article reviews the roles of various inflammatory cytokines in inflammatory diseases, focusing on interleukin (IL)-6, IL-1, IL-33, tumor necrosis factor-alpha (TNF-α), IL-10, and IL-8. It discusses their biological functions, signaling pathways, and their roles in conditions such as shock, trauma, immune dysregulation, osteoporosis, and critical illness. The article highlights the importance of these cytokines in both pro- and anti-inflammatory responses, their involvement in disease progression, and their potential as biomarkers or therapeutic targets. IL-6 is described as a key player in inflammation, with dual roles in promoting and suppressing inflammatory responses. It is involved in immune cell activation, tissue repair, and disease processes like cancer and osteoporosis. IL-1, a key cytokine in the innate immune response, is involved in inflammation, fever, and autoinflammatory diseases. IL-1β requires processing to become active, and its dysregulation is linked to conditions such as rheumatoid arthritis and atherosclerosis. IL-33, a member of the IL-1 family, is involved in type 2 immune responses and has roles in allergic and autoimmune diseases. TNF-α is a critical cytokine in inflammation, involved in immune cell activation, tissue damage, and disease progression, with therapeutic applications in autoimmune diseases. IL-10 is an anti-inflammatory cytokine that suppresses immune responses and is involved in regulating inflammation and bone metabolism. IL-8 is a chemokine that attracts neutrophils and is involved in inflammatory processes. The article emphasizes the complex roles of these cytokines in disease pathogenesis and their potential as therapeutic targets.This article reviews the roles of various inflammatory cytokines in inflammatory diseases, focusing on interleukin (IL)-6, IL-1, IL-33, tumor necrosis factor-alpha (TNF-α), IL-10, and IL-8.
