This review discusses 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. These cytokines are involved in the pathogenesis of inflammatory conditions such as shock, trauma, immune dysregulation, osteoporosis, and critical illness. They can act as biomarkers for disease monitoring and may serve as therapeutic targets. The review highlights the complex roles of these cytokines, including their pro- and anti-inflammatory effects, signaling pathways, and interactions with other immune components. IL-6 is essential for leukocyte switching and has roles in inflammation, tissue repair, and disease progression. IL-1 family members, including IL-1α and IL-1β, are key in inflammatory responses, with IL-1β being activated through proteolytic processing. IL-33 is involved in type 2 immune responses and has roles in allergic and autoimmune diseases. TNF-α is a critical cytokine in inflammation, contributing to cell survival, death, and immune responses. IL-10 is an anti-inflammatory cytokine that suppresses immune responses and has roles in regulating immune cell function. The review also discusses the clinical relevance of these cytokines in diseases such as osteoporosis, rheumatoid arthritis, and sepsis, highlighting their potential as biomarkers and therapeutic targets.This review discusses 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.
