Proinflammatory Cytokine Secretion (TNF-alpha-induced IL-8) (TNFα-induced IL-8 Secretion)

Target
TNFα-induced IL-8 Secretion
Molecular classification
Cytokine signaling pathway, Inflammatory pathway
01

Overview

Proinflammatory cytokine secretion, specifically the TNF-α-induced production and secretion of IL-8, is a key inflammatory pathway. TNF-α stimulates cells, leading to NF-kB and PI3K/Akt activation, resulting in increased IL-8 expression. IL-8, a chemokine, recruits neutrophils and other immune cells, amplifying inflammation. This process is implicated in various diseases, including autoimmune disorders and cytokine storms. Therapeutic strategies target TNF-α or downstream signaling molecules to reduce IL-8 production and its inflammatory effects.
