Cytokine Signaling Pathway (including TNF-alpha)

The cytokine signaling pathway is a complex network of intercellular communication mediated by small secreted proteins called cytokines. This pathway regulates diverse cellular processes, including immunity, inflammation, and hematopoiesis. TNF-alpha is a key pro-inflammatory cytokine within this network, acting through receptors such as TNFR1 and TNFR2 to activate downstream signaling cascades that impact cell survival, apoptosis, and inflammatory gene expression. Dysregulation of cytokine signaling is implicated in various diseases, including autoimmune disorders, chronic inflammatory conditions, and cancer.

Varies depending on the specific drug and target within the pathway. Examples include: receptor blockade (e.g., TNF-alpha inhibitors), inhibition of intracellular signaling kinases (e.g., JAK inhibitors), and modulation of gene transcription (e.g., corticosteroids).
