Anti-inflammatory cytokines (AICs)

Anti-inflammatory cytokines Overview

Anti-inflammatory cytokines are a group of immunomodulatory molecules that play a critical role in controlling the pro-inflammatory response and maintaining immune homeostasis (NIH, 2021). Key members include Interleukin-10 (IL-10), Transforming Growth Factor-beta (TGF-beta), Interleukin-4 (IL-4), and Interleukin-1 receptor antagonist (IL-1Ra) (Sino Biological, 2023). These molecules act by inhibiting the production of pro-inflammatory cytokines or by antagonizing their signaling pathways (PubMed, 2010). In many inflammatory and autoimmune conditions, the balance between pro- and anti-inflammatory cytokines is disrupted, making the induction of anti-inflammatory cytokine gene expression a key therapeutic goal (ResearchGate, 2020). Drugs such as glucocorticoids and certain immunomodulators work by upregulating the expression of these cytokines to resolve inflammation (Frontiers, 2021). Conversely, some therapies utilize recombinant versions of these cytokines or their receptors to directly suppress immune activity (PMC, 2010). However, excessive anti-inflammatory activity can lead to profound immunosuppression and increased risk of infection (NIH, 2021). Additionally, certain cytokines like TGF-beta can have dual roles, promoting tissue repair in some contexts while facilitating tumor progression in others (Wikipedia, 2024).

Mechanism of Action

Agonism of anti-inflammatory pathways, induction of gene expression via transcription factors (e.g., STAT3, FoxP3), and inhibition of pro-inflammatory cytokine synthesis (PubMed, 2010; NIH, 2021).
