Cytokines: The Chemical Messengers of Immune Warfare
Cytokines — a diverse superfamily of small secreted proteins including interleukins, interferons, tumour necrosis factors, and chemokines — serve as the primary chemical communication network of the immune system, coordinating the activation, proliferation, differentiation, migration, and resolution of immune responses across both innate and adaptive immune compartments. The exquisitely balanced pro-inflammatory and anti-inflammatory cytokine networks that characterise a healthy immune response are systematically disrupted by environmental toxins: heavy metals including mercury and lead stimulate aberrant Th2-dominant responses; pesticides including organophosphates impair interferon-gamma production; lipopolysaccharide (LPS) from leaky gut triggers chronic low-grade TNF-alpha and IL-6 elevation; and EMF exposure has been shown to activate NF-kappaB — the master transcription factor governing inflammatory cytokine production. The resulting state of cytokine dysregulation — detectable as chronically elevated high-sensitivity CRP, IL-6, and TNF-alpha — is now recognised as the common thread linking virtually every chronic disease condition in the modern epidemic.
