Three altered bio-systems in CFS

Oxidative Stress Genes


Prostaglandin Synthase: COX-1 and 2, haemoglobin gamma A and gamma G



Apoptosis Genes: Up-regulated

Annexin -A3, -A5, Serine/threonine kinase 17b, Histones 1&2, Protein S (alpha), Serum deprivation response (Phosphatidylserine binding protein)

Caspase 1, TGFβ1

Death effector filament forming CED4-like apoptosis protein, Complement 3a receptor 1, Early growth response 1, TNF-A1P3, -RSF17, -SF4

Immune Dysfunction Genes (including markers of viral immuno-modulation/evasion)


DAF (CD55) & CD46

Antigen processing via MHC class II (MHC II DP α1 and DR α)

IL-12, IL-13 & IL-6 biosynthesis

Down-regulated: The MHC-1 system including:

Natural Killer cell receptors (KIR)

TCR complex (T-cell receptors α, β, δ, γ)

NO production (up-regulation of arginase I & II)

Flavohaemoprotein B5

Leukocyte-derived arginine aminopeptidase (L-rap)
