Figure 2 (panel hepatitis) shows that four cytokines have baseline levels associated with the future development of hepatitis; MIP-1α, (ME 0.18, SD 0.12), TNF-α (ME 0.45, SD 0.11), Interferon gamma-induced protein 10 (IP-10) (ME 0.64, SD 0.14) and cutaneous T cell-attracting chemokine (CTACK) (ME -0.21, SD 0.07). Here, TNF is linked to hepatitis A virus infection.
