IL1B and Creutzfeldt Jacob disease: Aside from the prion protein-related hypothesis, it is suggested that the cytokine profile in CJD can be pro-inflammatory and anti-inflammatory, with increases seen in the inflammatory cytokine interleukin 8 (IL8) and a decrease in transforming growth factor beta 2 (TGFB2) but no changes in the levels of interleukin 1 beta (IL1B), interleukin 12 (IL12), or tumor necrosis factor alpha (TNFA) [327].
