FETUB and Alzheimer disease: Among acute phase proteins, the CSF of iNPH patients showed the highest levels of fetuin-B (FETUB), complement component C8 beta chain (C8B), complement component C9, Ig mu chain C region (IGHM), immunoglobulin heavy variable 5-51 (IGHV5-51) and immunoglobulin heavy variable 3-74 (IGHV3-74), whereas scavenger receptor cysteine-rich type 1 protein M130 (CD136) is higher in AD than in iNPH.
