Indeed, APOEε3/APOEε3 patients were observed to have significantly higher levels of FABP7 than APOEε4/APOEε4 patients, providing a novel connection between ApoE ε4 and FABP7 and suggesting that inhibition of FABP7 signaling may be one mechanism of ApoE ε4-induced AD development and/or progression. Here, APOE is linked to Alzheimer disease.
