MFSD2A and Alzheimer disease: Recently, MFSD2a was identified as a transporter for DHA uptake from blood into the brain, and MFSD2a deficient mice showed decreased DHA levels in the brain [49]; knockout mice of MFSD2a might give us clues to the in vivo effects of DHA on the pathophysiology of AD, especially the effect of DHA deficiency on the amyloid pathology.
