Interaction Information:

Comment S1P/sphingosine ratio was 2.5-fold higher in hippocampus of ApoE2 carriers compared to ApoE4 carriers, and multivariate regression showed a significant association between APOE genotype and hippocampal S1P/sphingosine (p‚ÄČ=‚ÄČ0.0495), suggesting a new link between APOE genotype and pre-disposition to AD.
