Figure 4From: Reduced sphingosine kinase-1 and enhanced sphingosine 1-phosphate lyase expression demonstrate deregulated sphingosine 1-phosphate signaling in Alzheimer’s disease Correlation between neurons with strong expression of SPL and Aβ deposits. (a) Packing density of SPL++ neurons and density of Aβ deposits are not correlated in frontal cortex. (b) A positive correlation between the packing density of SPL++ neurons and the density of Aβ deposits is observed in entorhinal cortex. Data are represented as scatter plot with regression line.Back to article page
