  • At present I am investigating, together with my collaborators, the interactions which occur among the membranes of the various compartments of the secertory pathway, namely the endoplasmic reticulum, the Golgi complex, the secretion granules, and the plasmalemma.

  • Another scenario to explain the remarkable effect of CD on cholesterol and GSL storage in neurons, but not requiring direct access to the E/L system, would be an interaction with cholesterol at the neuronal plasmalemma.

  • CD could also extract cholesterol from the plasmalemma of endothelial cells lining the BBB and either shuttle cholesterol to acceptor molecules or act as a sink within the bloodstream as discussed earlier.

  • If CD does enter the brain, it presumably could exert its impact on cholesterol and GSL accumulation by acting at the plasmalemma of brain cells or after being internalized.
