Recent cell biological studies suggest that sphingolipids and cholesterol may cluster in
biomembranes to form raft-like microdomains. Such lipid domains are postulated to function …

Unesterified (free) cholesterol is essential for cell viability with a critical function being the
maintenance of appropriate membrane structure (for reviews, see Refs. 1-3). Cells can …
