General description

Methyl-β-cyclodextrin is a small cyclic heptasaccharide.

Application

Methyl-β-cyclodextrin has been used as a cholesterol chelator:
  • to study its effects on mice cardiomyocytes
  • to study its effects on human corneal stromal fibroblasts
  • to study its effects on the junctophilin-2 (JPH2) pool

Biochem/physiol Actions

Methyl-β-cyclodextrin participates in increasing the permeability of cells. It also plays a role in depolymerizing the actin cytoskeleton in cells. Methyl-β-cyclodextrin is involved in attracting cholesterol from the plasma. It participates in activating extracellular receptor kinase in certain cells.

Methyl-beta-cyclodextrin and filipin are cholesterol-binding reagents often used interchangeably to investigate functional requirements for lipid rafts in receptor-mediated signal transduction. Recently, contradictory results were reported by two groups using these reagents in different model systems to investigate the role of
