The Claim
Cholesterol depletion by methyl-β-cyclodextrin increases membrane tension and rupture susceptibility independently of the actomyosin cytoskeleton, as pharmacological disruption of actin filaments with cytochalasin D does not attenuate these mechanical effects.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Removing cholesterol from cell membranes using methyl-β-cyclodextrin makes membranes more likely to rupture and increases their tension, and this effect occurs even when the internal actin filaments are chemically disabled.
See the scientific wording
The mechanical effects of cholesterol depletion by methyl-β-cyclodextrin on membrane tension and rupture susceptibility are not mediated by the actomyosin cytoskeleton, as demonstrated by persistent increases in rupture propensity and tension even after pharmacological disruption of actin filaments with cytochalasin D.
Removing cholesterol from the cell membrane makes it stiffer and less able to stretch, so it tears more easily when pulled or pressed. This happens because cholesterol normally helps pack the membrane molecules tightly together; without it, the membrane becomes uneven and under more internal stress, making it break under pressure even if the cell's internal skeleton is broken.
What the research says
1 studyStudy: Cholesterol Depletion by MβCD Enhances Cell Membrane Tension and Its Variations-Reducing Integrity
Even when scientists break down the cell’s internal skeleton, removing cholesterol still makes the cell membrane more likely to pop under pressure—proving cholesterol strengthens the membrane on its own, not by relying on the cell’s internal structure.
