Membrane turnover & maturation
How does a cell remove membranes without destroying its own compartments?
01 / The Central Question
Building membranes is only one part of keeping a cell healthy. Old or damaged material must also be enclosed, delivered to the right compartment and broken down safely.
If cells cannot break down unwanted membranes and damaged components, these materials may accumulate. This is relevant to understanding cellular changes associated with ageing and diseases involving impaired cellular recycling.
