Annual Meeting

These walls are worth the cost

Biochemistry of lipids and membranes: 2020 annual meeting track

Are you the type of person who feels comforted by being within the walls of your living space? Similar to us in our homes, cells are separated from each other by lipid membranes that also encapsulate the various collection of organelles therein. However, lipid membranes are much more than simple barriers. Different membrane-bound structures have distinct lipid compositions that confer identity, are dynamic and adaptable, communicate extensively with one another through physical contact sites, and provide an energy-rich storage depot available when times are rough. Further, like the doors and windows in your house, membrane proteins provide a means by which the two sides demarcated by a lipid bilayer can communicate.

An exciting emerging principle is that specific lipids are required for the activity of many membrane proteins. The goal of this track is to showcase the multitude of hats worn by lipids in both health and disease.

Keywords: lipids, membrane dynamics, homeostatic mechanisms, lipid metabolism, membrane proteins.

Who should attend: anyone who feels underappreciated, because that is exactly how lipids and their researchers have felt for decades; people unafraid of grease — and those who are, too.

Theme song: “Insane in the Membrane” by Cypress Hill.

This track is powered by Vaseline.
