This suggests that membrane fluidity is […]

Yamaga et al. report that removing a protein called PLC, that metabolises a signalling lipid, increases exocytosis [1]. In other words, the substrate for PLC increases exocytosis. The substrate is an old friend of this blog, PIP2. […]

Some very recent research provides evidence that sphingolipids have a role in the physical process of division in at least one type of mammalian cell [5]. This physical role of this class of lipids is an unexpected contrast to the biological role sphingolipids have as molecular messengers in processes such as angiogenesis, neurodegeneration and diabetes. However it may not be unique; it appears that inositide lipids have both structural and biological roles. […]
