Discovery of the day
This study identifies the ceramide transfer protein (CERT) as a critical regulator of G-protein–coupled phospholipase C (PLC) signalling in Drosophila photoreceptors, demonstrating a novel in vivo function for non-vesicular lipid transfer at membrane contact sites. Researchers found that loss of the dcert gene alters ceramide metabolism and reduces the rate of PIP2 resynthesis after light-induced PLC stimulation, linking these defects to a decrease in ER-plasma membrane contact site density and the function of the MCS-localized protein RDGB. These findings highlight how intracellular lipid homeostasis and membrane architecture directly influence signal transduction cascades, offering a mechanistic framework that could inform your research on how cellular disruptions—potentially including those influencing fertility and aging—alter tissue function and organismal health.
