Phosphatidylserine turns the gears of phospholipids in B cell lymphoma

J Cell Biol. 2024 Feb 5;223(2):e202401047. doi: 10.1083/jcb.202401047. Epub 2024 Jan 25.

Abstract

Phosphatidylserine levels and distribution are tightly controlled by dedicated enzymes at the ER and plasma membrane. Nakatsu and Kawasaki discuss new work by Aoki and colleagues (https://doi.org/10.1083/jcb.202212074), which reveals an acute reliance on phosphatidylserine synthesis in B cell lymphomas needed to prevent aberrant B cell receptor activation and ensuing apoptosis.
