Robust analytical methods for bis(monoacylglycero)phosphate profiling in health and disease

Wentao Dong, Kwamina Nyame, Eshaan S. Rawat, Uche N. Medoh, Jian Xiong, Caio C. Bonin, Hisham N. Alsohybe, H LIU, Sara Gomes, Tammy Shalit, Marianna Arnold, F. Hsieh, Esther M. Sammler, Monther Abu-Remaileh

This study develops LC/MS methods for accurate BMP profiling, using CLN5 knockout cells to distinguish BMP from PG and introduce BMPII and BMPES metrics.

Extracellular vesicle-mediated release of bis(monoacylglycerol)phosphate is regulated by LRRK2 and Glucocerebrosidase activity

Elsa Meneses‐Salas, Moisés Castellá, Marianna Arnold, F. Hsieh, Ruben Fernandez-Santiago, Mario Ezquerra, Alícia Garrido, Marı́a José Martı́, Carlos Enrich, Suzanne R. Pfeffer, Kalpana Merchant, Albert Lu

This study shows that LRRK2 and GCase regulate BMP release via EVs, with mutant LRRK2 increasing EV-associated BMP and GCase modulating this effect.
