The path to scientific discovery is rarely linear. For Monther Abu-Remaileh, his journey from a challenging high school experience in East Jerusalem to becoming a leading researcher in lysosomal biology at Stanford University is a testament to resilience, mentorship, and a relentless pursuit of understanding the fundamental mechanisms of disease. His work, poised to receive the American Society for Biochemistry and Molecular Biology’s 2026 Walter A. Shaw Young Investigator Award in Lipid Research, is shedding new light on neurodegenerative disorders like Alzheimer’s disease and offering potential avenues for future therapies.
Abu-Remaileh’s early education was significantly disrupted by the Second Intifada, a period of heightened conflict between Israelis and Palestinians. Attending school during this time meant navigating frequent closures and lengthy delays at military checkpoints for teachers. Despite these obstacles, the dedication of educators like physics teacher Yousef Alhroush, who went to extraordinary lengths to reach his students, kept Abu-Remaileh’s academic aspirations alive. Alhroush would travel through mountainous regions to avoid checkpoints and even slept in his classroom during the week to provide consistent instruction.
“Seeing all of that, even 25 years after, and probably 100 years after, it’s stuck in my brain,” Abu-Remaileh recalled. “What we have is what they did for you; you need to help your students as well.” This sense of obligation to mentor and support the next generation now defines his approach as a professor at Stanford University.
Abu-Remaileh’s academic success led him to the Jordan University of Science and Technology on scholarship, followed by graduate studies at the Hebrew University of Jerusalem. He then pursued postdoctoral training at the Whitehead Institute at MIT before establishing his own laboratory at Stanford, where he focuses on lysosomal lipid biochemistry. His research centers on understanding how disruptions in lysosome function contribute to the development of neurodegenerative diseases.
The Lysosome: From Recycling Center to Molecular Creation Site
For years, the lysosome has been understood as the cell’s primary recycling center, breaking down waste materials and cellular debris. However, Abu-Remaileh’s lab is redefining this understanding, revealing the lysosome as a dynamic organelle involved in the creation of essential molecules. This shift in perspective stems from their investigation into rare genetic disorders with unclear biological mechanisms. By systematically “knocking out” genes and using mass spectrometry to analyze changes in lipids, metabolites, and proteins, the team uncovered striking shifts in lysosomal lipids linked to neurodegeneration.
A key focus of their research is the ceroid-lipofuscinosis neuronal 5 gene, or CLN5. Mutations in this gene cause a severe childhood neurodegenerative disorder, and variations have also been linked to an increased risk of Alzheimer’s disease. The lab discovered that CLN5 produces bis(monoacylglycero)phosphate (BMP), a phospholipid crucial for lysosome metabolism. This finding fundamentally alters our understanding of the lysosome’s role within the cell.
Identifying a Potential Drug Target: PLA2G15
Building on their discovery of BMP’s importance, Abu-Remaileh’s team identified phospholipase A2 group XV (PLA2G15) as an enzyme responsible for degrading BMP. Remarkably, when they “knocked out” the PLA2G15 gene in a mouse model, BMP levels increased, and the severe neurodegeneration was reversed. This breakthrough, recently published in Nature, positions PLA2G15 as a promising target for the development of new drugs to treat lysosome-related diseases.
Abu-Remaileh will present these findings at the American Society for Biochemistry and Molecular Biology (ASBMB) 2026 Annual Meeting, further disseminating this critical research to the scientific community.
A Commitment to Diversity and Mentorship
Abu-Remaileh’s personal experiences have profoundly shaped his commitment to mentorship and fostering diversity in science. Having grown up in an East Jerusalem refugee camp and navigating political instability as a teenager, he understands the barriers faced by students from underrepresented backgrounds. He actively champions the importance of diversifying faculty and creating inclusive environments where all students have the opportunity to thrive.
“It’s crucial to diversify our faculty… because we have different perspectives,” he said. “We see different types of people, and that these people also have potential.”
Looking ahead, Abu-Remaileh’s lab will continue to investigate the intricate interplay between lysosomal lipid metabolism and neurodegenerative diseases, seeking to translate these fundamental discoveries into effective therapies. His story serves as an inspiring example of how overcoming adversity, coupled with dedicated mentorship and groundbreaking research, can unlock the secrets to improving human health.
