The paper shows filopodia can penetrate neighboring cells to form impact sites that initiate trans-endocytosis, with internalized tips often being double-membraned and associated with endoplasmic reticulum.

This study shows that Sac1 regulates Golgi V-ATPase assembly by controlling TGN membrane composition through lipid exchange, leading to Golgi fragmentation and impaired glycosylation.

This study identifies RRBP1 as a novel peroxisome biogenesis factor in human cells, showing it promotes peroxisome formation and stabilizes peroxisomal proteins.

This study shows how herpesvirus infection alters mitochondrial structure and metabolism during infection progression.

This study shows mitochondrial dysfunction in astrocytes disrupts primary ciliary homeostasis, linking mitochondrial stress to ciliary signaling and neurodegenerative disease mechanisms.

This study generates and benchmarks functionally mature stem cell-derived islets, showing they closely resemble primary adult islets in transcriptional and functional properties.
