Scientists Uncover New Organelle Complexes in Human Cells: Hemifusomes

Quick Summary

• Researchers from the University of Virginia and NIH uncovered a new cellular organelle named hemifusome, constituting up to 10% of vesicular organelles at the cell periphery.
• Hemifusomes play a role in cellular sorting,recycling,debris disposal but do not participate in canonical endocytic pathways.
• cryo-electron tomography (cryo-ET) was used to create detailed images of hemifusomes.
• Scientists liken hemifusomes to “loading docks” where vesicles (“delivery trucks”) connect and transfer cargo within cells.
• functions of hemifusomes may impact diseases like Hermansky-Pudlak syndrome,a rare genetic disorder causing albinism,vision problems,lung disease,and blood clotting issues.
• Researchers aim to explore how these organelles contribute to both healthy cell function and disease mechanisms.
• The study could pave the way for targeted treatments for genetic disorders.
