A new organelle has been discovered in human cells — and scientists call it a “hemifusome.” Their function involved in sorting, recycling and discarding proteins within human cells. Hemifusomes may play a crucial role in the recycling or disposal of cellular membranes, which is important for preventing the buildup of stuff in cells that could gum up their operations if allowed to accumulate. The researchers wrote that understanding more about how hemifusomes work could also unlock new insight into how diseases such as Alzheimer’s manifest. Alzheimer’s disease is linked to the improper clearance of abnormal protein plaques in the brain, which leads to buildup over time.
