9/3/2023 0 Comments How many neurons in brainIf that long, thin projection ever seems like it could be vulnerable, a new MIT study shows that its structural integrity may indeed require the support of a surrounding protein called perlecan. Perhaps the most obvious feature of a neuron is the long branch called an axon that ventures far from the cell body to connect with other neurons or muscles. The study revealed that, without perlecan, the axons (long projections of neurons used for connection) can break apart during development, leading to the death of synapses (neuronal connections). Perlecan is part of the extracellular matrix that surrounds cells and helps them develop in a supportive, yet non-rigid environment. In a study conducted by MIT’s Picower Institute for Learning and Memory, researchers found that a protein named perlecan plays a crucial role in maintaining the structural integrity of neurons. Scientists find a protein common to flies and people is essential for supporting the structure of axons that neurons project to make circuit connections. Without it, axons can break, leading to the death of synapses. MIT scientists found that the protein perlecan, found in both flies and humans, is vital for maintaining the structural integrity of neuronal axons.
