Witryna19 sie 2024 · On the other hand, genetic loss of CX3CR1, a receptor primarily expressed by microglia in the brain, is also associated with synaptic pruning deficits, resulting in an excess of dendritic spines ... Witryna13 kwi 2024 · New scientific research performed in animal models with the deletion of PINK1 mice provided an indication that a lack of PINK1 results in impaired synaptic plasticity, which is caspase-mediated . Caspase-3 presents an additional role in neuronal processes, including the regulation of synaptic function and pruning [95,151,152]. WitrynaThe three models explaining synaptic pruning are axon degeneration, axon retraction, and axon shedding. In all cases, the synapses are formed by a transient axon terminal, and synapse elimination is caused by the axon pruning. Each model offers a different method in which the axon is removed to delete the synapse. ebony wedding dresses
