Fusion of microglial cell to mature neuron stimulated by injection of retrovirus. 1, Stereotaxic injection of retrovirus into the forebrain infects microglia and stimulates their activation (2). 3, Activated microglial cell migrates and recognizes apical dendrite of a mature cortical pyramidal cell where it fuses, filling the cell with GFP (4). 5, Entire cytoplasm of the neuron is filled with GFP.
