Expression of choline acetyltransferase, 200-kDa neurofilament protein, 28-kDa calbindin, neuronal NO synthase, caspase 3, and Ki-67 in the motor neurons of spinal cord segments T3-T5 in male C57Bl/6 mice after 30-day space flight in the Bion-M1 biosatellite was studied by immunohistochemical methods. Under conditions space flight, the size of motoneurons increased, the number of neurons containing choline acetyltransferase and neurofilaments, decreased, and the number of calbindin-positive neurons increased; motoneurons, expressing neuronal NO synthase and caspase 3 appeared, while Ki-67 was not detected. Fragmentation of neurons with the formation structures similar to apoptotic (residual) bodies was observed in individual caspase 3-positive motoneurons.
