Reorganization of actin cytoskeleton of nuclear erythrocytes and leukocytes in fish, frogs, and birds during migration

Using the method of confocal laser scanning microscopy, changes in the spatial organization of actin filaments of nuclear erythrocytes and leukocytes in fish, frogs, and birds during migration were studied. It has been shown that, during movement, in erythrocytes, like in leukocytes, reorganization of cytoskeleton microfilaments occurs. In the course of migration, in amphibians and birds, red blood cells form pseudopodia filled with bundles of actin filaments arranged in parallel, whereas no pseudopodia are formed in fish erythrocytes. The change in the structure of the actin cytoskeleton of nuclear erythrocytes, like in leukocytes, is responsible for the capability of red blood cells to undergo reactions of migration and phagocytosis.
