Abstract

In contrast to intact human erythrocytes, human erythrocyte ghosts can be agglutinated but not fused by Sendai virus. Membrane fusion can, however, be induced in virus-agglutinated erythrocyte ghosts by addition of proteolytic enzymes such as trypsin, papain, or Pronase. When erythrocyte ghosts were reacted with antispectrin antiserum, the antiserum inhibited both the induction of fusion and the proteolysis of the membrane spectrin. The correlation between the membrane fusion process and the membrane cytoskeleton is discussed.
