## Abstract The polymerization of globular actin to fibrous actin which occurs when sperm are activated, was not inhibited by cytochalasinโB. The acrosomal filaments and its component actin filaments formed in the presence of cytochalasinโB; and once formed, the actin filaments did not depolymerize

We have previously reported that a physiological range of shear stress induces neutrophil homotypic aggregation mediated by lymphocyte function-associated antigen-I (LFA-1) and intercellular adhesion rnolecule-3 (ICAM-3) interactions. To further characterize the homotypic aggregation, actin polymeri
## Abstract The spectrinโ4.1โactin complex isolated from the cytoskeleton of human erythrocyte [3] was found to be similar to muscle Fโactin in several aspects: Both the complex and Fโactin nucleate cytochalasinโsensitive actin polymerization; both bind dihydrocytochalasin B with similar binding co
