Although changes of cytoskeleton (CSK) stiffness and friction can be induced by diverse interventions, all mechanical changes reported to date can be scaled onto master relationships that appear to be universal. To assess the limits of the applicability of those

We studied a number of parameters, which may all depend upon cytoskeletal function, comparing lymphocytes and granulocytes (PMN) from young and old healthy donors. F-actin content was measured by NBD-phallacidin staining, followed by flow cytometry and was expressed as mean

The traditional methods of measuring F-actin content in neutrophils required a large blood sample and a series of isolation procedures. To reduce the disturbing effect on neutrophils, a new method was designed to measure the neutrophil F-actin content directly in
