to examine the mechanism whereby lps enhances fmlp-induced actin polymerization , we determined the predominant end for filament growth in lps- and lps+ cells , the number of actin nuclei generated in lps- and lps+ by fmlp activation , and the number and affinity of fmlp receptors on lps- and lps+ cells by 3 [ h ] fmlp binding .
