the last two responses , however , failed to occur in cells that were ( a ) calcium depleted , ( b ) treated with high activator concentrations ( which inhibited virtually all paf binding and paf-induced ca2+ transients ) , or ( c ) treated with paf 5 min before a pkc activator ( paf-induced rises in cytosolic ca2+ reversed in less than 5 min ) .
