title: Cell migration/chemotaxis: biphasic dose responses.
abstract: The dose-dependent effects of chemoattractants on target cell migration such as tumor cells, fibroblasts, and especially neutrophils were assessed. In general, the dose-response characteristics were strikingly biphasic in nature and were independent of both the target tissue and chemoattractant agent. The assessment included evaluations of the quantitative features of the dose-response relationship, mechanistic foundations of the biphasic responsiveness and clinical applications.
