The phagocytosis-associated chemotaxis of human mononuclear leucocytes from peripheral blood is not antitubulin-sensitive.

Lymphoprep-isolated and glass-adherent mononuclear leucocytes (L-MNs) from the peripheral blood of healthy donors appeared to display directional locomotion towards sparsely distributed yeast cells during continuous observation in coverslip preparations and during observations by means of time-lapse filming in Rose chambers. The phagocytosis-associated L-MN chemotaxis was not inhibited by antitubulin concentrations which were antichemotactic thesis that a direct antitubulin-insensitive chemotaxis exists in L-MNs, besides the antitubulin-inhibited L-MN chemoataxis reported in a previous study.
