Macropinocytosis provides an efficient sampling mechanism for fluid phase or non- binding antigens. Since macropinosomes have lower surface/volume ratios than mall vesicles, more extracellularfluid is sampled per unit membrane internalized (Steinman and Swanson, 1995).en-USVeterinary ScienceVeterinary MicrobiologyArticle
