TAMs and T-PEMs differ in their regulation of T cell proliferation and their phagocytosis capabilities. (A) Analysis of ex vivo proliferation of αCD3/αCD28/IL-2-activated T splenocytes from normal mice in the absence or the presence of N-PEMs, T-PEMs and TAMs; columns represent mean of four different experiments with similar results. (B) Analysis of the ability of N-PEMs, T-PEMs and TAMs to internalize fluorescent Zymosan particles using fluorescence microscopy, with and without pre-treatment with phagocytosis-interfering Cytochalasin-D; columns show mean of four different experiments with similar results.
