Heparin Interaction with the Primed Polymorphonuclear Leukocyte CD11b Induces Apoptosis and Prevents Cell Activation

Figure 6

CD11b expression on primed PMNLs. CD11b expression on NC PMNLs after 15 min stimulation with 10⁻⁶M PAF without an additional treatment (1) and with 30 min incubation with 25 U/mL heparin (2). Apoptosis was evaluated by the TUNEL method (FITC green staining). Nuclei were stained with Hoechst reagent (blue staining).
