Anti-Ly6G does not change LTB4 receptor sensitivity or LTB4-induced Ca2+ flux. (A) Purified neutrophils were loaded with Fura 2AM for 30 minutes at 37°C. Cells were then washed and pretreated with isotype or anti-Ly6G (10 μg for 10 minutes), and the Ca2+ concentration was monitored continuously with a Hitachi F-4500 calcium fluorometer from 0-200 seconds. LTB4 at 100, 1, or 0.1nM was added 50 seconds after reading. Shown is the isotype (Iso) and anti-Ly6G overlap. (B) BM cells were pretreated with isotype or anti-Ly6G (10 μg for 10 minutes) and neutrophil migration toward LTB4 at a range of concentrations was evaluated after 3 hours using flow cytometry. Results are representative of 2 independent experiments. *P < .05.
