Flow cytometry analysis of expression of NK1R in mouse blood leukocytes. a Representative graphs of percentages of NK1R⁺ leukocytes in the blood of non-sensitized and sensitized mice, respectively. (A) and (D) are fluorescence minus one (FMO) for NK1R; (B) and (E) are all fluorescence (AF) of NK1R⁺ leukocytes treated with normal saline (NS); (C) and (F) are all fluorescence (AF) of NK1R⁺ leukocytes treated with SP. b Demonstrates median percentage values of NK1R⁺ leukocytes in mouse blood. The data shown are the median (range) value from six different mice. *P < 0.05 in comparison with a corresponding non-sensitized group (paired Mann–Whitney U test)
