Effects of PM _2.5 exposure on inflammation in blood, bone marrow and spleen in KKay mice. (A), Identification of CD11b⁺Gr-1^low7/4^hi cells from mice blood, bone marrow and spleen at the end of 5-week PM_2.5 exposure. (B-D), Analysis of the CD11b⁺Gr-1^low7/4^hi population in blood (B), bone marrow (C) and spleen (D). (E), mRNA levels of INFγ and IL-4 in cultured spleen cells treated with anti-CD3 at the end of 8 wks of PM_2.5 exposure. *P < 0.05 compared to respective FA group, # P < 0.05 compared to respective group before treatment. n = 7-8 per group.
