nPM rapidly induced cytokine mRNA in ex vivo olfactory neuroepithelium. a, c Incubation with nPM (12 μg/ml, 2 h) increased TNFα mRNA by 50 % and Iba1 by 20 % (*p < 0.05; t test; n = 7). b, d IL-1α and TNFR1 (p = 0.079, 0.058, respectively). GFAP mRNA was below reliable PCR values (OE Ct >30 vs cerebral cortex Ct <24, positive control)
