Ovalbumin (OVA) inhalation increases acid responsiveness in nodose neurons. A and B: fluorescence images of nodose neurons activated with acid (pH 6.4, 5.4, and 4.4) and KCl (50 mM) from naïve and OVA inhalation (OVA) guinea pigs. C: representative traces of nodose neurons from naïve (left) and OVA inhalation (right) guinea pigs that were activated by acid (pH 6.4, 5.4, and 4.4) and KCl (50 mM). D: summary of percentages of acid-responsive nodose neurons in all KCl-responsive nodose neurons from naïve (N = 6) and OVA inhalation (N = 4) guinea pigs. **P < 0.01 and ***P < 0.001 are the levels of significance for naïve vs. OVA inhalation (2-tailed unpaired t-test).
