CB1-NT immunoreactivity in nodose ganglia from chow fed, weight matched to diet resistant (wmDR), diet resistant (DR) and diet-induced obese (DIO) rats ad libitum fed (ad lib fed; A) or fasted for 24 h (fasted; B). Scale bar: 100 µm. An example of an immunopositive cell (closed arrow) and an immunonegative cell (open arrow) is indicated. Quantitative analysis of CB1-NT immunoreactivity (C) in nodose ganglia from chow fed, weight matched to diet resistant (wmDR), diet-induced obese (DIO), and diet resistant (DR) rats ad libitum fed or fasted for 24 h. Bars represent the mean ± s.e.mean, n = 3–5 per group.* (p < 0.05) and *** (p < 0.001) denote a significant difference to the corresponding ad lib fed group analyzed using unpaired t-test.
