Comparison of tdTomato expression, α-TRPV1 immunoreactivity, α-TRKA immunoreactivity, and α-TRKB immunoreactivity in vagal ganglia of TRPV1-tdT and Tac1-tdT. A, The relative contribution of jugular (orange bars) or nodose (blue bars) neurons to the vagal neuronal populations expressing α-TRKA immunoreactivity (αTRKA+), α-TRKB immunoreactivity (αTRKB+), α-TRPV1 immunoreactivity (αV1+), or tdTomato in either the Tac1-tdT or the TRPV1-tdT. B, The percentage of specific neuronal groups in the nodose (blue) or jugular (orange) ganglia with α-TRKA immunoreactivity. C, The percentage of specific neuronal groups in the nodose (blue) or jugular (orange) ganglia with α-TRKB immunoreactivity. D, The percentage of neurons expressing either α-TRKA immunoreactivity (αTRKA+) or α-TRKB immunoreactivity (αTRKB+) in the nodose (blue) or jugular (orange) ganglia with tdTomato expression in the Tac1-tdT ganglia. E, The percentage of neurons expressing either α-TRKA immunoreactivity (αTRKA+) or α-TRKB immunoreactivity (αTRKB+) in the nodose (blue) or jugular (orange) ganglia with tdTomato expression in the TRPV1-tdT ganglia. Data are derived from n = 3 animals in each strain.
