Fig 3. Single cell reverse transcription polymerase chain reaction of labeled nodose/jugular neurons for detection of toll-like receptor (TLR).

A. The percentage of the TLR2 expressing neurons (29.5%) was significantly higher in the bleomycin-induced fibrosis model compared to the control group (9%; *P < 0.05; χ²-test). B. The percentage of the TLR5 expressing neurons (55.7%) was significantly higher in the bleomycin-induced fibrosis model compared to the control group (15.1%; *P < 0.05; χ²-test).
