We also took advantage of the HH pathway inhibition paradigm, in treating Phox2b-Cre; Rosa26LSL−TdTomato mice, hence forth called Phox2b-Cre; TdTomato mice, by oral gavage with the smoothened antagonist sonidegib, to eliminate TB and CT chemical taste responses, with retention of CT somatosensory responses (Kumari et al. 2015). Here, PHOX2B is linked to tuberculosis.
