For
sprr-2, we observed expression in around 10 neuron pairs in the head, of which the cellular identity was confirmed for the main salt-sensory ASE neurons as well as the ASI and AWB chemosensory neurons. In addition,
sprr-2 expression localized to the SDQ neurons in the midbody and was also evident in 3 tail neurons, one of which corresponds to the DA8 or DA9 motor neuron.
