Strong and consistent expression was observed in a limited number of neurons in the head and tail and coelomocytes. Weaker and/or inconsistent expression of TTX-7::EGFP was detected in nerve cord motor neurons, intestine, and somatic gonad. The head neurons expressing
ttx-7::EGFP include AFD and RIA neurons. Also expressed in ASH, ASE, ASJ, AWC, ADF, ADL, ASI, ASK, AWB, VNC motor neurons, etc.
