... and the neuropeptide, TPep-NLS. Further,four CBF stimulants (zero external Cl - , depolarization, dopamine and TPep-NLS) depend on a common mode of action, viz . Ca 2+ influx, possibly through voltage-gated Ca 2+ channels, and can be blocked by nifedipine. Ca 2+ influx alone, however, does not provide all the internal...

... is that the Pd6 and Pd5 neurons both synthesize a trio of 15-amino-acid neuropeptides known collectively as TPeps(Lloyd et al., 1996). Immunohistological studies localized TPep in ciliated structures such as the foot epithelium and oviduct (Willows et al., 1997). Ultrastructural studies further localized TPep...
