Background:

Peptidergic substances (neurosecretions) have a historical association with nematode molting.
Recent research shows peptide immunoreactivities localized within the nematode nervous system, renewing interest in neurobiology.

Purpose of the Study:

To review progress in isolating nematode neuropeptides.
To elucidate the physiological actions and inactivation mechanisms of these neuropeptides.
To suggest future research directions and therapeutic applications.

Main Methods:

Review of existing literature on nematode neuropeptide isolation.
Analysis of studies on neuropeptide function and regulation.
Exploration of potential therapeutic targets within peptidergic pathways.

Main Results:

Progress in isolating and identifying various nematode neuropeptides.
Understanding of some neuropeptides' roles in physiological processes.
Identification of mechanisms involved in neuropeptide inactivation.

Conclusions:

Nematode neuropeptides are crucial regulators of physiological processes, including molting.
Further research is needed to fully understand their complex roles and inactivation.
Neuropeptide pathways offer promising avenues for developing novel therapeutic strategies against nematodes.
