Orexin/hypocretin peptides are crucial for arousal and appetite. Recent research highlights their role in attention, cognition, and schizophrenia, influencing antipsychotic drug actions.
Area of Science:
- Neuroscience
- Molecular Biology
- Psychiatry
Background:
- Orexin/hypocretin peptides, discovered a decade ago, play key roles in arousal and appetitive behaviors.
- Recent research has expanded our understanding of their involvement in attention and cognition.
Purpose of the Study:
- To review the current understanding of orexin/hypocretin involvement in schizophrenia.
- To explore the role of orexins/hypocretins in the mechanisms of action of antipsychotic drugs (APDs).
Main Methods:
- Literature review of recent studies on orexins/hypocretins and schizophrenia.
- Analysis of research on the impact of APDs on orexin/hypocretin systems.
Main Results:
- Orexin/hypocretin systems are implicated in cognitive functions relevant to schizophrenia.
- These peptides are involved in how antipsychotic drugs exert their effects.
Conclusions:
- Orexin/hypocretins are significant targets for understanding and potentially treating schizophrenia.
- Further research into orexin/hypocretin pathways is crucial for advancing APD development and efficacy.

Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
