Localization of orexin B and orexin-2 receptor in the rat epididymis

Acta Histochemica, 2018
The peptides orexin A (OXA) and orexin B (OXB) derived from the proteolytic cleavage of a common precursor molecule, prepro-orexin, were originally described in the rat hypothalamus. Successively, they have been found in many other brain regions as well as in peripheral organs of mammals and other less evolved animals.

Psychedelics, entactogens and psychoplastogens for depression and related disorders

British Journal of Pharmacology, Volume 183, Issue 14, Page 3897-3919, July 2026.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

Circadian‐Related Serotonin/Melatonin Level Modulates Cisplatin Ototoxicity Susceptibility Depended on NOS3–NO Pathway

Journal of Pineal Research, Volume 78, Issue 4, July 2026.
ABSTRACT Hearing impairment is attributed to factors such as age, genetic predisposition, and environmental influences, among which environmental factors are considered modifiable. Among various environmental factors, the role of poor lifestyle habits is particularly critical, yet the specific mechanisms by which they contribute to hearing damage ...

Structure−Activity Studies of Orexin A and Orexin B at the Human Orexin 1 and Orexin 2 Receptors Led to Orexin 2 Receptor Selective and Orexin 1 Receptor Preferring Ligands

, 2016
The neuropeptides orexin A and B (also known as hypocretins) play an important role in many physiological and behavioral activities. Orexins are ligands of two closely related G-protein-coupled receptors, that are the named orexin 1 and orexin 2 ...

Azulene-based compounds for targeting orexin receptors [PDF]

, 2018
A library of 70 000 synthetically accessible azulene-based compounds was virtually screened at the OX2 receptor. Based on the results, a series of azulene derivatives was synthesized and the binding to and activation of both orexin receptor subtypes were

Investigation of New Orexin 2 Receptor Modulators Using In Silico and In Vitro Methods

Molecules, 2018
The neuropeptides, orexin A and orexin B (also known as hypocretins), are produced in hypothalamic neurons and belong to ligands for orphan G protein-coupled receptors.

Stress, stress systems, and Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract Stress is increasingly recognized as an important, modifiable factor for Alzheimer's disease (AD), yet its roles in initiation, progression, and outcomes remain incompletely elucidated. Epidemiologic studies link chronic stress, early‐life adversity, and trauma to increased AD risk, while experimental models have uncovered mechanisms by which ...

Differential actions of orexin receptors in brainstem cholinergic and monoaminergic neurons revealed by receptor knockouts: implications for orexinergic signaling in arousal and narcolepsy

Frontiers in Neuroscience, 2013
Orexin neuropeptides influence multiple homeostatic functions and play an essential role in the expression of normal sleep-wake behavior. While their two known receptors (OX1 and OX2) are targets for novel pharmacotherapeutics, the actions mediated by ...
