From dysphoria to depression. The role of dynorphins and kappa opioid receptors in the pathophysiology of stress related disorders [PDF]
Stres jest złożonym zjawiskiem, które wywiera wpływ na zdrowie i funkcjonowanie jednostki. Dynorfiny i receptory opioidowe kappa stanowią część endogennego systemu, który kontroluje homeostazę organizmu.

We determined the effects on nociceptive threshold and motor function of dynorphin-gene products, dynorphin A-(1-32) (DYN A-(1-32), DYN A-(1-8), DYN B and DYN B-29 and the non-opioid peptides somatostatin, neurotensin and salmon calcitonin (s-CT) after ...

Opioid and non-opioid activities of the dynorphins
Endogenous opioid peptides a-neoendorphin, dynorphin A (Dyn A), dynorphin B (Dyn B) and big dynorphin (Big Dyn) consisting of Dyn A and Dyn B, collectively known as dynorphins are derived from the precursor protein prodynorphin (PDYN).

Background: Since kisspeptin (KISS1) in the hypothalamus is affected by the inhibitory effect of dynorphin, it raises questions about the controlled balance of these 2 neuropeptides in women with and without polycystic ovary syndrome (PCOS).

Opioid Modulation of Major Neurotransmitter Systems: Acute, Chronic, and Withdrawal Effects
Opioids are widely used but also frequently misused drugs that affect multiple neurotransmitter systems, including dopaminergic, glutamatergic, GABAergic, serotonergic, and cholinergic pathways. Opioid‐induced neuroadaptations depend on the duration of drug exposure, with distinct changes also emerging following drug discontinuation.

Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]
Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.

Repeated Administration of Norbinaltorphimine Produces Cumulative Kappa Opioid Receptor Inactivation
Kappa receptor activation by dynorphins contributes to the anxiogenic, dysphoric, and cognitive disrupting effects of repeated stress, suggesting that kappa receptor antagonists might have therapeutic utility in the treatment of stress disorders.

Abstract Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome, affects 10%–13% of women of reproductive age and remains underdiagnosed despite its substantial health burden. The introduction of the new PMOS nomenclature in 2026 reflects a fundamental shift in understanding the condition as a lifelong endocrine ...

Abstract The neuromodulatory subcortical system (NSS) includes thermoregulatory neurons that maintain core body temperature (Tb) and brain temperature within a narrow, diurnally varying range. Cellular pathways in NSS neurons implicated in Alzheimer's disease (AD) may be vulnerable to Tb rhythm disturbance because of their sensitivity to temperature ...

Calcium influx into phospholipid vesicles caused by dynorphin neuropeptides
Dynorphins, endogeneous opioid peptides, function as ligands to the opioid kappa receptors but also induce non-opioid excitotoxic effects. Dynorphin A can increase the intra-neuronal calcium concentration through a non-opioid and non-NMDA mechanism.
