Dual action of serotonin on local excitatory and inhibitory neural circuits regulating the corticotropin-releasing factor neurons in the paraventricular nucleus of the hypothalamus

18 views | Dec 16 2023

Serotonin modulates corticotropin-releasing factor (CRF) neurons in the paraventricular nucleus of the hypothalamus by upregulating glutamatergic interneurons via 5-HT7 receptors and downregulating GABAergic interneurons via 5-HT2C receptors, as demonstrated in an electrophysiological study using the CRF-modified yellow fluorescent protein (Venus) ΔNeo mouse model.

Nuciferine protects against lipopolysaccharide-induced endometritis via inhibiting ferroptosis and modulating AMPKα/mTOR/HIF-1α signaling axis

34 views | Nov 16 2023

Nuciferine (NF) demonstrates protective effects against lipopolysaccharide (LPS)-induced endometritis in mice by modulating multiple pathways, including MyD88/NF-κB, MAPK, ferroptosis, and the AMPKα/mTOR/HIF1α signaling axis, while also exerting direct anti-inflammatory effects in endometrial epithelial cells through the inhibition of the NF-κB signaling pathway.

Antidepressant efficacy of cariprazine in bipolar disorder and the role of its pharmacodynamic properties: A hypothesis based on data

74 views | May 04 2023

The study investigated whether the pharmacodynamic properties of cariprazine fit into a previously developed model for the treatment of bipolar depression, which was based on a combination of clinical and preclinical data, and found that its properties fit well with the proposed model, but further clarification is needed regarding its norepinephrine reuptake inhibition.

Can pharmaceutical pollution alter the spread of infectious disease? A case study using fluoxetine

93 views | Feb 17 2023

Fluoxetine exposure affects the severity of a bacterial infection in water fleas in a non-monotonic manner, but the effect varies with both the infection outcome measured and the genotype of the pathogen, leading to complex genotype-by-environment interactions in its influence on disease dynamics.

Antidepressant drugs use and epilepsy risk: A nationwide nested case-control study

64 views | Feb 16 2023

A case-control study in Taiwan found a higher risk of epilepsy among patients exposed to antidepressants, particularly with longer-term use, and showed a higher risk for escitalopram, venlafaxine, mirtazapine, paroxetine, and fluoxetine, but not for sertraline, fluvoxamine, citalopram, duloxetine, milnacipran, and bupropion.

5-HT4 receptors facilitate cholinergic neurotransmission throughout the murine gastrointestinal tract

1045 views | Dec 11 2018

Pauwelyn V et al. showed that in the murine gastrointestinal tract, activation of 5-HT4 receptors with prucalopride enhances cholinergic contractions, illustrating facilitation of myenteric cholinergic neurotransmission. The degree of enhancement with prucalopride is of similar magnitude as previously reported in other species, but the effective concentrations are lower than those needed in the gastrointestinal tract of other species.
