Our studies investigated the effects of Bacillus amyloliquefaciens SC06 on jejunal mitochondria and ER in piglets under the LPS-induced intestinal injury model. Eighteen piglets (male, 21 days old) were randomly assigned to three treatments: CON (basal diet), LPS (basal diet +100 μg/kg LPS), and SC06 + LPS (basal diet +1 × 10 cfu/kg SC06 + 100 μg/kg LPS).

This study investigated the contribution of SARM1 to depressive-like behaviors in a chronic stress-induced depression model and SARM1 knockout (KO) mice. Depressive-like behaviors were assessed using a battery of behavioral tests, including the Open Field Test (OFT), the Forced Swim Test (FST), the Sucrose Preference Test (SPT), and the Tail Suspension Test (TST).

As medications with the potential to prevent and cure liver illness, probiotics have garnered an increasing amount of interest in recent years. The present study used a piglet model with acute liver injury (ALI) induced by lipopolysaccharides (LPS) to investigate the regulatory mechanisms of Bacillus amyloliquefaciens SC06.

The various functional components of RRT suggest that it may theoretically have a stronger potential for alleviating colitis compared to VitC. This study aims to verify whether RRT has a stronger ability to alleviate colitis than equimolar doses of VitC and to explore the mechanisms underlying this improvement.

Cholinergic circuit defects have been linked to various neurological abnormalities, yet the precise mechanisms underlying the impact of cholinergic signaling on cognitive functions, particularly in the context of neuroinflammation-associated, remain poorly understood. Similarly, while the dopamine receptor (D2R) has been implicated in the pausing of cholinergic interneurons (CIN), its relationship with behavior remains inadequately elucidated. In this study, we aimed to investigate whether D2R plays a role in the regulation of fear and memory in the Hsp60 knockout condition, given the non-canonical involvement of Hsp60 in inflammation.

SC06 (SC06) can regulate OS, but its roles in intestinal ER stress remains unclear. Using a 2 × 2 factorial design, 32 weaned piglets were treated by two SC06 levels (0 or 1 × 10 CFU/g), either with or without diquat (DQ) injection.

Genetic knockout and pharmaceutical inhibition of the NLRP3 inflammasome enhances the extinction of contextual fear memory, which is attributed to its role in neuronal and synaptic dysregulation, concurrent with neurotransmitter function disturbances. This study aimed to determine whether NLRP3 plays a role in generalizing fear via the inflammatory axis. We established the NLRP3 KO mice model, followed by behavioral and biochemical analyses.

In addition, dopamine receptors D2 (D2Rs) and glutamate NMDA receptors subtype-NR2B have been implicated in morphine use disorders; however, the molecular mechanism underlying the heteromeric complex of these two receptors in morphine use disorders is unclear. Herein, we focus on interactions between D2R and NR2B in morphine-induced conditioned place preference (CPP) and hyperlocomotion mice models.
