Objective: This review focuses on postoral nutrient sensing and signaling as an essential part of the reward system that shapes preferences for the associated flavors of foods.

Summary: There is a critical role for the vagal gut-to-brain axis in motivation and reward. An implication for obesity treatment is that bariatric surgery may alter vagal function.

Usage: Han et al. injected 0.5 µl of CCK-SAP (250 ng/µl) into the R-NG of VGlut2-ires-Cre mice.

Summary: The authors suggest that the dose and timing of antiepileptic medications and other co-medications should always be optimized in order to improve nocturnal sleep and avoid daytime sedation.

Behav Brain Res 414:113452. doi: 10.1016/j.bbr.2021.113452

Objective: To assess the effects of heart failure (HF) on genetic markers of synaptic plasticity in brain areas critical for memory and mood, and to assess the effects of severely reduced ejection fraction (≤40 %) on cognition regulation.

Summary: Collectively, the present findings provide support for the growing consensus that HF is not only a neurohumoral cardiovascular problem but is also a disorder of mood and memory.

Sci Transl Med 13(612):eabg3459. doi: 10.1126/scitranslmed.abg3459 PMID: 34550727

Objective: Hypothesized that enteric glia loss in the premature intestine could lead to dysmotility, exaggerated Toll-like receptor 4 (TLR4) signaling and necrotizing enterocolitis (NEC) development.

Summary: TLR4-induced enteric glia loss leads to experimental NEC through Brain Derived Neurotrophic Factor (BDNF) loss, which can be treated with compound ‘J11.’

Summary: Degeneration of septal cholinergic neurons caused by the immunotoxin 192-IgG-SAP produces a model of the pathological state that occurs in Alzheimer’s Disease. This study investigated whether overexpression of NGF in the hippocampus, where septal neurons send their projections, may reduce the consequences of this damage. Data suggest that NGF overexpression in the hippocampus of rats may partly compensate some 192 IgG-SAP-induced impairments related to cholinergic deficit.

Usage: 192-IgG-SAP or an equivalent volume of PBS (4 µg/site) was administered bilaterally into the ventricles.

Neurotox Res 39(6):1991-2006. doi: 10.1007/s12640-021-00403-4 PMID: 34529240

Objective: To evaluate the role and molecular mechanism of AT2R agonist CGP against Angiotensin II-induced astrocytic activation in primary astrocytes, and in a rat model of hypertension.

Summary: AT2R activation by CGP abrogated Ang II-induced astrocytic activation, by mitigating the ROS production, mitochondrial dysfunction, IκB-α degradation, NFκB nuclear translocation, and release of TNF-α in astrocytes.

Objective: To determine whether tracheal basal cells (BCs) from the dorso-ventral airways have intrinsic molecular and behavioural differences relevant to their in vivo function.

Summary: This study revealed the differences in the characteristics of BCs based on spatial distribution, and also indicated the role of epithelial-mesenchymal interactions in tissue homoeostasis in the trachea. The findings of this study suggest that careful observation is necessary in future research, as the influence of environment on the phenomenon should be considered.
