Summary: Chronic stress and alcohol use disorder have a reciprocal relationship and hinder recovery from both disorders. This study identified the TRPV6 channel as being involved in stress, corticosterone, and alcohol-induced intestinal permeability, microbiota dysbiosis, systemic inflammation, and liver damage. TRPV6 deficiency also blocked the effects of stress and stress-mediated potentiation of alcohol-induced dysbiosis of gut microbiota.

Summary: Lactation overnutrition can lead to obesity and disrupt liver metabolism. Increased levels of glucocorticoids are considered as a mediator for obesity development, and bilateral adrenalectomy can reduce obesity. This study suggests that increased circulating glucocorticoids play a pivotal role in liver and plasma impairments induced by lactation overnutrition in male rats.

Summary: Low-grade inflammation plays a major role in obesity, metabolic syndrome, and the development of type 2 diabetes. The interleukin-1 receptor antagonist (IL-1Ra) is an important natural anti-inflammatory factor involved in glucose homeostasis disturbances. IL-1Ra levels can be used as a potential biomarker for metabolic dysregulation, particularly in prediabetes. Further research is needed to understand the role of IL-1Ra in metabolic abnormalities and its relationship with other lifestyle and metabolic parameters.

Summary: Interleukin-1 (IL-1) is a cytokine that plays a significant role in inflammation and immune response, primarily produced by macrophages during defensive reactions. It belongs to a superfamily of structurally similar proteins and acts through binding to specific receptors on the plasma membrane of target cells. IL-1 family cytokines not only have innate immune and inflammatory effects but also appear to be involved in the development of adaptive immunity in vertebrates.

Summary: The stress experienced during rape may induce ovulation, leading to higher pregnancy rates in raped women than from consensual intercourse. Acute stresses mimic the conditions of rape, releasing adrenal progesterone and central norepinephrine, which can anticipate the LH surge and facilitate conception. The study found that acute stress applied to female rats in a proestrus state increased progesterone levels and activated noradrenergic neurons, resulting in an earlier and enhanced LH surge.

Summary: The IL-1 superfamily of cytokines, consisting of 11 cytokines and 10 receptors, is a crucial regulator of immunity and inflammation. It is tightly regulated through decoy receptor, receptor antagonists, and signaling inhibitors. Inflammation plays a central role in the development of atherosclerosis, and studies have shown the involvement of IL-1 cytokines and receptors in cardiovascular disease pathogenesis.

Summary: The study found that maternal separation enhanced the effect of LPS on the pro-inflammatory cytokine IL-1 beta in the vHi region of the hippocampus in juvenile female rats, while also reducing the dendritic complexity of new neurons. Additionally, both MS and LPS independently decreased the dendritic complexity of new neurons, with MS exacerbating the reduction in complexity caused by LPS in the vHi region.

Summary: Childhood psychological trauma may sensitize stress-related neuroinflammatory systems, increasing the vulnerability to depression and other stress-related mental disorders later in life. Isolating guinea pig pups from the maternal attachment figure for a few hours in a threatening environment can lead to sensitization of inflammatory-mediated, depressive-like behavior and fever during subsequent isolations. Administering the non-selective COX inhibitor naproxen before the initial isolation was found to moderate depressive-like behavior and its sensitization. This study examined the effects of naproxen given after early isolation and found that both doses of naproxen attenuated depressive-like behavior during the third isolation, supporting the potential of anti-inflammatory treatments to mitigate the long-term consequences of early attachment disruption.

Summary: Acute ethanol exposure leads to rapid changes in neuroimmune gene expression, with muted neuroimmune responses in adolescent rats. Growth factor responses to ethanol are similar in adults and adolescents, with decreased BDNF and increased FGF2 expression regardless of age. PDGF is unresponsive to ethanol in adults but shows heightened expression in adolescent males. Ethanol-induced changes in gene expression are independent of PDE4 signaling. Acute ethanol challenge also leads to the suppression of multiple miRNA species in the hippocampus. These findings provide insight into the molecular consequences of heavy drinking in humans.

Summary: This study aimed to determine whether alcohol consumption in later life would influence microglial clearance of A13(1-42). The results showed that aged female rats with a history of ethanol consumption had a higher number of iba1+ cells and marginally reduced expression of A13(1-42), suggesting greater phagocytic activity of A13(1-42) among females after chronic ethanol consumption later in life. In contrast, no significant effects of ethanol consumption were observed on any markers in males.

Summary: In the past decade, neuroinflammatory processes have been found to play a crucial role in substance use disorders. Initially, it was believed that neuroinflammation resulting from prolonged substance misuse contributed to long-term neuropathological consequences. However, it is now understood that the interactions between neuroinflammatory processes and alcohol and drug intake are reciprocal, leading to a vicious cycle that exacerbates the neuropathological effects of drug misuse.

Summary: This study isolates and characterizes six bacteriophages that can infect Ruminococcus gnavus, a gut microbe associated with inflammatory bowel disease. The phages have a temperate lifestyle and can coexist with the host bacterium without causing a significant reduction in its abundance. Analysis of gut virome data reveals a high abundance of these phages in individuals with IBD. This work provides insight into the interaction between phages and R. gnavus in the human gut microbiome.

Summary: A high-fat diet reduces resistance to Listeria monocytogenes, but short-term administration of Akkermansia muciniphila increases resistance to oral and systemic infection of L. monocytogenes in mice fed a high-fat diet. A. muciniphila reduces inflammation in the gut and liver, and normalizes the inflammatory cell infiltration in the ileum. It does not significantly affect the microbiota composition or microbial metabolites.
