Summary: The study shows that TRIM67 in the hypothalamus responds to body-energy homeostasis and a deficiency of TRIM67 exacerbates metabolic disorders in obese mice induced by high-fat diet. Neuroinflammation and apoptosis were found in the hypothalamus of obese TRIM67 KO mice. Reduced BDNF in the hypothalamus affects sympathetic nervous system innervation and contributes to lipid accumulation under high-fat diet exposure.

Summary: The study found that male mice fed a high-fat diet experience higher neuroinflammation compared to females, likely due to accumulating more visceral fat which serves as a source of pro-inflammatory macrophages that migrate to other tissues, including the hypothalamus. This new connection between adipose tissue and the hypothalamus in obesity contributes to neuroinflammation and hypothalamic pathologies, shedding light on the male bias for neuroinflammation and metabolic syndrome.

Summary: Maternal obesity and poor dietary habits during pregnancy and lactation can have adverse effects on offspring metabolic and neuroimmune development. This study investigated the potential of cannabidiol (CBD) treatment to attenuate the effects of maternal obesity induced by a cafeteria diet on hypothalamic inflammation and peripheral metabolic profile of the offspring. The results showed that CBD treatment reduced white adipose tissue, improved insulin resistance, and reduced inflammation in both the central and peripheral systems.

Summary: This study investigated the effects of an obesogenic diet and parental obesity on behavior, cognition, neuroinflammation, and neuromodulation. The results showed that the obesogenic diet increased locomotor activity, had anxiolytic and antidepressant effects, but impaired short-term and spatial memory. Parental obesity had an effect on spatial memory, neuroinflammation, and specific gene expression.

Summary: This study demonstrates that deletion of the Abi3 gene locus leads to obesity and impaired energy expenditure in mice, and alters gene expression within the hypothalamus, particularly in immune-related pathways. Immunohistological analysis revealed decreased microglia number and area specifically within the mediobasal hypothalamus of mice with Abi3 deletion.

Summary: This study evaluated the effects of prebiotics FOS and GOS on neuroinflammation and cognition in mice fed a high-fat diet. The results showed that FOS and GOS improved blood biochemical parameters, reduced serum IL-1 beta levels, decreased neuroinflammation and apoptosis markers, promoted synaptic plasticity and neurogenesis, and improved spatial learning and memory. In addition, prebiotics modulated the gut microbiota, decreased intestinal inflammation, and improved intestinal barrier function.

Summary: The hypothalamus, a major regulatory center in the brain, is involved in the regulation of aging through hypothalamic neural stem cells (htNSCs). Neural stem cells are important for repairing and regenerating brain cells and rejuvenating the brain tissue microenvironment. Cellular senescence, a state of irreversible cell cycle arrest, is associated with neuroinflammation, which can be upregulated by obesity. Obesity has been shown to accelerate aging, highlighting the need to study the dysregulation of htNSCs in obesity and develop strategies to address obesity-induced comorbidities associated with brain aging. This review will summarize hypothalamic neurogenesis in obesity and explore the potential of NSC-based regenerative therapy for obesity-induced cardiovascular conditions.

Summary: The consumption of 'western'-style diets and sedentary lifestyles have led to a global epidemic of obesity, with maternal obesity, overnutrition, and unhealthy dietary patterns having lasting adverse effects on offspring's physical and mental health. Studies suggest that maternal overnutrition may disrupt offspring cognitive function, affective state, and psychosocial behavior through mechanisms such as neuroinflammation, disrupted neuronal circuities, dysregulated brain hormones, and changes in gut microbiota. Further research is needed to explore the specific pathways shaping abnormal behavior in offspring in the context of maternal obesogenic diet exposure.

Summary: Alzheimer's disease (AD) is a growing epidemic with significant social and economic burden. Inflammation and neurodegeneration play a major role in AD pathogenesis. This review focuses on the effects of dietary supplementation in AD-like animal models, specifically in relation to neuroinflammation induced by lipopolysaccharide (LPS) injection. Various compounds, such as curcumin and krill oil, have been found to counteract cognitive decline and neuroinflammatory responses in rodents. Overall, dietary interventions offer potential neuroprotection and immune regulation in AD.

Summary: Obesity is a major risk factor for Alzheimer's disease and related dementias. The link between obesity and the neurodegenerative processes of dementias is not fully understood, but recent research suggests that obesity-related inflammation may contribute to neuroinflammation. This review highlights the need to bridge the gap between animal microscopy and human MR imaging studies.

Summary: Obesity, depression, and Alzheimer's disease are three major interrelated modern health conditions. Depression may increase the risk of Alzheimer's disease, while obesity is also associated with an increased risk of Alzheimer's disease. Chronic inflammation plays a key role in linking obesity, depression, and Alzheimer's disease.

Summary: Hypoglycemia, a common consequence of diabetes treatment, is associated with severe morbidity and mortality and has become a major barrier to intensifying antidiabetic therapy. Dementia generally refers to the loss of memory, language, problem-solving, and other cognitive functions, which can interfere with daily life, and there is growing evidence that diabetes is associated with an increased risk of both vascular and non-vascular dementia.

Summary: This study examined inflammatory markers and serotonergic dynamics in co-morbid obesity and depression, finding that a high-fat diet led to obesity and depressive-like symptoms in rats, marked by increased pro-inflammatory cytokines in the hippocampus. Additionally, impaired response to escitalopram in the hippocampus of obese rats was linked to elevated neuroinflammation and increased serotonin transporter expression.

Summary: Optical coherence tomography (OCT) is a non-invasive method that can be used to rapidly and quantitatively examine the integrity of the neuroretina. It has been shown that OCT can be used to observe retinal thinning in patients with childhood dementia, and to assess the improvement of retinal structure after treatment. Furthermore, OCT can provide insights into other childhood dementias based on the correlation between retinal and brain degeneration in Sanfilippo syndrome.

Summary: This study investigated the effects of EAE induction on thymopoiesis and T cell development, revealing changes such as increased apoptosis, decreased proliferation, and a blockade in the transition from double-negative thymocytes to double-positive cells. It was also found that positive selection was disrupted in the thymus of EAE mice, along with an increased production of regulatory T cells.

Summary: Degenerative cervical myelopathy (DCM) is a neurological condition characterized by chronic compression of the cervical spinal cord, leading to impaired limb function. While respiratory dysfunction is not a common symptom of DCM, it can affect the ventilatory response to respiratory challenges. Surgical decompression improves sensorimotor function in DCM, but its impact on respiratory function is unclear. This study evaluates respiratory function and adaptive ventilation in a DCM model, showing that DCM impairs acute adaptive ventilatory ability and surgical decompression does not fully restore it.
