Summary: Our study found that inhibiting hippocampal neuroinflammation not only reduces inflammatory responses in the hippocampus but also improves brain functional connectivity in regions related to the hippocampus. Early anti-inflammatory treatment with SS-31 has a long-lasting effect on reducing the impact of LPS-induced neuroinflammation.

Summary: The study shows that GLC can effectively reduce brain edema, improve neurofunction deficits after ICH, increase brain-derived neurotrophic factors, and decrease proinflammatory factors. GLC reduces IKK expression in microglia and NF-κB-P65 levels in perihematomal tissue. GLC alleviates ICH-induced neuroinflammation and improves neurological outcomes in aged rats by regulating the NF-κB signaling pathway through the Sur1-Trpm4 channel.

Summary: The etiology of Parkinson's disease (PD) is still unknown, but oxidative stress and neuroinflammation play a crucial role in its pathogenesis. This study found that lipopolysaccharide (LPS)-induced neuroinflammation and rotenone (ROT)-induced oxidative stress synergistically aggravated motor dysfunction, dopamine neuron damage, glial cell activation, release of related mediators, activation of Nrf2 signaling, and disruption of oxidative balance in the rat brain. Furthermore, oxidative stress followed by neuroinflammation caused more dopamine neuronal loss than neuroinflammation followed by oxidative stress.

Summary: It has been found that neuroinflammation is crucial in various neurological and psychiatric disorders. Recent studies have shown that diffusion MRI (dMRI) can detect changes in microglial density and morphology related to neuroinflammation, but these studies were mostly conducted ex vivo or in extreme animal models. In this study, the utility of established dMRI methods to detect neuroinflammation in a clinically relevant animal model of sickness behavior was investigated. The results demonstrated that diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) indicated widespread increases in diffusivity in the brains of rats with a lipopolysaccharide challenge. These findings confirm the sensitivity of dMRI to neuroinflammatory processes and contribute to the development of a noninvasive indicator of neuroinflammation for early diagnosis and treatment monitoring in neurological and psychiatric diseases.

Summary: Cerebellar dysfunction, which is related to impaired motor coordination and balance, may be influenced by neuroinflammation and aging. This study showed that chronic neuroinflammation in aged mice led to mitochondrial dynamic alteration in the cerebellum, with changes in fusion and fission-related genes. The findings suggest that the interaction between mitochondrial dynamics and activated microglia under chronic neuroinflammatory conditions is crucial for understanding the molecular mechanism of the cerebellum.

Summary: This study demonstrates that developmental exposure to low doses of diazinon has persistent and evolving effects on behavior and neurochemistry in rats, particularly as they enter middle age. The effects of diazinon on locomotor activity diminish with age, but deficits in reference memory and attentional accuracy emerge in middle-aged rats. These long-term behavioral impairments are associated with alterations in dopaminergic function.

Summary: This study investigated the effects of low-dose aluminum exposure on the oxidative biochemistry, proteomic profile, and morphology of the major salivary glands. The results showed that aluminum caused oxidative imbalance, dysregulation of protein expression, and histological alterations in the salivary glands. Prolonged exposure to low doses of aluminum may pose a risk to oral health.

Summary: This study investigated the effects of Gal-3 inhibition on neuroinflammation and cognitive deficits in aged mice with LPS-induced neurotoxicity. The results showed that Gal-3 knockdown in the hippocampus attenuated neuroinflammation and neuronal apoptosis, leading to improved cognitive function. Furthermore, the study suggested that Gal-3 may exert its effects through inhibiting the TLR4/NF-kB pathway. These findings highlight the potential therapeutic target of Gal-3 against AD-associated neuroinflammation.

Summary: The study reveals that astrocytic GluN2A plays a critical role in exerting protective effects on synapses by regulating NGF against A beta synaptotoxicity, through modulating pNF-kappa B, Furin, and VAMP3 to control NGF synthesis, maturation, and secretion. This discovery may contribute to establishing new targets for Alzheimer's disease prevention and early therapy.

Summary: COVID-19 infection may increase the risk of cognitive impairment, so further research is needed to study the symptoms, genetic polymorphisms, and treatment decisions associated with cognitive impairment risk, and to establish research consortia to monitor long-term consequences. Additionally, the lack of model systems to test hypotheses related to infection and cognition is a pending issue.

Summary: The study demonstrated that activation of astrocytic NMDARs can mitigate A beta-induced loss of synaptic proteins by increasing NGF release, while blockade of astrocytic NMDARs inhibits A beta-induced compensatory protective NGF increase. This highlights the important role of NMDARs in neurodegenerative diseases.

Summary: Systemic perturbations following surgical trauma can lead to a neuroimmune cascade, affecting the blood-brain barrier, activating microglia, and contributing to cognitive deficits such as delirium. Delirium superimposed on dementia is a severe complication that increases the vulnerability of the brain to neuroinflammation and neurodegeneration, with molecular mechanisms not yet fully understood. In this study, using a mouse model, the researchers found that the brain-penetrant anti-inflammatory neuroprotective drug URMC-099 could prevent inflammatory endothelial activation, breakdown of the blood-brain barrier, synapse loss, and microglial activation in the delirium superimposed on dementia model.

Summary: Inflammatory stress during anesthesia and surgery can lead to long-term cognitive dysfunction in the vulnerable aged brain. This study focused on the network mechanism of this dysfunction and found that the default mode network (DMN) plays a significant role. Changes in both topology structure and functional connectivity (FC) of DMN were observed in aged rats following inflammatory stress-induced cognitive dysfunction. The alterations in FC were long-lasting, while changes in topology structures only lasted for 3 days.

Summary: Delirium is a common, morbid, and costly syndrome closely associated with Alzheimer's disease (AD) and AD-related dementias (ADRD). While human studies have improved our understanding of delirium in terms of incidence, risk factors, outcomes, and management, limited knowledge exists about the neurobiology of delirium. This article discusses the use of preclinical and translational animal models to advance our understanding of delirium neurobiology and develop new prevention and treatment strategies. Recommendations for the development and validation of these models are provided to enhance awareness in this important field.

Summary: Despite limited evidence for SARS-CoV-2 infection in the central nervous system, cognitive impairment is a common complication in recovered COVID-19 patients. In this study, nanocrystal quantum dot micelles decorated with spike protein were used to investigate neurological damage caused by SARS-CoV-2. The findings provide evidence of an inflammatory response in brain cells without direct exposure to SARS-CoV-2-like nanoparticles and suggest potential neuroprotective strategies.

Summary: Resting-state functional magnetic resonance imaging (rs-fMRI) is a promising method for studying brain function, typically performed on anesthetized animals. This study found that different anesthesia methods in aged rats can lead to variations in functional connectivity in different brain regions. Isoflurane anesthesia may be a suitable substitute for Isoflurane + Dexmedetomidine anesthesia in default mode network studies, depending on the regions of interest.
