Abstract Background: Glucocorticoids are used as anti-inflammatory drugs for the treatment of various diseases, however, their side effects on normal brain tissue remain underinvestigated. Objectives: The study aimed to investigate dexamethasone (DXM) effects on cell composition and myelin content in the mouse brain tissue. Methods: C57Bl/6 male mice (n = 60) received single and ten multiple intraperitoneal DXM injections (2.5 mg/kg), and the studied parameters were analysed at 1, 3, 7, 10 days after a single DXM injection and 15, 30, 60, and 90 days after the multiple injections. Oligodendrocytes, microglia, and astrocytes were assayed by immunohistochemistry… More >

Abstract Background: Mitochondrial dysfunction plays a critical role in the pathogenesis of Alzheimer’s disease (AD). Resveratrol is a promising compound for the treatment of various neurodegenerative diseases, including AD. Aims: To investigate mitochondrial damage and the effects of resveratrol on inflammation, cognitive function, and mitochondrial quality control in APP/PS1 mice. Methods: Comparative analysis of mitochondrial DNA (mtDNA) damage was conducted between 10-month-old APP/PS1 mice and age-matched C57BL/6 mice. Assessments included measurement of amyloid-β levels, inflammatory markers, swimming distance in the Morris water maze, and gut microbiome composition. Resveratrol’s effects on cytokine expression, mtDNA levels in plasma, and… More >

Abstract Background: Myocardial infarction (MI) is known worldwide for its important disabling features, including myocarditis and cardiomyocyte apoptosis. It is believed that microRNA (miRNA) has a role in the cellular processes of apoptosis and myocarditis, and miR-219a-5p has been found to suppress the inflammatory response. However, unknown is the precise mechanism by which miR-219a-5p contributes to MI. Methods: We measured the expression of miR-219a-5p and evaluated its effects on target proteins, inflammatory factors, and apoptosis in a mouse model of MI. Echocardiography was utilized to examine the MI clinical index, and triphenyl tetrazolium chloride staining was More >

Abstract Background: Women with obesity have higher risk of adverse pregnancy outcomes, including preeclampsia (PE). Late-gestational hypertension, aberrant fetoplacental development, and fetal growth restriction (FGR), hallmarks of PE, are observed spontaneously in BPH/5 mice. Similar to obese preeclamptic women, BPH/5 mice have higher visceral white adipose tissue (WAT) and circulating leptin. We hypothesized that attenuation of maternal obesity and serum leptin in pregnant BPH/5 mice will improve fetoplacental development by decreasing hypoxia markers and leptin expression at the maternal-fetal interface. Methods: To test this hypothesis, BPH/5 mice were fed ad libitum (lib) and pair-fed (PF) to C57… More >

Abstract Spinal cord injury (SCI) remains an intractable clinical challenge of neurosurgery, it can be divided into two stages: uncontrollable primary injury induced by mechanical damage and controllable secondary injury regulated by continuous cell death. The apoptosis was the one of most important events in secondary injury, previous studies revealed that excessive endoplasmic reticulum (ER) stress breaks down the homeostasis and triggers apoptosis in the spinal cord. To deter or alleviate the secondary jury, we screen one of fat-soluble compounds, salubrinal, which was an inhibitor of eIF2α dephosphorylation can repair SCI by inhibiting ER stress in… More >

Abstract Glioblastoma is a lethal disease featuring a high proliferation of tumor cells, excessive angiogenesis, and heavy drug resistance. The overall survival of glioblastoma patients has been dismal, even with an intensive standard of care. Recent advances in immune checkpoint blockades are changing the treatment of cancers. However, the efficacy of immune checkpoint blockades in glioblastoma is still unclear. Here we investigated the roles of CD103⁺ cells in regulating the effect of immune checkpoint blockades in glioblastoma mouse models. Our findings indicated that the murine glioblastoma model was not sensitive to immune checkpoint blockades. Flt3L, a growth More >

Abstract Depression is often preceded by exposure to stressful life events. Chronic stress causes perturbations in the immune system, and up-regulates production of proinflammatory cytokines, which has been proposed to be associated with the pathogenesis of clinical depression. However, the potential mechanisms by which stress-induced proinflammatory cytokines lead to the development of depression are not well understood. Here, we sought to screen the main proinflammatory cytokines and the potential mechanisms linking inflammation to depression-like behavior during unpredictable, chronic, mild stress (UCMS), in vivo. Mice were allocated into four groups in each separate experiment: saline-control, saline-UCMS, drug-control… More >

Abstract Interleukin (IL)-7 is thought to be a non-redundant cytokine for lymphopoiesis as there is a reduction of T and B cells in peripheral blood (PB) and a loss of TCRγδ⁺ cells in PB and bone marrow (BM) in IL-7^-/- mice. To investigate whether the absence of IL-7 influences the organ-dependent distribution of the lymphocytes, we analyzed single cell suspensions of several organs (BM, lung, liver, small intestine, and spleen) at different ages (three and 12 months) of IL-7^+/+ and IL-7^-/- mice using flow cytometry; immunohistochemical staining was performed on frozen sections of various organs. We observed lymphocytopenia… More >

Abstract Nutritional deficiencies are associated with impaired immune response, affecting the body’s defence mechanisms. It is also known that Lactic Acid Bacteria (LAB) and fermented products such us yogurt have immunopotentiator activity and nutritional properties, and could thus be used as a valuable supplement in a renutrition diet. The aim of this study was to determine, in a non-severe malnutrition model, the effective dose of Lactobacillus casei (L.casei), which when is used as an adjuvant in a renutrition diet, would modulate the mucosal immune system and induce recovery of the integrity of the intestinal barrier. The experiments… More >
