Cedrol supplementation ameliorates memory deficits by regulating neuro-inflammation and cholinergic function in lipopolysaccharide-induced cognitive impairment in rats. Heliyon 2024; 10:e30356. [PMID: 38707398 PMCID: PMC11068808 DOI: 10.1016/j.heliyon.2024.e30356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 04/14/2024] [Accepted: 04/24/2024] [Indexed: 05/07/2024] Open
Abstract
Background Cedrol, a sesquiterpene alcohol, is found in a high amount in several conifers. It possess several beneficial health effects, including antioxidant and anti-inflammatory properties. Objective: This study evaluates the neuroprotective role of cedrol against lipopolysaccharide (LPS)-induced neuroinflammation and memory loss in rats. Methods Wistar rats were treated with cedrol (7.5, 15, and 30 mg/kg, oral, two weeks). During the last week, the rats (except for the control group) were treated with LPS (intraperitoneal injection, 1 mg/kg) to induce memory impairment. After that, the animals were subjected to behavioral studies (Morris water maze and passive avoidance) and biochemical assessments. Results Our results showed a significant decrease in learning and memory function-in LPS-induced rats which were reversed by cedrol. Also, there was a significant increase in the cerebral levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and malondialdehyde (MDA) as well as acetylcholinesterase (AChE) activity in LPS-treated rats. Besides, a significant reduction in total thiol and superoxide dismutase levels was observed in LPS-treated rats. However, cedrol significantly decreased the brain level of AChE, TNF-α, and IL-1β. Administration of cedrol also restored the oxidative stress markers. Conclusion the beneficial effects of cedrol against LPS-induced memory impairment could be due to antioxidant activities and modulation of neuro-inflammatory mediators.

Hibiscetin attenuates lipopolysaccharide-evoked memory impairment by inhibiting BDNF/caspase-3/NF-κB pathway in rodents. PeerJ 2024; 12:e16795. [PMID: 38313003 PMCID: PMC10838095 DOI: 10.7717/peerj.16795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 12/24/2023] [Indexed: 02/06/2024] Open
Abstract
This study explores the neuroprotective potential of hibiscetin concerning memory deficits induced by lipopolysaccharide (LPS) injection in rats. The aim of this study is to evaluate the effect of hibiscetin against LPS-injected memory deficits in rats. The behavioral paradigms were conducted to access LPS-induced memory deficits. Various biochemical parameters such as acetyl-cholinesterase activity, choline-acetyltransferase, antioxidant (superoxide dismutase, glutathione transferase, catalase), oxidative stress (malonaldehyde), and nitric oxide levels were examined. Furthermore, neuroinflammatory parameters such as tumor necrosis factor-α, interleukin-1β (IL-1β), IL-6, and nuclear factor-kappa B expression and brain-derived neurotrophic factor as well as apoptosis marker i.e., caspase-3 were evaluated. The results demonstrated that the hibiscetin-treated group exhibited significant recovery in LPS-induced memory deficits in rats by using behavioral paradigms, biochemical parameters, antioxidant levels, oxidative stress, neuroinflammatory markers, and apoptosis markers. Recent research suggested that hibiscetin may serve as a promising neuroprotective agent in experimental animals and could offer an alternative in LPS-injected memory deficits in rodent models.

Abstract
Objectives Human umbilical cord mesenchymal stem cells (HUC-MSCs) are pluripotent stem cells with anti-inflammatory and immunomodulatory properties used in the treatment of acute lung injury (ALI). However, the treatment of ALI using exosomes derived from HUC-MSCs (HUC-MSC-exos) primed with interferon-gamma (IFN-γ-exos) has not been described. This study investigated the effects of IFN-γ-exos on ALI. Materials and Methods IFN-γ primed and unprimed HUC-MSC-exos (IFN-γ-exos and CON-exos, respectively) were extracted, identified, and traced. A549 cells and mice subjected to lipopolysaccharide (LPS)-induced inflammation were treated with IFN-γ-exos or CON-exos. Viability; interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and reactive oxygen species (ROS) levels; NF-κB p65, and NLRP3 expression and histology and lung injury scores were measured in cell, supernatant or lung tissue. Results Indoleamine 2,3-dioxygenase (IDO) mRNA expression was elevated in HUC-MSCs primed with 5 ng/mL IFN-γ (P<0.001), and IFN-γ-exos and CON-exos were successfully extracted. LPS-induced inflammation resulted in decreased cell viability in A549 cells, and increased IL-1β, IL-6, TNF-α and ROS levels and NF-κB p65 and NLRP3 expression in A549 cells and mice(P<0.05 to P<0.001). Treatment with IFN-γ-exos and CON-exos increased cell viability and decreased the concentrations of IL-1β, and ROS, expression of NF-κB p65 and NLRP3, and the lung injury score, and these effects were more obvious for IFN-γ-exos(P<0.05 to P<0.001). Conclusion IFN-γ-exos reduced oxidative stress and inflammatory responses in LPS-induced A549 cells and mice. The result demonstrated the therapeutic potential of IFN-γ-exos in LPS-induced ALI.

[PMID: 37102170 PMCID: PMC10125742 DOI: 10.1155/2023/7675183] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/13/2022] [Accepted: 03/17/2023] [Indexed: 04/28/2023]
Abstract
Introduction Oxidative stress (OS) during inflammation can increase inflammatory responses and damage tissue. Lipopolysaccharide (LPS) can induce oxidative stress and inflammation in several organs. Natural products have several biological activities including anti-inflammatory, antioxidant, and immunoregulatory properties. The aims of the study are to study the possible therapeutic effects of natural products on LPS inducing toxicity on the nervous system, lung, liver, and immune system. Methods The in vitro and in vivo research articles that were published in the last 5 years were included in the current study. The keywords included "lipopolysaccharide," "toxicity," "natural products," and "plant extract" were searched in different databases such as Scopus, PubMed, and Google Scholar until October 2021. Results The results of most studies indicated that some medicinal herbs and their potent natural products can help to prevent, treat, and manage LPS-induced toxicity. Medicinal herbs and plant-derived natural products showed promising effects on managing and treating oxidative stress, inflammation, and immunomodulation by several mechanisms. Conclusion However, these findings provide information about natural products for the prevention and treatment of LPS-induced toxicity, but the scientific validation of natural products requires more evidence on animal models to replace modern commercial medicine.

Abstract
Goal of the current work was to conduct comparative analysis of the effects of acute and chronic lipopolysaccharide-induced stress on the behavior of rats in the Morris water maze test and on expression of mRNA of proinflammatory cytokines and BDNF in different brain structures. Relevance of this study is related to poor understanding of the effects of acute and chronic stress on manifestation of cognitive brain functions, as well as ambiguity of the literature data on the effects of both stresses on hypothalamic pituitary axis and expression of the proinflammatory cytokine genes. In the experiments with rats, acute lipopolysaccharide (LPS)-induced stress improved learning in the Morris water maze. For the period of learning, the rats under acute stress swam on average less distance to reach a hidden platform, spent less time in the peripheral zone of the pool (thigmotaxis), and had low speed compared to the control animals and to the group of rats under chronic LPS-induced stress. In the test without a platform in the pool there were no significant differences between the groups on the time spent in the platform quadrant and distance swum. Acute stress caused substantial increase of the TNF-α and IL-1β mRNA concentrations in the hippocampus and amygdala, but not in the frontal lobe in comparison with the control animals. Although chronic stress increased the levels of the TNF-α and IL-1β mRNA in the amygdala and hippocampus compared to the control groups, significance between the groups was only marginal and BDNF concentration did not differ from the control animals in any of the brain structures mentioned. Expression of the IL-6 mRNA only marginally increased in the amygdala of the animals under the acute LPS-induced stress and marginally decreased in the animals under chronic LPS stress in the hippocampus relative to the control groups. In total, the most pronounced molecular-biochemical changes occurred in the amygdala and hippocampus, where increase of the expression of the TNF-α and IL-1β interleukins mRNAs were observed in the animals under acute and chronic LPS-induced stress and no changes in the BDNF mRNA concentration were observed in the frontal lobe.
