Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 7, 2024

Abstract Sepsis-induced cardiac injury represents a major clinical challenge, amplifying the urgency for effective therapeutic interventions. This study aimed to delve into individual and combined prophylactic effects of Vitamin C (Vit C) Coenzyme Q10 (CoQ10) against inflammatory heart in cecal ligation puncture (CLP) induced polymicrobial sepsis rat model. Thirty adult female Sprague–Dawley rats were randomly divided five groups: Control, CLP, C, CoQ10, Vit + each consisting six rats. Treatments administered orally via gavage 10 days prior operation. Eighteen hours post-sepsis induction, animals euthanized, specimens collected analysis. The examined variations oxidative (TOS, OSI, MDA, MPO) antioxidative markers (TAS, SOD, CAT, GSH), histopathological changes, cytokine concentrations (TNF-α, IL-1β), nitric oxide (NO) dynamics, indicators such as CK-MB. Impressively, regimen markedly diminished stress, parameters reflected notable enhancements. Elevated NO levels, central player sepsis-driven cascades, effectively tempered by our intervention. Histological examinations corroborated biochemical data, revealing tissue damage treated subjects. Furthermore, marked suppression pro-inflammatory cytokines was discerned, solidifying potential Interestingly, certain evaluations, CoQ10 exhibited superior benefits over C. Collectively, these findings underscore promise combination septic injuries

Опубликована: Март 28, 2024

Sepsis is a life-threatening condition characterized by systemic inflammatory response to infection. Despite extensive research on its pathophysiology, effective therapeutic approaches remain challenge. This study investigated the potential of resveratrol (RV) and silver nanoparticle-enhanced (AgNP-RV) as treatments for sepsis-induced lung injury using rat model polymicrobial sepsis induced cecal ligation puncture (CLP). The focused evaluating changes in oxidative status (TAS, TOS, OSI) expression apoptotic markers (IL-1β, TNF-α, P2X7R, TLR4, Caspase-3, Bcl-2) tissue. Both RV AgNP-RV demonstrated mitigating stress, inflammation, apoptosis, with exhibiting greater efficacy than alone (p < 0.05). These findings were corroborated histopathological analyses, which revealed reduced tissue damage RV- AgNP-RV-treated groups. Our highlights and, particularly, combating apoptosis. It also underscores promise nanoparticle technology enhancing outcomes. However, further investigations are warranted fully understand mechanisms action, especially concerning role P2X7 receptor observed effects. Nonetheless, our suggests that hold novel strategies management.

The role and therapeutic potential of SIRTs in sepsis

Frontiers in Immunology, Год журнала: 2024, Номер 15

Опубликована: Апрель 16, 2024

Sepsis is a life-threatening organ dysfunction caused by the host’s dysfunctional response to infection. Abnormal activation of immune system and disturbance energy metabolism play key role in development sepsis. In recent years, Sirtuins (SIRTs) family has been found an important pathogenesis SIRTs, as class histone deacetylases (HDACs), are widely involved cellular inflammation regulation, oxidative stress. The effects SIRTs on cells mainly reflected regulation inflammatory pathways. This helps balance may lessen cell damage terms metabolism, can immunophenotypic transformation regulating improve mitochondrial function, increase production, maintain balance. also regulate production reactive oxygen species (ROS), protecting from stress activating antioxidant defense pathways maintaining between oxidants reducing agents. Current studies have shown that several potential drugs, such Resveratrol melatonin, enhance activity SIRT. It help reduce response, stress, showing clinical application prospects for treatment review focuses SIRT cells, well its influence multiple sepsis, discusses summarizes related drugs compounds sepsis through pathway involving SIRTs. become new target resulting dysfunction, providing ideas possibilities this disease.

ABSTRACT Sepsis-induced acute liver injury is a life-threatening condition involving inflammation, oxidative stress, and endothelial dysfunction. In the present study, preventive effects of resveratrol (RV) alone resveratrol-loaded silver nanoparticles (AgNPs+RV) against sepsis-induced damage were investigated compared in rat model polymicrobial sepsis induced by cecal ligation puncture (CLP). Rats divided into four groups: Sham, CLP, RV, AgNPs+RV. Pro-inflammatory cytokines (tumor necrosis factor-alpha [TNF-α], interleukin-1 beta [IL-1β], interleukin-6 [IL-6]), nuclear factor kappa-light-chain-enhancer activated B cells (NF-κB) activation, presepsin, procalcitonin, 8-hydroxy-2'-deoxyguanosine (8-OHDG), vascular growth (VEGF), Sirtuin-1 (SIRT-1) levels assessed to determine treatments' effects. AgNPs+RV treatment significantly reduced pro-inflammatory cytokines, NF-κB 8-OHDG, VEGF CLP group, indicating attenuation injury. Both RV treatments increased SIRT1 levels, suggesting potential role activation mediating protective conclusion, demonstrated extremely enhanced efficacy alleviating modulating dysfunction, potentially mediated through activation. this effect on was evaluated for first time these findings highlight as promising therapeutic strategy managing injury, warranting further investigation.

Abstract Acute lung injury (ALI) is a severe respiratory disorder associated with high morbidity and mortality. Lipopolysaccharide (LPS) widely used to induce ALI in animal models. D-carvone, natural monoterpene, has been reported possess anti-inflammatory antioxidant properties. This study aimed investigate the protective effects of D-carvone on LPS-induced rats. Thirty-six male rats were randomly divided into six groups ( n = 6): control, (10 mg/kg 20 p.o.), LPS E. coli lipopolysaccharide i.p.), + (LPS either 10 or D-carvone). was administered orally once daily for days. On day 10, sepsis induced administration, samples collected after 6 h under deep anesthesia. administration caused significant injury, as evidenced by increased histopathological scores, upregulation pro-inflammatory markers (TLR4, IL-1β, TNF-α), oxidative stress (increased MDA, decreased GSH SOD). Treatment at both doses significantly attenuated these changes. downregulated markers, upregulated (NRF2) anti-apoptotic (Bcl-2) proteins, reduced levels cytokines (IL-1β, TNF-α, IL-8) tissues.

Acute kidney injury (AKI) is one of the most serious complications sepsis, with substantial morbidity and mortality, no effective treatment exists. Ebselen pharmacological significance in prevention a variety human diseases, such as cancer cardiovascular disorders. Nevertheless, role pathogenesis sepsis-induced AKI remains unknown. Therefore, we aimed to elucidate impact Ebselen, an active seleno-organic compound, on induced by lipopolysaccharide (LPS) associated molecular mechanisms, including endoplasmic reticulum (ER) stress, apoptosis, oxidative stress. We established rat model injecting 5 mg/kg LPS intraperitoneally. The rats were given (5 10 mg/kg, orally) before receiving injection. alleviated renal tubular reduced levels blood urea nitrogen (BUN) creatinine (CREA) LPS-induced sepsis model. Immunohistochemical terminal deoxynucleotidyl transferase dUTP nick end labelling (TUNEL) analyses revealed that caspase-3 expressions apoptotic cells triggered tissues. caused ER stress regulating eukaryotic translation initiation factor 2-alpha kinase 3 (EIF2AK3) GRP78 tissue, well activating transcription 4 (ATF4) 6 (ATF6) serum. decreased malondialdehyde (MDA) LPS. modulating MDA superoxide dismutase (SOD) tissues SOD, glutathione peroxidase (GPx) serum total antioxidant status (TAS) In conclusion, report for time might alleviate through regulation apoptosis
