Effects of repeated lipopolysaccharide treatment on growth performance, immune organ index, and blood parameters of Sprague-Dawley rats

Introduction Immune challenge is regarded as a major obstacle to achieving the animal’s genetic potential for growth or to efficiency of weight gain ( 21 ). Lipopolysaccharide (LPS), an important component of Gram-negative bacterium cytoderm ( 18 ), can be used as a stressor to activate the immune system ( 4 ). The acyl is inlaid into the outer membrane of bacteria, and the sugar chains are exposed to the outer surface of bacteria ( 9 ). Thus, LPS has strong antigen-specificity and can be recognised by antigen-presenting cells. LPS can induce inflammation and

Exposure to a single immobilization or lipopolysaccharide challenge increases expression of genes implicated in the development of Alzheimer’s disease in the mice brain cortex

Abstract

Objectives. Despite extensive research efforts, mechanisms participating on development of Alzheimer’s disease (AD) are covered only partially. Data from the last decades indicate that various stressors, as etiological factors, may play a role of in the AD. Therefore, we investigated the effect of two acute stressors, immobilization (IMO) and lipopolysaccharide (LPS), on the AD-related neuropathology.

Methods. Adult C57BL/6J mice males were exposed to a single IMO stress or a single intraperitoneal injection of LPS (250 µg/kg body weight). After terminating the experiments, the brains were removed and their cortices isolated. Gene expression of pro-inflammatory cytokines, as well as expression of genes implicated in the AD neuropathology were determined. In addition, mediators related to the activation of the microglia, monocytes, and perivascular macrophages were determined in brain cortices, as well.

Results. In comparison with the control animals, we found increased gene expression of proinflammatory mediators in mice brain cortex in both IMO and LPS groups. In stressed animals, we also showed an increased expression of genes related to the AD neuropathology, as well as positive correlations between genes implicated in AD development and associated neuroinflammation.

Conclusions. Our data indicate that acute exposure to a strong IMO stressor, composed of the combined physical and psychological challenges, induces similar inflammatory and other ADrelated neuropathological changes as the immune LPS treatment. Our data also indicate that cytokines are most likely released from the peripheral immune cells, as we detected myeloid cells activity, without any microglia response. We hypothesize that stress induces innate immune response in the brain that consequently potentiate the expression of genes implicated in the AD-related neuropathology.

Effects of polymyxin B on clinical signs, serum TNF-α, haptoglobin and plasma lactate concentrations in experimental endotoxaemia in sheep

. Lipopolysaccharides (LPS), also known as endotoxins, are an integral part of the outer membrane of the cell wall in Gram-negative bacteria ( 28 ). LPS stimulate many adverse systemic reactions and trigger the release of pro-inflammatory mediators ( 27 , 32 ). Over the past years, several therapeutic strategies have been designed for treatment and prevention of endotoxaemia. Therapies suggested for Gram-negative sepsis and septic shock involve utilisation of antibiotics to control the infection and intensive care support to correct the underlying dysfunctions in circulatory
