Effects of lipopolysaccharide on T lymphocyte cell subsets and cytokine secretion in Mesenteric lymph nodes of mice: histological and molecular study

Publication date: Available online 22 June 2019Source: Environmental Toxicology and PharmacologyAuthor(s): Chao Li, Hong-chao Zhou, Yi-Lin Nie, Bao-Yu Zhao, Chen-Chen WuAbstractLipololysaccharides (LPS) can disrupt the gut barrier. How dose LPS affects the immune performance of mesenteric lymph nodes? The results showed the hematological parameters significantly changed after LPS treatment. The length of intestinal villus was shortened and the depth of crypts was deepened, especially on the ileum. After LPS treatment 6 h, 12 h, the number of CD3+ T cells and CD4/CD8 in the mesenteric lymph nodes of ileum were reduced significantly; the levels of IFN-γ, TNF-ɑ and IL-2 were significantly decreased, and the levels of IL-6 and IL-10 were significantly increased in the ileum. The content of sIgA in the ileum was significantly decreased after LPS treatment 3 h, 6 h and was increased after LPS treatment 12 h. LPS through mesenteric lymph nodes, which induces the immune function reduced and the ileum injured obviously after treatment 6 h. Furthermore, the performance of intestinal immune performance was the lowest after LPS treatment 6 h.

CONCLUSION: Prevalence of antibiotic use was high not only versus other hospitals in the region but globally including Africa, coupled with significant evidence of sub-optimal prescribing. Swift action is needed to improve future prescribing to reduce AMR. One or two areas should initially be targeted for quality improvement including development of local guidelines, documentation of antibiotic indications and/or stop/review dates.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...

Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...
