Targeted endothelial gene deletion of triggering receptor expressed on myeloid cells-1 protects mice during septic shock

ConclusionWe reported that TREM-1 is expressed and inducible in endothelial cells and plays a direct role in vascular inflammation and dysfunction. The targeted deletion of endothelialTrem-1 conferred protection during septic shock in modulating inflammatory cells mobilization and activation, restoring vasoreactivity, and improving survival. The effect of TREM-1 on vascular tone, while impressive, deserves further investigations including the design of endothelium-specific TREM-1 inhibitors.

We report a case of a 37-year-old previously healthy patient who presented to the emergency, four days after vaginal delivery, with abdominal pain and septic shock. Acute peritonitis was diagnosed and peritoneal and blood culture revealed group A streptococci. Unfortunately, the patient died within 12 hours despite adequate resuscitation and antimicrobials. The present case report highlights the importance of an early diagnosis with an adequate therapy in case of GAS peritonitis after vaginal delivery.

Toddalolactone (TA-8) is a main compound isolated from Toddalia asiatica (L.) Lam., and its anti-inflammatory activity and anti-inflammatory mechanism are less studied. In the present study, we investigated the anti-inflammatory effects of TA-8. Our experimental results showed that TA-8 inhibited the production of pro-inflammatory cytokines by both lipopolysaccharide (LPS)-activated RAW 264.7 cells and septic mice. Moreover, TA-8 suppressed the NF-κB transcriptional activity, reduced the nuclear translocation and phosphorylation of NF-κB, blocked the translocation of HMGB1 from the nucleus to cytosol, and decre...

Authors: Handke J, Piazza O, Larmann J, Tesoro S, De Robertis E Abstract Presepsin is the soluble fragment of CD14, a multifunctional glycoprotein expressed on the surface of innate immune cells. In healthy individuals, presepsin is present in very low concentrations with reference values ranging from 60 to 382 pg/ml. Several studies have shown that presepsin is a valuable biomarker for sepsis diagnosis in adults. Only lately, presepsin has been evaluated for prediction and early detection of neonatal sepsis and septic shock. Elevated plasma presepsin concentration has also been reported in patients undergoing card...

Streptococcus suis is an important porcine bacterial pathogen and zoonotic agent responsible for sudden death, septic shock, and meningitis. These pathologies are a consequence of elevated bacterial replication leading to exacerbated and uncontrolled inflammation, a hallmark of the S. suis systemic and central nervous system (CNS) infections. Monocytes and neutrophils are immune cells involved in various functions, including proinflammatory mediator production. Moreover, monocytes are composed of two main subsets: shorter-lived inflammatory monocytes and longer-lived patrolling monocytes. However, regardless of their prese...

CONCLUSION: The use of RGP prior to ureteral stent placement for an obstructing ureteral stone with concomitant UTI was not associated with unfavorable clinical outcomes in our retrospective series. While these findings support the safety of RGP in this setting, prospective trials are warranted. PMID: 32065871 [PubMed - in process]

Conclusions: FFPE tissue samples can be suitable for gene expression studies as well as immunostaining of specific cells or molecules. The most pronounced gene expression patterns were found in the organs with highest levels of Neisseria meningitidis DNA. Thousands of protein-coding and non-coding RNA transcripts were altered in lungs, heart and kidneys. We identified specific biomarker panels both protein-coding and non-coding RNA transcripts, which differed from organ to organ. Involvement of many genes and pathways add up and the combined effect induce organ failure.
