Analytical biochemistry, 587, 113445-113445 (2019-09-23)
Lipopolysaccharides (LPS) are the Gram-negative bacteria cell wall components capable to induce the system inflammatory response even at picomolar concentrations. LPS detection at these concentrations is necessary to develop new sorbents for the efficient purification of the biological fluids. LAL-test

Inflammasomes activate caspase-1 for processing and secretion of the cytokines interleukin-1beta (IL-1beta) and IL-18. Cryopyrin/NALP3/NLRP3 is an essential component of inflammasomes triggered by microbial ligands, danger-associated molecular patterns (DAMPs), and crystals. Inappropriate Cryopyrin activity has been incriminated in the pathogenesis

Phosphatidylserine (PS) exposure on the cell surface indicates apoptosis, but has also been related to evasion mechanisms of parasites, a concept known as apoptotic mimicry. Toxoplasma gondii mimics apoptotic cells by exposing PS, inducing secretion of TGF-beta1 by infected activated

Infection and immunity, 77(6), 2488-2498 (2009-04-01)
Parasitic worms and molecules derived from them have powerful anti-inflammatory properties and are shown to have therapeutic effects on inflammatory diseases. The helminth Fasciola hepatica has been reported to suppress antigen-specific Th1 responses in concurrent bacterial infections, thus demonstrating its

Pseudomonas aeruginosa can establish life-long airways chronic infection in patients with cystic fibrosis (CF) with pathogenic variants distinguished from initially acquired strain. Here, we analysed chemical and biological activity of P. aeruginosa Pathogen-Associated Molecular Patterns (PAMPs) in clonal strains, including

Using two-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis, we found that copper/zinc superoxide dismutase (Cu/Zn-SOD, SOD-1) was induced in constructed CCR5 stably transfected HEK 293 cells, but not in mock cells, treated with CCL5. CCL5-induced SOD-1 expression was also confirmed in

Intravascular-thrombosis and extravascular-lipid-deposit are the two key pathogenic events considered to interrupt intraosseous blood supply during development of steroid-associated osteonecrosis (ON). However, there are no clinically employed agents capable of simultaneously targeting these two key pathogenic events. The present experimental

Innate immunity, 18(6), 825-833 (2012-03-24)
Much evidence indicates that bacterial LPS (endotoxin) is removed from the bloodstream mainly by the liver, yet the hepatic uptake mechanisms remain uncertain and controversial. In plasma, LPS can be either 'free' (as aggregates, bacterial membrane fragments or loosely bound

The bee venom antimicrobial peptide, melittin, besides showing versatile activity against microorganisms also neutralizes lipopolysaccharide (LPS)-induced proinflammatory responses in macrophage cells. However, how the amino acid sequence of melittin contributes in its anti-inflammatory properties is mostly unknown. To determine the

Our previous work demonstrated that the extracellular matrix protein mindin contributes to allergic airways disease. However, the role of mindin in nonallergic airways disease has not previously been explored. We hypothesized that mindin would contribute to airways disease after inhalation
Shu Zhu et al.
Molecular medicine (Cambridge, Mass.), 15(7-8), 275-282 (2009-07-14)
The pathogenesis of sepsis is partly attributable to dysregulated inflammatory response mediated by pathogen-associated molecular patterns (PAMPs) (for example, endotoxin) and damage-associated molecular patterns (DAMPs) (for example, high-mobility group box 1 [HMGB1]). An endogenous ubiquitous polyamine, spermine, inhibits endotoxin-induced cytokine
Amit Kumar et al.
Scientific reports, 7, 39925-39925 (2017-01-05)
To become clinically effective, antimicrobial peptides (AMPs) should be non-cytotoxic to host cells. Piscidins are a group of fish-derived AMPs with potent antimicrobial and antiendotoxin activities but limited by extreme cytotoxicity. We conjectured that introduction of cationic residue(s) at the

Concomitant hepatocyte apoptosis and regeneration is a hallmark of chronic liver diseases (CLDs) predisposing to hepatocellular carcinoma (HCC). Here, we mechanistically link caspase-8-dependent apoptosis to HCC development via proliferation- and replication-associated DNA damage. Proliferation-associated replication stress, DNA damage, and genetic

American journal of respiratory and critical care medicine, 180(8), 720-730 (2009-08-08)
In humans, immune responses to inhaled aeroallergens develop in the lung and draining lymph nodes. Many animal models of asthma bypass this route and instead use intraperitoneal injections of allergen using aluminum hydroxide as an adjuvant. We investigated whether allergic

Epididymitis represents a serious threat to male fertility and usually develops following secondary bacterial infection of the epididymis such as urinary tract infections or sexually transmitted diseases. Surprisingly, very little is known about the innate host response triggered by bacterial
Hong Liu et al.
American journal of physiology. Heart and circulatory physiology, 319(6), H1482-H1495 (2020-10-17)
Multiple organ perfusion is impaired in sepsis. Clinical studies suggest that persistent perfusion disturbances are prognostic of fatal outcome in sepsis. Pyroptosis occurs upon activation of caspases and their subsequent cleavage of gasdermin D (Gsdmd), resulting in Gsdmd-N (activated NH2-terminal

Cell host & microbe, 6(6), 503-512 (2009-12-17)
Surviving infection represents a balance between the proinflammatory responses needed to eliminate the pathogen, and anti-inflammatory signals limiting damage to the host. IL-10 is a potent immunosuppressive cytokine whose impact is determined by the timing and localization of release. We
