CD14 is a high-affinity receptor protein for the complex of bacterial LPS (LPS) and LPS binding protein in animals. Binding of the soluble form of CD14 (sCD14) to LPS, found in the outer membrane of Escherichia coli and other Gram-negative bacteria, enhances host innate immune responses, reduces the severity of mastitis, and facilitates clearance and neutralization of LPS, thus protecting again...

BACKGROUND One in four cystic fibrosis (CF) patients diagnosed with a pulmonary exacerbation will not recover their baseline lung function despite standard treatment. This highlights the importance of preventing such events. Clinical decision-making can be improved through a simple blood test that predicts individuals at elevated short-term risk of an exacerbation. METHODS We obtained plasma ...

Abstract Introduction Although regular physical activity is associated with reduced risk of cardiovascular disease (CVD), acute vigorous exercise seems to transiently increase the coronary events in patients underlying CVD. Some studies have reported associate microbial diversity, whereas elevated levels gut leakage markers been shown after strenuous healthy individuals. Any predictive value a ...

Allergic asthma is associated with the recruitment of activated inflammatory cells after allergen challenge. Surface expression of CD14 has been proposed as a marker of cell activation and differentiation. We therefore measured CD14 expression on activated macrophages and granulocytes as well as soluble CD14 (sCD14) concentrations in peripheral blood and bronchoalveolar lavage (BAL) following s...

CD14 is a pattern recognition receptor involved in the interaction with multiple ligands, including LPS from gram-negative bacteria and lipoarabinomannan (LAM) from mycobacteria. While the interactions between LPS and soluble CD14 (sCD14) have been analyzed in detail, LAM/CD14 interactions remain uncharacterized due to the lack of suitable functional assays. We describe herein a novel bioassay ...

INTRODUCTION Chronic obstructive pulmonary disease (COPD) has been recently defined as a systemic pulmonary inflammatory disease, and congenital α1 antitrypsin deficiency is one of the well-established genetic risk factors for chronic obstructive pulmonary disease. The aim of our study was to evaluate the possible associations of α1 antitrypsin with inflammatory markers - CRP, sCD14, TNF-α, sTN...

BACKGROUND Bacterial translocation (BT) commonly occurs in cirrhosis. Reliable biomarkers for BT are currently lacking. Human beta defensin-1 (hBD-1) is a member of the family of natural antimicrobial peptides produced by epithelial cells and participates in the mucosal defensive mechanisms that prevent BT. The aim of the present study was to examine the local and systemic expression of hBD-1 i...

Macrophages, neutrophils and infection have been implicated in the genesis of the bronchiolitis obliterans syndrome (BOS) post lung transplantation. sCD14 is a soluble form of a shed-cell surface protein. It is capable of promoting cytokine-induced inflammation and it's presence in clinically stable lung transplant recipients (LTR) might be important as an early marker of BOS. Bronchalveolar la...

BACKGROUND Microbial translocation has been implicated in the pathogenesis of liver fibrosis and cirrhosis. We sought to determine whether markers of microbial translocation are associated with liver disease progression during coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). METHODS We measured serial plasma lipopolysaccharide (LPS), endotoxin core antibody, in...

Background/Aim. Despite the widespread use of procalcitonin, C-reactive protein (CRP), and soluble CD14 subtype (sCD14-ST), their diagnostic accuracy in children with sepsis is not yet clear. The aim study was to establish compare CRP, sCD14-ST admitted hospital under suspicion having sepsis. Methods. designed as a retrospective cross-sectional on Pediatrics Clinic Kragujevac, Serbia, sepsis, d...
