OBJECTIVES Obesity prevalence among people living with HIV (HIV+) is rising. HIV and obesity are proinflammatory states, but their combined effect on inflammation (measured by interleukin 6, IL-6), altered coagulation (D-dimer), and monocyte activation (soluble CD14, sCD14) is unknown. We hypothesized inflammation increases when obesity and HIV infection co-occur. METHODS The Veterans Aging C...
The origin of soluble CD14 (sCD14) in the circulation is uncertain. To examine whether CD14 could be an acute-phase protein (APP), the levels of sCD14, IL-6, and C-reactive protein were determined by ELISA in serum and synovial fluid (SF) of patients with various arthropathies, and the regulation of CD14 synthesis was examined in liver cells. In patients with crystal-mediated or immunologically...
BACKGROUND Chronic immune activation is a feature of HIV infection associated with accelerated HIV disease progression. There is conflicting data on the association of biomarkers of immune activation with traditional markers of HIV disease progression; CD4 counts and viral load (VL). OBJECTIVE The study aimed to determine the association of biomarkers of immune activation; interferon (IFN)-γ-...
Lipopolysaccharide (LPS) is the principal stimulator of host defense against gram-negative bacteria. LPS-binding protein (LBP), bactericidal/permeability-increasing protein (BPI), and soluble CD14 (sCD14) bind LPS and regulate its toxicity. Lipoarabinomannan, a cell wall component of Mycobacterium tuberculosis, resembles LPS with respect to induction of inflammatory responses through recognitio...
Myeloid cell activation by lipopolysaccharides (LPS) involves two proteins, plasma LPS-binding protein (LBP) and cell-membrane CD14. Cell membrane CD14, anchored by a glycerophosphatidylinositol tail, is the cellular receptor for LPS-LBP complexes. Another form of CD14, without the lipid tail, circulates as a soluble plasma protein. In this work we show that soluble CD14 (sCD14) is required for...
Helicobacter pylori and Porphyromonas gingivalis are gram-negative bacteria associated with chronic inflammatory diseases. These bacteria possess lipopolysaccharides (LPSs) that are able to activate human monocytes to produce tumor necrosis factor alpha but fail to activate human endothelial cells to express E-selectin. With Escherichia coli LPS, tumor necrosis factor alpha activation requires ...
BACKGROUND HIV infection and biomarkers of inflammation [measured by interleukin-6 (IL-6)], monocyte activation [soluble CD14 (sCD14)], and coagulation (D-dimer) are associated with morbidity and mortality. We hypothesized that these immunologic processes mediate (explain) some of the excess risk of mortality among HIV infected (HIV+) versus uninfected people independently of comorbid diseases....
The soluble CD14 (sCD14) level was found associated with mortality during the chronic phase of human immunodeficiency virus (HIV) infection. Here we assessed its prognostic value in 138 patients with primary HIV infection. Higher sCD14 levels were associated with death, from myocardial infarction, but this was based on 3 deaths only. Among 68 untreated patients, those with higher sCD14 levels h...
Background: Early childhood caries (ECC) is a severe type of dental caries affecting infants and pre-school children. Because of the infectious nature of the disease, the immunologic response by the host plays an essential role in its development. Objective: This study investigated the association between the presence of salivary sCD14 and ECC. Methods: This study was carried out on 40 healthy ...
OBJECTIVES The changes in the serum levels of lipopolysaccharide binding protein (LBP) and sCD14 during cardiac surgery were followed in this study. DESIGN Thirty-four patients, 17 in each group, were randomly assigned to coronary artery bypass grafting surgery performed either with ("on-pump") or without ("off-pump") cardiopulmonary bypass. LBP and sCD14 were evaluated by ELISA. RESULTS Th...
