In vitro defects of phagocyte chemotaxis during pregnancy.
Pregnant women have an increased risk for some infections, particularly during the last trimester. Phagocytic emigration from the circulation into tissues is an important aspect of the initial immune response. Therefore, circulating phagocytes of 42 pregnant and 15 postpartum patients were studied in vitro for random and chemotactic (or directional) migration through membrane filters (Millipore...
متن کاملModulating Phagocyte Activation
Helicobacter pylori (Hp) is a highly successful human pathogen that has colonized the gastric mucosa of approximately half of the world’s population. Infection with this gram-negative bacterium induces a state of chronic inflammation that does not resolve the underlying infection and often leads to gastric or duodenal ulcers or more rarely to gastric adenocarcinoma or mucosa-associated lymphoid...
متن کاملDefective Mononuclear Phagocyte Function
cytes may explain in part the frequency of infection and the mechanism of antibiotic-resistant infection in some patients with malignant myeloproliferative and lymphoproliferative diseases.
متن کاملAscorbate and phagocyte function.
Scorbutic guinea pig neutrophils (PMN) were found to produce H2O2 and kill Staphylococcus aureus as well as control PMN, suggesting that ascorbate does not contribute significantly to phagocyte H2O2 production or bacterial killing. Total and reduced ascorbate contents of human PMN was observed to fall upon phagocytosis, whereas dehydroascorbate increased to a lesser extent. These observations a...
متن کاملPhagocyte-bacteria interactions.
Recognition and phagocytosis of micro-organisms in a serum-poor environment represent innate immunity against many extracellular pathogens. As a paradigm for such processes, we discuss the recognition of Klebsiella pneumoniae by alveolar macrophages and monocyte-derived macrophages in the absence of serum. Macrophages recognize and subsequently kill Klebsiella expressing Man-alpha 2/3-Man or Rh...
