To define the phenotype and location of antigen-presenting cells (APCs) in normal donor human corneas, and to assess the response of APC to herpes simplex virus type 1 (HSV-1) infection.Donor human corneal tissue was analyzed by fluorescence confocal microscopy and flow cytometry to determine ...
As phagocytosis by macrophages plays a critical role in the control of bacteria, we investigated the phagocytic activity of macrophages after resolution of inflammation. After resolution of primary pneumonia, murine alveolar macrophages (AMs) exhibited poor phagocytic capacity for several weeks. These ...
Expression of α7 nicotinic acetylcholine receptors (nAChRs) on antigen presenting cells (APCs), such as macrophages and dendritic cells, is now well established. We have shown that GTS-21, a selective α7 nAChR agonist, downregulates APC-dependent CD4+ T cell differentiation into regulatory T ce...
Nikolic T, Geutskens SB, van Rooijen N, Drexhage HA, Leenen PJ: Dendritic cells and macrophages are essential for the retention of lymphocytes in (peri)-insulitis of the nonobese diabetic mouse: a phagocyte depletion study. Lab Invest 85:487-501, 2005...
Antigen presenting cells:Antigens are either foreign substances or human cell surfaces that are unique in each individual, except for identical twins. They are usually composed of complex proteins or polysaccharides, or can be composed of glycoproteins. Antigens activate the immune system to produce ...
Aortic resident macrophages expand in situ via direct cell renewal. Induced depletion of intimal macrophages leads to thrombin-mediated endothelial cell contraction, progressive fibrin accumulation and formation of microthrombi that, once dislodged, cause blockade of vessels in several organs. Together the...
aDuring the development of T1D, islet autoantigens are displayed at the surface of antigen presenting cells (APCs) such as dendritic cells (DCs) and macrophages inducing a cytotoxic T cell response. 在T1D的发展期间,小岛autoantigens被显示在提出细胞APCs例如树状 (细胞) DCs和巨噬细胞的 (抗原) ...
Subclustering of immune cells resulted in eight immune cell clusters, including T and B cells, granulocytes, and antigen-presenting cells (Figs.2DandS2C). Interestingly, CD4 and CD8 T cells from healthy samples (hTcells) formed a distinct cluster, adjacent to CD4 (tCD4) and CD8 T cells (...
[149]. UFH also binds to endothelial cells, macrophages, platelets and multiple plasma proteins besides AT including von Willebrand factor, lipoproteins and fibrinogen, which limits the anticoagulant potency of UFH and increases the variability in response to UFH [144,150]. Although use of UFH has...
