Granulocyte-macrophage colony-stimulating activity (GM-CSA) can be produced by a variety of normal cell types including mononuclear phagocytes, activated T lymphocytes, endothelial cells, and fibroblasts. Recent evidence shows that a major role of the monocyte-macrophage is the recruitment of environmental cells, i.e., fibroblasts, to produce GM-CSA. In this study we have identified interleukin...
Monocyte recruitment and differentiation into dendritic cells or macrophages play a critical role in defense mechanisms against pathogens and in inflammatory and autoimmune diseases. Important contributions have been made on the molecular events controlling neutrophil and lymphocyte extravasation under steady state or inflammation. However, the molecules involved in monocyte rolling during thei...
Oxidatively modified low-density lipoprotein (oxLDL) plays a key role in the initiation of atherosclerosis by increasing monocyte adhesion. The mechanism that is responsible for the oxLDL-induced atherogenic monocyte recruitment in vivo, however, still remains unknown. Oxidation of LDL generates lysophosphatidylcholine, which is the main substrate for the lysophosphatidic acid (LPA) generating ...
It is widely accepted that destruction of CD4(+) T cells and viral load are the primary markers for immunodeficiency in HIV-1-infected humans and in simian immunodeficiency virus (SIV)-infected macaques. However, monocyte/macrophages are also important targets of HIV/SIV infection and a critical link between innate and adaptive immunity. We therefore examined whether changes in cells of the mon...
Cerebral malaria continues to be a difficult to treat complication of Plasmodium falciparum infection in children. We have shown that platelets can have major deleterious immune functions in experimental cerebral malaria (ECM). One of the platelet derived mediators we have identified as particularly important is platelet factor 4/CXCL4. Our prior work demonstrated that PF4(-/-) mice are protect...
We investigated the interaction of monocyte/macrophages and autologous T lymphocytes in the methanol extraction residue (MER) of BCG-induced production of granulocyte-macrophage colony-stimulating activity (CSA). Coincubation of monocyte/macrophages and T lymphocytes at a 1 :3 ratio produces an optimum collaboration; a change to a 1 :9 ratio diminished this collaboration. Coincubation of monocy...
