The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

Enhanced myocardial glucose use in patients with a deficiency in long-chain fatty acid transport (CD36 deficiency). (1/1441)

CD36 is a multifunctional, 88 kDa glycoprotein that is expressed on platelets and monocytes/macrophages. CD36 also has high homology with the long-chain fatty acid (LFA) transporter in the myocardium. Although platelet and monocyte CD36 levels can indicate a CD36 deficiency, they cannot predict specific clinical manifestations in the myocardium of a given person. We examined the hypothesis that a deficiency in LFA transport augments myocardial glucose uptake in patients with a type I CD36 deficiency. METHODS: Seven fasting patients with a type I CD36 deficiency and 9 controls were assessed by cardiac radionuclide imaging using beta-methyl-p-iodophenyl-pentadecanoic acid (BMIPP) as a LFA tracer and by PET with 18F-fluorodeoxyglucose (FDG). RESULTS: None of the patients with a CD36 deficiency showed myocardial uptake of BMIPP. The percentage dose uptake of BMIPP in these subjects was significantly lower than that in normal controls (1.31+/-0.24 versus 2.90+/-0.2; P < 0.005). PET studies revealed that myocardial FDG accumulation was substantially increased in patients with a CD36 deficiency. Quantitative analysis showed that the percentage dose uptake of FDG in patients with a CD36 deficiency was significantly higher than that in normal controls (1.28+/-0.35 versus 0.43+/-0.22; P< 0.01). CONCLUSION: CD36 functions as a major myocardial LFA transporter and its absence may cause a compensatory upregulation of myocardial glucose uptake. (+info)

Role of class B scavenger receptor type I in phagocytosis of apoptotic rat spermatogenic cells by Sertoli cells. (2/1441)

Rat Sertoli cells phagocytose apoptotic spermatogenic cells, which consist mostly of spermatocytes, in primary culture by recognizing phosphatidylserine (PS) exposed on the surface of degenerating spermatogenic cells. We compared the mode of phagocytosis using spermatogenic cells at different stages of spermatogenesis. Spermatogenic cells were separated into several groups based on their ploidy, with purities of 60-90%. When the fractionated spermatogenic cell populations were subjected to a phagocytosis assay, cells with ploidies of 1n, 2n, and 4n were almost equally phagocytosed by Sertoli cells. All the cell populations exposed PS on the cell surface, and phagocytosis of all cell populations was similarly inhibited by the addition of PS-containing liposomes. Class B scavenger receptor type I (SR-BI), a candidate for the PS receptor, was detected in Sertoli cells. Overexpression of the rat SR-BI cDNA increased the PS-mediated phagocytic activity of Sertoli cell-derived cell lines. Moreover, phagocytosis of spermatogenic cells by Sertoli cells was inhibited in the presence of an anti-SR-BI antibody. Finally, the addition of high density lipoprotein, a ligand specific for SR-BI, decreased both phagocytosis of spermatogenic cells and incorporation of PS-containing liposomes by Sertoli cells. In conclusion, SR-BI functions at least partly as a PS receptor, enabling Sertoli cells to recognize and phagocytose apoptotic spermatogenic cells at all stages of differentiation. (+info)

Scavenger receptor BI (SR-BI) mediates free cholesterol flux independently of HDL tethering to the cell surface. (3/1441)

In addition to its effect on high density lipoprotein (HDL) cholesteryl ester (CE) uptake, scavenger receptor BI (SR-BI) was recently reported to stimulate free cholesterol (FC) flux from Chinese hamster ovary (CHO) cells stably expressing mouse SR-BI, a novel function of SR-BI that may play a role in cholesterol removal from the vessel wall where the receptor can be found. It is possible that SR-BI stimulates flux simply by tethering acceptor HDL particles in close apposition to the cell surface thereby facilitating the movement of cholesterol between the plasma membrane and HDL. To test this, we used transiently transfected cells and compared the closely related class B scavenger receptors mouse SR-BI and rat CD36 for their ability to stimulate cholesterol efflux as both receptors bind HDL with high affinity. The results showed that, although acceptor binding to SR-BI may contribute to efflux to a modest extent, the major stimulation of FC efflux occurs independently of acceptor binding to cell surface receptors. Instead our data indicate that SR-BI mediates alterations to membrane FC domains which provoke enhanced bidirectional FC flux between cells and extracellular acceptors. (+info)

Lower plasma levels and accelerated clearance of high density lipoprotein (HDL) and non-HDL cholesterol in scavenger receptor class B type I transgenic mice. (4/1441)

Recent studies have indicated that the scavenger receptor class B type I (SR-BI) may play an important role in the uptake of high density lipoprotein (HDL) cholesteryl ester in liver and steroidogenic tissues. To investigate the in vivo effects of liver-specific SR-BI overexpression on lipid metabolism, we created several lines of SR-BI transgenic mice with an SR-BI genomic construct where the SR-BI promoter region had been replaced by the apolipoprotein (apo)A-I promoter. The effect of constitutively increased SR-BI expression on plasma HDL and non-HDL lipoproteins and apolipoproteins was characterized. There was an inverse correlation between SR-BI expression and apoA-I and HDL cholesterol levels in transgenic mice fed either mouse chow or a diet high in fat and cholesterol. An unexpected finding in the SR-BI transgenic mice was the dramatic impact of the SR-BI transgene on non-HDL cholesterol and apoB whose levels were also inversely correlated with SR-BI expression. Consistent with the decrease in plasma HDL and non-HDL cholesterol was an accelerated clearance of HDL, non-HDL, and their major associated apolipoproteins in the transgenics compared with control animals. These in vivo studies of the effect of SR-BI overexpression on plasma lipoproteins support the previously proposed hypothesis that SR-BI accelerates the metabolism of HDL and also highlight the capacity of this receptor to participate in the metabolism of non-HDL lipoproteins.

Specific interaction of oxidized low-density lipoprotein with macrophage-derived foam cells isolated from rabbit atherosclerotic lesions. (5/1441)

Interaction of oxidized LDL (OxLDL) with macrophage-derived foam cells is one of the key events in the development and progression of atherosclerosis. To study this interaction, macrophage-derived foam cells were isolated from rabbit atherosclerotic lesions and the expression of scavenger receptors for OxLDL was examined. Atherosclerosis was induced in rabbits by denudation of the large arteries, followed by a hypercholesteremic diet. Macrophage-derived foam cells, characterized by immunostaining with an RAM-11 antibody (a macrophage marker), contained a high content of intracellular lipid. Maximal binding of radiolabeled OxLDL to isolated macrophage-derived foam cells (1652+/-235 ng 125I-OxLDL/mg of cell protein) was 20-fold higher compared with Bmax values of monocytes. Levels of association of OxLDL to macrophage-derived foam cells isolated from atherosclerotic lesions 12 weeks after denudation were >3-fold higher compared with the levels expressed by macrophage-derived foam cells isolated after 6 weeks. Association of 125I-OxLDL could be completely blocked by OxLDL, and partially by acetylated LDL and polyinosinic acid, indicating the presence of a specific binding site for OxLDL on macrophage-derived foam cells. The induction of scavenger receptors for OxLDL on macrophage-derived foam cells during the development of atherosclerosis, as described in this study, may facilitate the lipid accumulation in macrophage-derived foam cells, as observed in advanced atherosclerotic lesions.

Scavenger receptor BI mediates the selective uptake of oxidized cholesterol esters by rat liver. (6/1441)

High density lipoprotein (HDL) can protect low density lipoprotein (LDL) against oxidation. Oxidized cholesterol esters from LDL can be transferred to HDL and efficiently and selectively removed from the blood circulation by the liver and adrenal in vivo. In the present study, we investigated whether scavenger receptor BI (SR-BI) is responsible for this process. At 30 min after injection, the selective uptake of oxidized cholesterol esters from HDL for liver and adrenal was 2.3- and 2.6-fold higher, respectively, than for native cholesterol esters, whereas other tissues showed no significant difference. The selective uptake of oxidized cholesterol esters from HDL by isolated liver parenchymal cells could be blocked for 75% by oxidized LDL and for 50% by phosphatidylserine liposomes, both of which are known substrates of SR-BI. In vivo uptake of oxidized cholesterol esters from HDL by parenchymal cells decreased by 64 and 81% when rats were treated with estradiol and a high cholesterol diet, respectively, whereas Kupffer cells showed 660 and 475% increases, respectively. These contrasting changes in oxidized cholesterol ester uptake were accompanied by similar contrasting changes in SR-BI expression of parenchymal and Kupffer cells. The rates of SR-BI-mediated selective uptake of oxidized and native cholesterol esters were analyzed in SR-BI-transfected Chinese hamster ovary cells. SR-BI-mediated selective uptake was 3.4-fold higher for oxidized than for native cholesterol esters (30 min of incubation). It is concluded that in addition to the selective uptake of native cholesterol esters, SR-BI is responsible for the highly efficient selective uptake of oxidized cholesterol esters from HDL and thus forms an essential mediator in the HDL-associated protection system for atherogenic oxidized cholesterol esters.

Selection-dominant and nonaccessible epitopes on cell-surface receptors revealed by cell-panning with a large phage antibody library. (7/1441)

To generate antibodies to defined cell-surface antigens, we used a large phage antibody fragment library to select on cell transfectants expressing one of three chosen receptors. First, in vitro panning procedures and phage antibody screening ELISAs were developed using whole live cells stably expressing the antigen of interest. When these methodologies were applied to Chinese hamster ovary (CHO) cells expressing one of the receptors for a neuropeptide, somatostatin, using either direct cell panning or a strategy of depletion or ligand-directed elution, many different pan-CHO-cell binders were selected, but none was receptor specific. However, when using direct panning on CHO-cells expressing the human membrane protein CD36, an extraordinary high frequency of antigen-specific phage antibodies was found. Panning on myoblasts expressing the rat homologue of CD36 revealed a similar selection dominance for anti-(CD36). Binding of all selected 20 different anti-(CD36) phage was surprisingly inhibited by one anti-(CD36) mAb CLB-IVC7, which recognizes a functional epitope that is also immunodominant in vivo. Similar inhibition was found for seven anti-(rat) CD36 that cross-reacted with human CD36. Our results show that, although cells can be used as antigen carriers to select and screen phage antibodies, the nature of the antigen target has a profound effect on the outcome of the selection.

Uptake and fate of class B scavenger receptor ligands in HepG2 cells. (8/1441)

Class B scavenger receptors (SR-Bs) interact with native, acetylated and oxidized low-density lipoprotein (LDL, AcLDL and OxLDL), high-density lipoprotein (HDL3) and maleylated BSA (M-BSA). The aim of this study was to analyze the catabolism of CD36- and LIMPII-analogous-1 (CLA-1), the human orthologue for the scavenger receptor class B type I (SR-BI), and CD36 ligands in HepG2 (human hepatoma) cells. Saturation binding experiments revealed moderate-affinity binding sites for all the SR-B ligands tested with dissociation constants ranging from 20 to 30 microg.mL-1. Competition binding studies at 4 degrees C showed that HDL and modified and native LDL share common binding site(s), as OxLDL competed for the binding of 125I-LDL and 125I-HDL3 and vice versa, and that only M-BSA and LDL may have distinct binding sites. Degradation/association ratios for SR-B ligands show that LDL is very efficiently degraded, while M-BSA and HDL3 are poorly degraded. The modified LDL degradation/association ratio is equivalent to 60% of the LDL degradation ratio, but is three times higher than that of HDL3. All lipoproteins were good cholesteryl ester (CE) donors to HepG2 cells, as a 3.6-4.7-fold CE-selective uptake ([3H]CE association/125I-protein association) was measured. M-BSA efficiently competed for the CE-selective uptake of LDL-, OxLDL-, AcLDL- and HDL3-CE. All other lipoproteins tested were also good competitors with some minor variations. Hydrolysis of [3H]CE-lipoproteins in the presence of chloroquine demonstrated that modified and native LDL-CE were mainly hydrolyzed in lysosomes, whereas HDL3-CE was hydrolyzed in both lysosomal and extralysosomal compartments. Inhibition of the selective uptake of CE from HDL and native modified LDL by SR-B ligands clearly suggests that CLA-1 and/or CD36 are involved at least partially in this process in HepG2 cells.
