The Role of CD44 in Concanavalin A-Induced Hepatitis
Administration of Concanavalin-A (Con A) induces severe injury to the hepatocytes in mice and is considered to be a model for human hepatitis. In the current study, we investigated the role of CD44 in Con A induced hepatitis. Although immune cells have been identified as the causative agent of Con …

Reciprocal Relationships Between the Neuroendocrine System and Lymphoid Cells
… that activation of porcine splenocytes with concanavalin A results in a two-fold increase in glucocorticoid and (beta)-adrenergic receptors with no change in the binding affinity of the receptor. Similarly, cortisol increases the number of (beta)-adrenoceptors on non-stimulated splenocytes. …

The Roles of Activin A and B in Liver Inflammation and Fibrosis
… investigated thoroughly. We treated mice with concanavalin A, a potent T-cell mitogen with liver specificity when administered intravenously, and characterized the resulting response to liver injury and how activin A and B are modulated during this acute inflammatory phase. We showed that …

Targeted nanoparticle platforms for selective photodynamic therapy of cancer
… of colorimetric techniques the interactions of Concanavalin A and succinyl-Concanavalin A with MCF-7 and SK-BR-3 human breast cancer cells expressing α-mannose was explored. The targeted PDT treatment of the breast cancer cells was attempted using C11Pc-PEG gold nanoparticles conjugated to …

The potential role of interleukin-2 in impaired cell-mediated immunity of iron deficiency
… parameters were measured in unstimulated and concanavalin A (Con A)-stimulated spleen lymphocytes from rats and mice. Dietary iron deficiency induced in the weanling Sprague-Dawley rat and C57/B16 mouse were used as the nutritional models.

A Possible Role For Prostaglandin E-B2-S as a Suppressor of Macrophage Phagocytosis
… treated with a low molecular weight fraction of Concanavalin A generated spleen cell culture supernatant. Suppressive activity of spleen cell culture supernatant was abrogated when supernatant was prepared in the presence of indomethacin, a prostaglandin synthetase inhibitor. These results …

A serological study of some cauliflower mosaic virus isolates
… glycosylated by the specific binding of labelled Concanavalin A. The role of carbohydrate residues in CaMV serological reactivity was evaluated.

Submicron Correlations Of Receptor-positions On Cell Surfaces
… performed on mouse fibroblasts with succinyl concanavalin A as receptor-ligand, determined that the succinyl concanavalin A binds with high affinity to numerous monomeric receptors and binds with low affinity to few large receptor clusters. The respective surface densities of these receptor …

Macrophage Suppression Across Genetic Barriers By a Spleen Cell Culture Derived Factor
Supernatant from Concanavalin A stimulated murine spleen cell cultures has been shown to contain a factor which suppresses in vitro phagocytosis of Listeria monocytogenes by resident murine peritoneal macrophages (PEC). The current investigation involved production of this macrophage suppressor …

Initial Characterization of Attachment of Infectious Pancreatic Necrosis Virus
… chymotrypsin, neuraminidase, protease, and concanavalin A (Con A) and the subsequent attachment of ³⁵S-methionine-labeled viruses assayed. IPN virus required 10 seconds to attach to CHSE cells. Significantly more viruses were adsorbed at 4°C than at 23°C or 30°C. Proteinases and …

Macrophage Suppression By a Low Molecular Weight Fraction of Murine Spleen Cell Culture Supernatant
… of this macrophage modulator (suppressor) by Concanavalin A-stimulated spleen cells. Spleen cell culture supernatant containing macrophage suppressor factor (MSF) caused a significant decrease in in vitro phagocytosis of Listeria monocytogenes by non-elicited peritoneal macrophages. The …

Spontaneous Rosette Formation In Mice Immunized With Listeria Monocytogenes
… to be significant by the Student's t test. Concanavalin A (Con A) binding studies were also performed to assess differences between lymphocyte surfaces in nonimmunized and immunized mice. It is suggested that depression of SRF in immunized mice is due to a surface modulation of the murine T …

Characterization of Attachment and Receptor Isolation of Infectious Pancreatic Necrosis Virus to Chse-214 Cells
… reduced attachment. Fewer viruses absorbed to Concanavalin A, lentil or fetuin treated cells, indicating the cellular receptor sites may contain a structural sialo-glycoprotein similar to glycophorin A. The IPNV receptor is suggested to reside in a coated pit covered by a masking protein, which …

Frazzled And Abelson Interact To Regulate The Actin Cytoskeleton In Drosophila
… in over 70% of the cells when plated on concanavalin A coated cover slips. These phalloidin stained filopodia are reduced when either the P1 or P3 cytoplasmic motif is removed. Frazzled is localized to the tips of these filopodia, and is associated with an increase in phosphotyrosine …
