To investigate the effects of the estrogen receptor-binding molecule bisphenol A (BPA) on murine immune function in vivo, we fed a low dose of 2.5 micro g BPA/kg body weight/day to both normal C57BL/6 and lupus-prone NZB X NZW F(1) (NZB/NZW) 5-week-old mice for 1 week. Analysis of concanavalin A (ConA)-stimulated splenic mononuclear cells by ELISA demonstrated that BPA-fed C57BL/6 males produce...
Halofuginone (HF) is an active component of extracts derived from the plant alkaloid febrifugine and has shown therapeutic promise in animal models of fibrotic disease. Our main objectives were to clarify the suppressive effect of HF on concanavalin A (ConA)-induced liver fibrosis. ConA injection into the tail vein caused a great increase in the serum aspartate aminotransferase (AST) and alanin...
Cyclodextrin vesicles are versatile models for biological cell membranes since they provide a bilayer membrane that can easily be modified by host-guest interactions with functional guest molecules. In this article, we investigate the multivalent interaction of the lectin concanavalin A (ConA) with cyclodextrin vesicles decorated with mannose-adamantane conjugates with one, two or three adamant...
This study was designed to study the protective effects and mechanisms of N-acetylcysteine (NAC) in concanavalin A-induced hepatitis in mice. In this study, pretreatment with NAC ameliorated the histopathological changes and suppressed inflammatory cytokines in ConA-induced hepatitis. The expression of IL-2, IL-6, TNF-α, and IFN-γ was significantly reduced in the NAC-treated groups. NAC activat...
We developed an assay for the direct determination of selenium in serum with a Perkin-Elmer Model 4100ZL Zeeman atomic absorption spectrometer and Ag-Cu-Mg modifier. We used this assay to analyze concanavalin A-bound selenoprotein (CABSP) in human serum after concanavalin A (ConA) affinity chromatography. The CABSP was identified as a single-chain glycoprotein of 57.3 kDa. Carbohydrate units we...
The extracellular matrix molecules tenascin, laminin, and fibronectin, the cell adhesion molecule L1, and the lectin concanavalin A (ConA) were tested for their effects on neuritogenesis in cultures of hippocampal neurons. We analyzed neurite outgrowth between 3 and 21 hr after plating and found that, on polyornithine as control substrate, lengths of axon-like major neurites and dendrite-like m...
In this study, we investigated the expression of activated gelatinase A and membrane-type metalloproteinase (MT-MMP) induced by concanavalin A (ConA) in four highly invasive glioma cell lines (UWR2, UWR3, U251MG, and SNB-19). We also examined gelatinase A and MT-MMP expression in human brain tumor tissues in vivo. Gelatin zymography showed that all four cell lines expressed latent progelatinase...
There is controversy in the literature over whether the selenium (Se) influences cellular immune responses, and the mechanisms possibly underlying these effects are unclear. In this study, the effects of Se on T-cell proliferation and IL-2 production were studied in primary porcine splenocytes. Splenocytes were treated with different mitogens in the presence of 0.5-4 µmol/L sodium selenite. Se ...
Xyloglucan and Concanavalin A based dressings in the topical treatment of mice wound healing process
For medical biomaterials, xyloglucan dispersions can form films or gels to be applied as a wound dressing. this purpose, the structural characterization of dressing (XG) and containing 0.5 mg/mL concanavalin A (XGL) was performed. The lectin release capacity stability, cytotoxicity, pro-wound healing effects were also investigated. XG XGL prepared by mixing % (w/v) with 0.3 (v/v) glycerol. ConA...
