BACKGROUND
The potential edematogenic effect and the pharmacological characterization of a glucose-mannose-binding lectin from Dioclea violacea (DvL) were investigated.
METHODS
Paw edema was induced with DvL in control animals, and in animals pretreated with glucocorticoid or with blockers of
Lectins from Dioclea grandiflora (DG) and Canavalia brasiliensis (CB) were compared with Concanavalin A (ConA) for their ability to induce paw edema and peritoneal cell immigration in rats. ConA caused a slight edema with a peak at 1 h after injection, while DG or CB induced a pronounced and
Recent studies have shown that lectins are promising tools for use in various biotechnological processes, as well as studies of various pathological mechanisms, isolation, and characterization of glycoconjugates and understanding the mechanisms underlying pathological mechanisms conditions,
OBJECTIVE
Neutrophils are implicated in the physiopathologic alterations of hemorrhagic cystitis (HC). Thus, we decided to test the antiinflammatory activity of glucose-mannose binding lectins extracted from D. violacea and D. guianensis seeds, which showed an inhibitory effect upon neutrophil
A novel lectin present in Dioclea reflexa seeds (DrfL) was discovered and described in this study. DrfL was purified in a single step by affinity chromatography in a Sephadex G-50 column. The lectin strongly agglutinated rabbit erythrocytes and was inhibited by α-methyl-D-mannoside, D-mannose, and
Lectins are proteins, or glycoproteins, capable of reversibly binding to specific mono- or oligosaccharides via a noncatalytic domain. The Diocleinae subtribe presents lectins with high structural similarity, but different effects based on biological activity assays. This variability results from
With important carbohydrate binding properties, lectins are proteins able to decipher the glycocode, and as such, they can be used in bioassays involving cell-cell communication, protein targeting, inflammation, and hypernociception, among others. In this study, a new glucose/mannose-specific lectin
