Inflammatory cutaneous reaction induced by the lectin of Dioclea grandiflora (Mart.).

Numai utilizatorii înregistrați pot traduce articole

The lectin from Dioclea grandiflora (Mart.) that selectively binds glucose and mannose, when subcutaneously injected in mouse induces an inflammatory cutaneous reaction whose histological analysis reveals an hemorrhagic ulceration with exudative reaction accompanied by an influx of polymorphonuclear

Purification and molecular characterization of a novel mannose-specific lectin from Dioclea reflexa hook seeds with inflammatory activity.

Numai utilizatorii înregistrați pot traduce articole

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

Dioclea violacea lectin ameliorates inflammation in the temporomandibular joint of rats by suppressing intercellular adhesion molecule-1 expression.

Numai utilizatorii înregistrați pot traduce articole

Inflammation of temporomandibular joint (TMJ) tissues are the most common cause of pain conditions associated with temporomandibular disorders (TMDs). After a tissue and/or neural damage, the inflammatory response is characterized by plasma extravasation and leukocytes infiltration in the TMJ

Crystal structure of a pro-inflammatory lectin from the seeds of Dioclea wilsonii Standl.

Numai utilizatorii înregistrați pot traduce articole

The crystal structure and pro-inflammatory property of a lectin from the seeds of Dioclea wilsonii (DwL) were analyzed to gain a better understanding of structure/function relationships of Diocleinae lectins. Following crystallization and structural determination by standard molecular replacement

Anti-inflammatory effect of glucose-mannose binding lectins isolated from Brazilian beans.

Numai utilizatorii înregistrați pot traduce articole

Selectins are essential for leukocyte recruitment in inflammation. Because of a lectin domain present in the selectin structure, we investigated the anti-inflammtory activity of six mannose-glucose binding lectins from brazilian beans: Dioclea guianensis-DguiL; D. grandiflora-DgL; Cratylia

Crystallization and characterization of an inflammatory lectin purified from the seeds of Dioclea wilsonii.

Numai utilizatorii înregistrați pot traduce articole

DwL, a lectin extracted from the seeds of Dioclea wilsonii, is a metalloprotein with strong agglutinating activity against rabbit and ABO erythrocytes, inhibited by glucose and mannose. DwL was purified by affinity chromatography on a Sephadex G-50 column and ion exchange chromatography on a HiTrap

Dioclea violacea lectin ameliorates oxidative stress and renal dysfunction in an experimental model of acute kidney injury.

Numai utilizatorii înregistrați pot traduce articole

Acute kidney injury (AKI) is characterized by rapid and potentially reversible decline in renal function; however, the current management for AKI is nonspecific and associated with limited supportive care. Considering the need for more novel therapeutic approaches, we believe that lectins from

Pharmacological analysis of the neutrophil migration induced by D. rostrata lectin: involvement of cytokines and nitric oxide.

Numai utilizatorii înregistrați pot traduce articole

In the present study, we investigated the involvement of resident cell and inflammatory mediators in the neutrophil migration induced by chemotactic activity of a glucose/mannose-specific lectin isolated from Dioclea rostrata seeds (DrosL). Rats were injected i.p. with DrosL (125-1000

Is the orofacial antinociceptive effect of lectins intrinsically related to their specificity to monosaccharides?

Numai utilizatorii înregistrați pot traduce articole

Lectins are proteins of non-immunological origin that may play several biological applications, of which we can highlight the anti-inflammatory and antinociceptive activities. In this work, we evaluated the possible effect of orofacial antinociceptive activity of three plant lectins, Dioclea

Pharmaceutical properties and toxicology of Dioclea grandiflora.

BACKGROUND Since the beginning of civilization, herbal medicines have been an important source for human beings to treat their ailments. Despite the large number of synthetic remedies available in the market, the use of plants is seen as a great challenge in the search for new substances endowed

Differences in macrophage stimulation and leukocyte accumulation in response to intraperitoneal administration of glucose/mannose-binding plant lectins.

Numai utilizatorii înregistrați pot traduce articole

Peritoneal macrophage stimulation (rapid spreading on glass surface and hydrogen peroxide production) and inflammatory reaction (leukocyte accumulation) obtained in C3H/HeJ mice at 8 weeks of age, after a single ip injection of 10 micrograms concanavalin A (Con A), a lectin extracted from Canavalia

In vivo lymphocyte activation and apoptosis by lectins of the Diocleinae subtribe.

Numai utilizatorii înregistrați pot traduce articole

This paper reports the overall effects of three lectins, extracted from Canavalia brasiliensis, Dioclea violacea, and D. grandiflora, on BALB/c mice popliteal draining lymph nodes. These lectins have presented high stimulatory capacity on lymph node T cells. Additionally, they were able to induce

Rat paw edema and leukocyte immigration induced by plant lectins.

Numai utilizatorii înregistrați pot traduce articole

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

Antinociceptive and toxicological effects of Dioclea grandiflora seed pod in mice.

Numai utilizatorii înregistrați pot traduce articole

The acute treatment of mice with an ethanolic extract from the seed pod of Dioclea grandiflora (EDgP) at doses of 75, 150 and 300 mg/kg by intraperitoneal administration produced a significant antinociceptive effect as displayed by the acetic acid-induced writhing test and the formalin test. The

Molecular modeling, docking and dynamics simulations of the Dioclea lasiophylla Mart. Ex Benth seed lectin: An edematogenic and hypernociceptive protein.

Numai utilizatorii înregistrați pot traduce articole

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
