1. Inhibitory effect of Lonchocarpus araripensis lectin in rat acute models of inflammation
Abstract: Dalbergieae tribe lectins, possessing binding affinity for galactose and mannose, present inflammatory and nociceptive effects, while those for N-acetylglucosamine are anti-inflammatory. Since the anti-inflammatory effect of the seed lectin of L. araripensis (LAL) had been already demonstrated in mice, this effect was presently evaluated in rat mod

2. Deep sequencing analysis of toad Rhinella schneideri skin glands and partial biochemical characterization of its cutaneous secretion
Abstract Background: Animal poisons and venoms are sources of biomolecules naturally selected. Rhinella schneideri toads are widespread in the whole Brazilian territory and they have poison glands and mucous gland. Recently, protein from toads’ secretion has gaining attention. Frog skin is widely known to present great number of host defense peptides and

3. Detection, purification and characterization of a lectin from freshwater green algae Spirogyra spp.
ABSTRACT Freshwater algae are rich sources of structurally biologically active metabolites, such as fatty acids, steroids, carotenoids and polysaccharides. Among these metabolites, lectins stand out. Lectins are proteins or glycoproteins of non-immune origin which bind to carbohydrates or glycoconjugates, without changing ligand structure. Many studies have

4. Lectin activity in mycelial extracts of Fusarium species
ABSTRACT Lectins are non-immunogenic carbohydrate-recognizing proteins that bind to glycoproteins, glycolipids, or polysaccharides with high affinity and exhibit remarkable ability to agglutinate erythrocytes and other cells. In the present study, ten Fusarium species previously not explored for lectins were screened for the presence of lectin activity. Myce

5. Synthesis, Physicochemical and Photophysical Characterization of 4-(1-Pyrenyl)-butyl-α-D-mannopyranoside
Glycolipids are biomolecules composed of a lipid chain (lipophilic) and a monosaccharide or oligosaccharide as hydrophilic group. Their chemical structure and biological role make them undoubtedly good candidates for a large and continuously growing number of biotechnological applications. Mannose is a carbohydrate present on membrane glycolipids of a wide n

6. Isolation and Characterization of Midgut Lectin From Aedes aegypti (L.) (Diptera: Culicidae)
ABSTRACT The present investigation deals with the isolation and characterization of a lectin from Aedes aegypti (Ae aegypti) female mid gut extract that agglutinates various mammalian red blood cells (RBCs) such as human three groups A, B, and O (RH+), mouse, rat, guinea-pig, sheep and goat erythrocytes. The highest activity of both crude and isolated mid gu

7. Snake venom galactoside-binding lectins: a structural and functional overview
AbstractSnake venom galactoside-binding lectins (SVgalLs) comprise a class of toxins capable of recognizing and interacting with terminal galactoside residues of glycans. In the past 35 years, since the first report on the purification of thrombolectin from Bothrops atrox snake venom, several SVgalLs from Viperidae and Elapidae snake families have been descr

8. Hemagglutinating/Hemolytic activities in extracts of marine invertebrates from the Brazilian coast and isolation of two lectins from the marine sponge Cliona varians and the sea cucumber Holothuria grisea
Vinte espécies de invertebrados marinhos, coletados na costa brasileira, foram avaliados quanto à presença de atividade hemaglutinante/hemolítica. Em pelo menos doze espécies testadas, a atividade hemaglutinante foi diferencial para diferentes grupos sanguíneos, sugerindo a presença de lectinas. Extratos de quatro espécies apresentaram atividade hemo

9. The importance of heat against antinutritional factors from Chenopodium quinoa seeds
Chenopodium quinoa seeds have high protein content. The nutritional value of quinoa is superior compared with traditional cereals. Its essential amino acid composition is considered next to the ideal, and its quality matches that of milk proteins. In this study, the seed storage proteins from Chenopodium quinoa were extracted, fractionated, partially purif

11. Antifungal activity of lectins against yeast of vaginal secretion
Lectins are carbohydrate-binding proteins of non-imune origin. This group of proteins is distributed widely in nature and they have been found in viruses, microorganisms, plants and animals. Lectins of plants have been isolated and characterized according to their chemical, physical-chemical, structural and biological properties. Among their biological activ

12. Análise estrutural do domínio de reconhecimento a carboidratos da lectina Dvirl de Dioclea virgata e sua correlação na indução da produção de óxido nítrico / Structural analysis of the carbohydrate recognition domain the DvirL lectin from Dioclea virgata and its correlation in the induction of nitric oxide production
Lectins are defined as proteins or glycoproteins of nonimmune origin that have at least one site of reversible binding to carbohydrates or glycoconjugates. Lectins of plant origin are the most studied and characterized as three-dimensional structure and biological functions related. Lectins can be found in different parts of the plant from its root to the in
