25. Influence of point variants of pattern recognition receptors in the susceptibility to human malaria / Influência de variantes de receptores de reconhecimento padrão na suscetibilidade à malária
Malaria is one of the major causes of disease and death worldwide, mainly of children. It is also the strongest known force for evolutionary selection in the recent history of the human genome. Besides environmental and parasite factors, host genetic factors play a major role in determining both susceptibility to malaria and the course of infection. Innate i

26. Polymorphism in the promoter region of the mannose-binding lectin gene among human T-cell lymphotropic virus infected subjects
The present study investigated the frequency of the mutations at positions -550 and -221 of the mannose-binding lectin (MBL) gene in a sample of 75 human T-cell lymphotropic virus (HTLV) infected patients and 96 HTLV seronegative controls, in order to evaluate the occurrence of a possible association between the polymorphism and HTLV infection. A sequence sp

27. Baixos nÃveis de lectina ligante de manose podem estar associados a uma maior predisposiÃÃo à doenÃa pelo vÃrus respiratÃrio sincicial sem interferir na ativaÃÃo de linfÃcitos T
Respiratory syncytial virus (RSV) is a major cause of serious lower respiratory tract disease among infants and young children worldwide, and understanding the immune response to its infection is essential for intervention strategies. The innate-response serum mannose-binding lectin (MBL), which recognizes a broad range of pathogens and subsequently activate

28. Abordagens biotecnolÃgicas do Tambaqui (Colossoma macropomum)
O tambaqui (Colossoma macropomum) Ã um peixe com ampla distribuiÃÃo nos rios da RegiÃo Norte e uma das espÃcies de maior importÃncia na alimentaÃÃo da populaÃÃo desta RegiÃo. Este peixe vem, nas Ãltimas dÃcadas, se tornando uma das principais espÃcies nativas para a piscicultura brasileira, apresentando um Ãtimo padrÃo de crescimento e alta p

29. Study of the insecticide and pro-inflammatory activity of lectin isolated from annona coriacea mart seeds / Estudo da atividade inseticida e pro-inflamatoria da lectina isolada de sementes de Annona coriacea Mart
Lectins are a group of proteins and/or glycoproteins, which exhibit specific and reversible carbohydrate-binding activities. Studies have demonstrated that such proteins possess important biological activities including insecticide activity as well as immunological and physiological responses in animals. In this investigation, our aim was to compare the effe

30. Expression of the receiver for mannose in cells of Schwann and Schwannoma ST88-14. / Expressão do receptor para manose em células de Schwann e Schwannoma ST88-14.
The mannose receptor (MR) is a transmembrane glycoprotein that is expressed in several cell types but little or no information is available on Schwann cells (SC). We show that rodent SC in primary cultures of dissociated cells or explant nerve cultures and a human Schwannoma cell line (ST88-14) bind the exogenous MR ligand neoglycoprotein mannosyl/bovine ser

31. Trypanosoma cruzi e o Sistema Complemento: Mecanismos de ativação e o papel do gene CRIT (Complement C2 Receptor Inhibitor Trispanning) na resistência à lise em cepas de classe I e II / Trypanosoma cruzi E O SISTEMA COMPLEMENTO: MECANISMOS DE ATIVAÇÃO E O PAPEL DO GENE CRIT (COMPLEMENT C2 RECEPTOR INHIBITOR TRISPANNING) NA RESISTÊNCIA À LISE EM CEPAS DE CLASSE I E II / Trypanosoma cruzi e o Sistema Complemento: Mecanismos de ativação e o papel do gene CRIT (Complement C2 Receptor Inhibitor Trispanning) na resistência à lise em cepas de classe I e II / Trypanosoma cruzi E O SISTEMA COMPLEMENTO: MECANISMOS DE ATIVAÇÃO E O PAPEL DO GENE CRIT (COMPLEMENT C2 RECEPTOR INHIBITOR TRISPANNING) NA RESISTÊNCIA À LISE EM CEPAS DE CLASSE I E II
Trypanosoma cruzi, the agent of Chagas disease, infects 18 million people in Latin America. T. cruzi has an heteroxicenous life cycle infecting vertebrates and invertebrate hosts. Two classes of T. cruzi have been proposed based on molecular markers, the class I with a sylvatic life cycle infecting mostly marsupials, while class II parasites have a domestic

32. Levana Ferromagnetizada: uma matriz de afinidade para purificar lectina de sementes de Cratylia mollis (Cramoll 1)
Levans, fructose polymer, are composed by β-2,6 linkages and can be produced by differents species of plants and bacteria . Applications for levans have been suggested in food industries, pharmaceutics, also in medicine. Ferromagnetic particle in biomedical and industrial areas have been used. Lectins find are ubiquitously distributed in nature, and occ

33. Differential effect of plant lectins on mast cells of different origins
Histamine release induced by plant lectins was studied with emphasis on the carbohydrate specificity, external calcium requirement, metal binding sites, and mast cell heterogeneity and on the importance of antibodies bound to the mast cell membrane to the lectin effect. Peritoneal mast cells were obtained by direct lavage of the rat peritoneal cavity and gui

34. Evaluation of the structural lectin binding protein (MBL) gene and its relationship with maternal-to-child HIV transmission / "Avaliação do gene estrutural da proteína de ligação à lectina (MBL) e sua relação com a transmissão materno-fetal do HIV"
Avaliou-se a expressão do gene mbl2 em 79 crianças e suas mães HIV positivas com o objetivo de avaliar a sua influência na transmissão vertical. Os pacientes divididos em dois grupos: crianças HIV positivas e suas mães (n=18) e crianças HIV negativas e suas mães (n=61) foram avaliados pelo CH50 e AP50 (ensaios hemolíticos), dosagem e avaliação fu

35. Mannose-Binding Lectin Binds to a Range of Clinically Relevant Microorganisms and Promotes Complement Deposition
Mannose-binding lectin (MBL) is a collagenous serum lectin believed to be of importance in innate immunity. Genetically determined low levels of the protein are known to predispose to infections. In this study the binding of purified MBL to pathogens isolated from immunocompromised children was investigated by flow cytometry. Diverse Candida species, Aspergi

36. The Liverwort Contains a Lectin That Is Structurally and Evolutionary Related to the Monocot Mannose-Binding Lectins1
A mannose (Man)-binding lectin has been isolated and characterized from the thallus of the liverwort Marchantia polymorpha. N-terminal sequencing indicated that the M. polymorpha agglutinin (Marpola) shares sequence similarity with the superfamily of monocot Man-binding lectins. Searches in the databases yielded expressed sequence tags encoding Marpola. Sequ
