25. The ability of haemolysins expressed by atypical enteropathogenic Escherichia coli to bind to extracellular matrix components
Typical and atypical enteropathogenic Escherichia coli (EPEC) are considered important bacterial causes of diarrhoea. Considering the repertoire of virulence genes, atypical EPEC (aEPEC) is a heterogeneous group, harbouring genes that are found in other diarrheagenic E. coli pathotypes, such as those encoding haemolysins. Haemolysins are cytolytic toxins tha

26. Estudo imunohistoquímico da composição estrômato-vascular dos pólipos tonsilares / Immunohistochemical study of the stromal and vascular components of the tonsillar polyps
Tonsillar polyps are nonneoplastic lesions usually composed of a variable amounts of lymphoid, vascular and connective tissues. All are generally assumed to be hamartomatous proliferations but the profile of vascular and connective components has yet to be explored. The vascular system of the tonsils is complex and includes highly specialized structures (i.e

27. Papel das hemaglutininas 67-72p de Corynebacterium diphtheriae na ligação a proteínas plasmáticas, superfícies celulares, invasão e indução de apoptose / Participation of hemagglutinin 67-72p of corynebacterium diphtheriae in binding to plasma proteins, cells surfaces, invasion and induction of apoptosis
Corynebacterium diphtheriae pode ser isolado tanto de quadros de difteria clássica, quanto de infecções sistêmicas, como endocardite. O fibrinogênio (Fbn) e a fibronectina (Fn) são glicoproteínas presentes na matriz extracelular de tecidos conjuntivos. A influência destas proteínas na patogênese das infecções locais e invasivas causadas por C. di

28. Mechanism of the transforming growth factor-β induction of fibronectin expression in hepatic stem-like cells
Transforming growth factor-β1 (TGF-β1) plays an important role in the fibrogenic process in the liver. The aim of the present study was to explore the action of TGF-β1 on fibronectin expression in rat hepatic stem-like cells and the underlying mechanisms. The level of fibronectin expression was determined in hepatic stem-like cells (WB cells) before and a

29. Expression and possible functional role of galectin-3 in the / Expressão e possível papel funcional da galectina-3 no timo de camundongos diabéticos não-obesos (NOD)
Galectin-3 belongs to a family of endogenous lectins which bind to -galactosides presented on the cell surface and extracellular matrix glycoproteins. It is involved in multiple biological functions such as cell growth, adhesion, proliferation and apoptosis. Moreover, galectin-3 is found in several tissues and organs, being highly conserved among animal spec

30. The EG95 antigen of Echinococcus spp. contains positively selected amino acids, which may influence host specificity and vaccine efficacy
Echinococcosis is a worldwide zoonotic parasitic disease of humans and various herbivorous domestic animals (intermediate hosts) transmitted by the contact with wild and domestic carnivores (definitive hosts), mainly foxes and dogs. Recently, a vaccine was developed showing high levels of protection against one parasite haplotype (G1) of Echinococcus granulo

31. Evaluation on the involvement of Galatrox, a lactose binding lectin isolated from Bothrops atrox venom, on the inflammatory process / Avaliação do envolvimento da Galatrox, uma lectina ligante de lactodr isolada da peçonha de Bothrops atrox, no processo inflamatório
Lectins are proteins with no enzymatic activity and are able to bind specifically and non-covalently (reversible manner) to carbohydrates. In addition, these proteins are involved in several physiological and pathological events, as embryogenesis, immune response, cancer, and others. Galatrox, a lactose-binding protein, was purified from Bothrops atrox snake

32. Resposta do condrócito, proteoglicana, colágeno e fibronectina da cartilagem articular, após aplicação de um protocolo de imobilização, alongamento e remobilização articular
A função da cartilagem articular é dependente do condrócito e dos componentes de sua matriz extracelular, que por sua vez, podem ser regulados por estímulos mecânicos. Assim, alterações no suporte de carga podem afetar sua composição ou sua estrutura e interferir na sua capacidade funcional de sustentar e distribuir cargas e minimizar os estresses

33. Caracterizações biológicas das proteínas LipL32 e HlyX de Leptospira interrogans sorovar Copenhageni. / Biology characterizations of LipL32 and HlyX proteins of Leptospira interrogans sorovar Copenhageni.
Leptospirosis, a spirochaetal zoonotic disease caused by Leptospira, has been recognized as na important emerging infectious disease. LipL32 is a surface lipoprotein which is highly conserved among pathogenic Leptospira species and is also expressed at high levels either during cultivation and natural infection. Regarding HlyX, it has been annotated as a pro

34. The effect of APRIL on the migration of thymocytes / O efeito de APRIL na migração de timócitos
Proteins of the tumor necrosis factor (TNF) family play an important role in many biological processes like cell proliferation, differentiation, survival and death. APRIL (A Proliferation-Inducing Ligand) is a member of this cytokine family, promotes tumor proliferation and survival, and modulates B cells activities, enhancing cell survival and antibody prod

35. Componentes da matriz extracelular e seus reguladores no músculo liso brônquico na asma / Extracellular matrix components and regulators in the airway smooth muscle in asthma
There is an intimate relationship between the extracellular matrix (ECM) and smooth muscle cells within the airways. Few studies have comprehensively assessed the composition of different ECM components and its regulators within the airway smooth muscle (ASM) in asthma. With the aid of image analysis, the fractional area of total collagen and elastic fibres

The whole-genome sequences of L. interrogans serovar Copenhageni and the bioinformatic tools allow us to choose fifteen genes encoding for conserved hypothetical proteins predicted to be exported to the membrane. The chosen genes were amplified by PCR from six predominant pathogenic serovars, the DNA cloned in an E. coli vector, the recombinant proteins expr
