25. Differential expression of immunologic proteins in gingiva after socket preservation in mini pigs
During healing following tooth extraction, inflammation and the immune response within the extraction socket are related to bone resorption. Objective : We sought to identify how the alloplastic material used for socket preservation affects the immune responses and osteoclastic activity within extraction sockets. Material and Methods : Using a porcine model,

26. Role of chemokines in promoting instability of coronary atherosclerotic plaques and the underlying molecular mechanism
Our aim was to investigate the role of chemokines in promoting instability of coronary atherosclerotic plaques and the underlying molecular mechanism. Coronary angiography and intravascular ultrasound (IVUS) were performed in 60 stable angina pectoris (SAP) patients and 60 unstable angina pectoris (UAP) patients. The chemotactic activity of monocytes in the

27. The Duffy binding protein as a key target for a Plasmodium vivax vaccine: lessons from the Brazilian Amazon
Plasmodium vivax infects human erythrocytes through a major pathway that requires interaction between an apical parasite protein, the Duffy binding protein (PvDBP) and its receptor on reticulocytes, the Duffy antigen/receptor for chemokines (DARC). The importance of the interaction between PvDBP (region II, DBPII) and DARC to P. vivax infection has motivated

28. Immune responses to Leptospira infection: roles as biomarkers for disease severity
Various leptospiral components have been identified and shown to be involved in tissue destruction. In addition, immune responses to leptospires have been implicated in target organ damages in severe leptospirosis cases. Several inflammatory mediators were shown to be higher in susceptible animals than in resistant hosts. Moreover, cytokines/chemokines and s

29. Chemokines and chemokine receptors expression in the lesions of patients with American cutaneous leishmaniasis
American cutaneous leishmaniasis (ACL) presents distinct active clinical forms with different grades of severity, known as localised (LCL), intermediate (ICL) and diffuse (DCL) cutaneous leishmaniasis. LCL and DCL are associated with a polarised T-helper (Th)1 and Th2 immune response, respectively, whereas ICL, or chronic cutaneous leishmaniasis, is associat

30. Involvement and interactions of different immune cells and their cytokines in human visceral leishmaniasis
Visceral leishmaniasis (VL) or kala-azar, a disseminated infection of the lymphoreticular system of the body, is marked by severe defect in immune system of the host. Successful cure of VL depends on the immune status of the host in combination with the effects of the antileishmanial drugs. The rationale approach towards eradication of this disease would be

32. CCL3 and CXCL12 production in vitro by dental pulp fibroblasts from permanent and deciduous teeth stimulated by Porphyromonas gingivalis LPS
Objective: The aim of this study was to compare the production of the chemokines CCL3 and CXCL12 by cultured dental pulp fibroblasts from permanent (PDPF) and deciduous (DDPF) teeth under stimulation by Porphyromonas gingivalis LPS (PgLPS). Material and Methods: Primary culture of fibroblasts from permanent (n=3) and deciduous (n=2) teeth were established

33. Pathophysiology of bacterial infection of the central nervous system and its putative role in the pathogenesis of behavioral changes
Invasion of the central nervous system (CNS) by microorganisms is a severe and frequently fatal event during the course of many infectious diseases. It may lead to deafness, blindness, cerebral palsy, hydrocephalus, cognitive impairment or permanent neurological dysfunction in survivors. Pathogens can cross the blood-brain barrier by transcellular migration,

34. Avaliação do papel dos receptores TLR2 e TLR4 na produção de citocinas por fibroblastos humanos periodontais deficientes desses receptores / The role of TLR2 and TLR4 in cytokines production by human periodontal fibroblasts knocked down for these receptors
Os fibroblastos são atualmente considerados componentes ativos da resposta imune porque estas células expressam receptores do tipo Toll (TLRs), são capazes de reconhecer padrões moleculares associados a patógenos e mediar a produção de citocinas e quimiocinas durante a inflamação. A resposta imune inata do hospedeiro a lipopolissacarídeos (LPS) de

35. Avaliação da capacidade funcional de eosinófilos do sangue periférico de pacientes com a forma juvenil da paracoccidioidomicose = : Evaluation of functional capacity of peripheral blood eosinophils of patients with the juvenile form of paracoccidioidomycosis / Evaluation of functional capacity of peripheral blood eosinophils of patients with the juvenile form of paracoccidioidomycosis
Pacientes com a forma juvenil da paracoccidioidomicose (PCM) apresentam resposta imune celular deprimida, evidenciada por teste de hipersensibilidade do tipo tardio negativo e proliferação linfocitária deficiente a antígenos do fungo e pela produção de citocinas do tipo TH2 como IL-4, IL-5, IL-10 e TGF-?. Além disso, um aspecto comum desta forma da do

36. Pb x laserterapia : mecanismos envolvidos na cicatrização de lesões cutâneas / PB x phototherapy : wound healing mechanisms of cutaneous lesions
Our group has been exploring the biological mechanisms underlying the inflammatory process of paracoccidioidomycotic lesions treated by HeNe laser on cutaneous lesions caused by the inoculation of yeast cells into the back foot-pad of Balb/c mice. In this work we showed that laser-treated mice presented reduction of footpad edema, greater histologic organiza
