1. Schistosoma mansoni antigens alter the cytokine response in vitro during cutaneous leishmaniasis
Schistosoma mansoni infection or associated products are able to down-modulate the type 1 CD4+ T cell inflammatory response characteristic of autoimmune diseases. In this study, we evaluated how S. mansoni antigens altered the immune response that was induced by the soluble Leishmania antigen (SLA) from cutaneous leishmaniasis (CL) patients. Cytokines were m

2. Integrina beta1 no desenvolvimento das glândulas salivares humanas / Integrin beta1 in developing human salivary glands
INTRODUÇÃO: O desenvolvimento das glândulas salivares envolve um processo coordenado de interações moleculares complexas, nas quais as integrinas têm papel fundamental. As integrinas são uma família de receptores transmembrânicos, heterodímeros, compostos por duas subunidades: alfa e beta que estão ligadas de forma não covalente e dependentes de

3. Expressão dos marcadores tumorais CD-34 e CASPASE-3 no carcinoma epidermóide de esôfago
OBJETIVO: Analisar citofotometricamente a expressão do marcador de densidade microvascular CD-34 e de apoptose caspase-3 no carcinoma epidermóide de esôfago, e correlacionar os marcadores entre si. MÉTODOS: Análise imunoistoquímica de 29 peças cirúrgicas de carcinomas epidermóides de esôfago, baseada nos índices de marcagem dos anticorpos CD-34 e

4. Modulação da resposta imune alérgica por antígenos de Schistosoma mansoni
A prevalência das doenças alérgicas vem aumentando nas últimas três décadas, representando um grande problema de saúde pública. A infecção pelo Schistosoma mansoni tem sido associada com a proteção contra alergias. Os mecanismos envolvidos nesta associação incluem a produção de células e citocinas regulatórias. Objetivo: Avaliar a resposta

5. Primary bone lymphomas : comparison of the immunoexpression of apoptosis related proteins and adhesion molecules with nodal lymphomas and lymphomas metastatic to bone / Linfomas osseos primarios : estudo comparativo com linfomas nodais e linfomas osseos metastaticos quanto a imunoexpressão de proteinas relacionadas a apoptose, regulação do ciclo celular e adesão celular
The incidence of extranodal lymphomas is increasing in the last decades. Around 20 to 40% of B-cell non-Hodgkin lymphomas (NHL) arise outside the lymph nodes and may present distinct biological behavior, as compared to the corresponding nodal counterpart of similar histological grade. The heterogeneity of large B-cell lymphomas (LBCL) has been matter of vari

6. Painel racionalizado de anticorpos monoclonais para leucemias agudas : seu valor diagnostico e prognostico
Acute leukemia is characterized by a c1onal proliferation of haematopoietic stem cell substituting the normal bone marrow. The recent WHO c1assification for acute leukemia separates entities by recurrent cytogenetic abnormalities and immunophenotypic features presenting prognostic impact. We have examined the distribution and impact on survival of the expres

7. Decreased T-cell proliferative response to common environmental antigens could be an indicator of early human immunodeficiency virus-mediated lymphocyte lesions.
To evaluate CD4+/CD29+ cells and their responses to different antigens in polar stages of human immunodeficiency virus (HIV) infection, we studied 26 HIV-seropositive carriers (SPCs) and 15 patients with AIDS simultaneously with 20 healthy volunteers (HVs) and 10 seronegative homosexual and bisexual men (SNH). CD3, CD4, CD29, and CD45RA phenotypes were analy

8. Expression of surface antigens distinguishing "naive" and previously activated lymphocytes in bronchoalveolar lavage fluid.
Studies in animals suggest that the initial activation of unprimed ("naive") T lymphocytes by inhaled antigens may occur outside the lung with later recruitment to the lung. If this is true all lymphocytes present in the lung should show evidence of prior activation. To test this hypothesis for lymphocytes present on the alveolar surface, the expression of s

9. Prolonged impairment of very late activating antigen-mediated T cell proliferation via the CD3 pathway after T cell-depleted allogeneic bone marrow transplantation.
One of the major obstacles in allogeneic bone marrow transplantation (allo-BMT) is prolonged T cell dysfunction resulting in a variety of infectious complications in the months to years after hematologic engraftment. We previously showed that immobilized extracellular matrix (ECM) proteins such as fibronectin (FN), the CS-1 domain of FN, or collagen (CO) act

10. HTLV-I associated arthritis: characteristics of an HTLV-I virus infected T cell line from synovial fluid.
A T cell line from mononuclear cells in the synovial fluid of a patient with polyarthritis was established. The T cell line reacted with serum samples positive for antibodies to human T cell lymphotropic virus type I (HTLV-I) and with monoclonal antibody to HTLV-I p19. In Southern blotting with an env-pX-LTR HTLV-I probe and digestion of T cell line DNA with

11. Expanded CD14+ CD16+ Monocyte Subpopulation in Patients with Acute and Chronic Infections Undergoing Hemodialysis
Infections are frequent complications in end-stage renal failure patients undergoing hemodialysis (HD), and peripheral blood monocytes are important cells in host defense against infections. The majority of circulating monocytes express high levels of lipopolysaccharide receptor antigen CD14 and are negative for the immunoglobulin Fcγ receptor type III (CD1

12. Production of T-helper cell subsets and cytokines by lymphocytes from patients with chronic mucocutaneous candidiasis.
Chronic mucocutaneous candidiasis (CMC) is a heterogeneous group of disorders characterized by recurrent and persistent superficial candidal infections. Cytokine-induced dysregulation of T-helper cell function has been described in other immune-deficient states but has not been studied in CMC patients. We studied T-helper cell subsets by flow cytometry and c
