1. Immune development in HIV-exposed uninfected children born to HIV-infected women
ABSTRACT Immunological and clinical findings suggestive of some immune dysfunction have been reported among HIV-exposed uninfected (HEU) children and adolescents. Whether these defects are persistent or transitory is still unknown. HEU pediatric population at birth, 12 months, 6-12 years were evaluated in comparison to healthy age-matched HIV-unexposed contr

2. Endocarditis by Kocuria rosea in an immunocompetent child
Kocuria roseabelongs to genus Kocuria(Micrococcaceaefamily, suborder Micrococcineae, order Actinomycetales) that includes about 11 species of bacteria. Usually, Kocuria spare commensal organisms that colonize oropharynx, skin and mucous membrane; Kocuria spinfections have been described in the last decade commonly affecting immunocompromised patients, using

3. Padronização do perfil hematológico, bioquímico, proteinograma sérico e imunofenotipagem de linfócitos de cães da raça Golden Retriever sadios e afetados pela distrofia muscular / Standardization of hematological, biochemical, serum protein concentrations and lymphocyte immunophenotyping of Golden Retriever dogs healthy and affected by muscular dystrophy
Idealizou-se o presente ensaio com o objetivo de padronizar o perfil hematológico, bioquímico, eletroforético (proteinograma sérico) e quantificação das células linfocitárias CD4, CD5, CD8 por citometria de fluxo de cães da raça Golden Retrivier normais (grupos GR) e de cães distróficos (grupos GRMD). Para tanto, considerou-se a divisão dos grup

4. ParÃmetros de normalidade do sistema imunolÃgico no idoso em Fortaleza - Cearà / The immune system normal parameters in elderly people in Fortaleza Ceara
Worldwide, the number of individuals whose age is over 60 years will grow exponentially. Is provided an increase of 694 million in the number of older people in 2025. Ageing is a complex process that negatively impacts the development of the immune system and its ability to function. Immunosenescence is a multifactorial condition leading to many pathological

5. Imbalance of naive and memory T lymphocytes with sustained high cellular activation during the first year of life from uninfected children born to HIV-1-infected mothers on HAART
The immune consequences of in utero HIV exposure to uninfected children whose mothers were submitted to highly active antiretroviral therapy (HAART) during gestation are not well defined. We evaluated 45 HIV-exposed uninfected (ENI) neonates and 45 healthy unexposed control (CT) neonates. All HIV-infected mothers received HAART during pregnancy, and the vira

6. The sample processing time interval as an influential factor in flow cytometry analysis of lymphocyte subsets
The objective of this paper is to propose a protocol to analyze blood samples in yellow fever 17DD vaccinated which developed serious adverse events. We investigated whether or not the time between sample collection and sample processing could interfere in lymphocyte subset percentage, for it is often impossible to analyze blood samples immediately after col

7. Avaliação da reconstituição imunológica e da resposta anti-citomegalovirus nos receptores de transplante de medula óssea / Anti-cytomegalovirus immunity reconstitution following autologous and allogeneic stem cell and bone marrow transplantation as assessed by CD8+ T cell phenotyping and functio
O citomegalovírus (CMV) é uma séria ameaça aos receptores de transplante de medula óssea. A reativação está associada com uma imunidade mediada por células TCD8+ defeituosa. Nosso objetivo foi correlacionar as diferentes subpopulações de células TCD8+ com a reconstituição imunológica dos pacientes, especificamente a imunidade anti-CMV, analisa

Schistosomiasis mansoni is an infectious disease caused by a worm (Schistosoma mansoni), which has the human as one of the definitive hosts in its evolutive course. In more advanced stages, massive embolization by eggs layed in the portal venous sistems by adult forms of the parasite to the hepatic parenchima occurs; this leads to inflammatory reactions in t

9. Preservation of Lymphocyte Immunophenotype and Proliferative Responses in Cryopreserved Peripheral Blood Mononuclear Cells from Human Immunodeficiency Virus Type 1-Infected Donors: Implications for Multicenter Clinical Trials
Human immunodeficiency virus type 1 (HIV-1) infection results in impaired immune function that can be measured by changes in immunophenotypically defined lymphocyte subsets and other in vitro functional assays. These in vitro assays may also serve as early indicators of efficacy when new therapeutic strategies for HIV-1 infection are being evaluated. However

10. Multiparametric immunophenotyping of B cells in peripheral blood of healthy adults by flow cytometry.
The investigation of patients suffering from malignant lymphomas of the B-cell type requires flow cytometric immunophenotyping. Several reports described the expression of almost all B lineage antigens on normal and abnormal B lymphocytes. Thus, immunophenotyping of lymphomas must be interpreted in the context of the reference values obtained for healthy con

11. Lymphocyte subpopulation reference ranges for monitoring human immunodeficiency virus-infected Chinese adults.
Two hundred eight healthy human immunodeficiency virus (HIV) type 1- and HIV type 2-seronegative Chinese adults (78 males and 130 females; mean age, 32 years; age range, 18 to 71 years) were analyzed for lymphocyte subsets by a standardized and quality-controlled flow cytometric immunophenotyping technique. While the leukocyte differential values were compar

12. Timing of lymphocyte activation in neonates infected with human immunodeficiency virus.
Human immunodeficiency virus (HIV) infection in children is associated with qualitative and quantitative changes in the peripheral lymphocyte surface phenotype beyond the normal maturational changes. Neonates, however, have been reported to have a delayed immune response to HIV compared to HIV-infected adults. We prospectively performed immunophenotyping of
