13. 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

14. HHV-8 infection in patients with AIDS-related Kaposi's sarcoma in Brazil
The aims of the present study were to determine the prevalence of human herpesvirus type 8 (HHV-8) in HIV-positive Brazilian patients with (HIV+/KS+) and without Kaposi's sarcoma (HIV+/KS-) using PCR and immunofluorescence assays, to assess its association with KS disease, to evaluate the performance of these tests in detecting HHV-8 infection, and to invest

15. Comparison of dengue infection in human mononuclear leukocytes with mosquito C6/36 and mammalian Vero cells using flow cytometry to detect virus antigen
Fluorescent activated cell sorter (FACS) analysis is useful for the detection of cellular surface antigens and intracellular proteins. We used this methodology in order to detect and quantify dengue antigens in highly susceptible cells such as clone C6/36 (Aedes albopictus) and Vero cells (green monkey kidney). Additionally, we analyzed the infection in vitr

16. 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

17. Immunocytochemical analysis of human synovial lining cells: phenotypic relation to other marrow derived cells.
The antigenic phenotype of human synovial lining cells in normal and hyperplastic synovium intima was determined with a panel of monoclonal antibodies directed against a large number of well defined myeloid (macrophage/granulocyte associated) antigens. Synovial lining cells express numerous macrophage associated antigens, including CD11b (CR3), CD13, CD14, C

18. Immunophenotypic differences between osteoclasts and macrophage polykaryons: immunohistological distinction and implications for osteoclast ontogeny and function.
The antigenic phenotype of human fetal osteoclasts was compared with that of human tissue macrophages and macrophage polykaryons in foreign body lesions using a large number of monoclonal antibodies directed against myeloid (granulocyte/mononuclear phagocyte) antigens. Osteoclasts expressed a restricted range of macrophage-associated antigens including CD13,

19. Immunological and ultrastructural studies in acute biphenotypic leukaemia.
AIMS--To compare the sensitivity of the ultrastructural method to detect myeloperoxidase (MPO) with light microscopy and immunocytochemistry using an anti-MPO antibody; to examine the expression of lymphoid antigens in relation to MPO activity in blast cells from cases of biphenotypic leukaemia. METHODS--Blast cells from 14 cases of biphenotypic acute leukae

20. An NK1.1+ CD4+8- single-positive thymocyte subpopulation that expresses a highly skewed T-cell antigen receptor V beta family.
In the present report we describe a CD4+8- heat stable antigen-negative (HSA-) thymocyte subpopulation that expresses a distinguishably low density of alpha beta T-cell antigen receptors (TCRlo) from the majority of CD4+8- high-density TCR (TCRhi) mature-type thymocytes. This subpopulation appears relatively late in life. Analysis of MEL-14, Pgp-1 (CD44), IC

21. Nef Protein of Human Immunodeficiency Virus and Lipopolysaccharide Induce Expression of CD14 on Human Monocytes through Differential Utilization of Interleukin-10
We investigated the expression of membrane-bound CD14 (mCD14) on monocytes and soluble CD14 (sCD14) released into the culture supernatants of peripheral blood lymphocytes (PBMC) from human immunodeficiency virus (HIV)-infected individuals. Monocytes from HIV-positive individuals exhibited both enhanced mCD14 expression and sCD14 production in the PBMC cultur

22. Potent Immunoregulatory Effects of Salmonella typhi Flagella on Antigenic Stimulation of Human Peripheral Blood Mononuclear Cells
A key function of monocytes/macrophages (Mφ) is to present antigens to T cells. However, upon interaction with bacteria, Mφ lose their ability to effectively present soluble antigens. This functional loss was associated with alterations in the expression of adhesion molecules and CD14 and a reduction in the uptake of soluble antigen. Recently, we have demo

23. The skin homing receptor cutaneous leucocyte-associated antigen (CLA) is up-regulated by Leishmania antigens in T lymphocytes during active cutaneous leishmaniasis
The cutaneous leucocyte-associated antigen receptor (CLA) can direct Leishmania-specific T lymphocytes towards inflamed skin lesions. Homing receptors [CLA, lymphocyte-associated antigen 1 (LFA-1) or CD62L] were analysed in lymphocytes from blood and cutaneous leishmaniasis (CL) lesions. CL patients with active lesions (A-CL) presented lower levels of T lymp

24. A physical map linking the five CD1 human thymocyte differentiation antigen genes.
Human CD1 is a family of thymocyte differentiation antigens which consist of heavy chains with mol. wts between 43 and 49 kd binding to beta 2 microglobulin. They are distant relatives of the major histocompatibility complex (MHC) class I and II products. Five human CD1 genes have been described. Three (CD1A, -B and -C) code for the serologically defined CD1
