Tyrosine kinase activity associated with the CD7 antigen: correlation with regulation of T cell integrin function
(WILEY-VCH Verlag GmbH, 1994-11)
Rapid up-regulation of the functional activity of integrin adhesion receptors is a hallmark of T cell activation. Monoclonal antibody engagement of the CD7 antigen on human T cells results in an increase in Β1 and Β2 ...
Immunological functions of non-professional antigen-presenting cells: new insights from studies of T-cell interactions with keratinocytes
(Elsevier, 1994-10)
T-cell activation in the absence of co-stimulatory signals can lead to induction of anergy. Professional antigen-presenting cells (APCs) of bone marrow origin, such as macrophages and dendritic cells, can provide co-stimulation ...
Enhanced diagnostic efficiency of the polymerase chain reaction by co-amplification of multiple regions of HIV-1 and HIV-2
(Elsevier, 1994-08)
A method for co-amplification of multiple viral sequences of HIV-1 and HIV-2 by polymerase chain reaction was designed. The technique resulted in the specific detection of each type of virus and allowed the amplification ...
Costimulation of Superantigen-Activated T Lymphocytes by Autologous Dendritic Cells Is Dependent on B7
(Elsevier, 1994-06)
Highly purified populations of dendritic cells (DCs) can be isolated from various tissues such as skin and blood. These sites are likely to encounter secreted toxins of bacteria such as super-antigens. In vivo, DCs express ...
Immunoglobulin G directed against toxins A and B of Clostridium difficile in the general population and patients with antibiotic-associated diarrhea
(Elsevier, 1994-04)
Serum immunoglobulin G (IgG) class antibodies directed against toxins A and B of Clostridium difficile were studied using an enzyme-linked immunosorbent assay and a serum-neutralizing assay based on the MRC-5 tissue ...
c-Myc Does Not Require Max for Transcriptional Activity in PC-12 Cells
(Elsevier, 1994-06)
The c-Myc proto-oncogene is a basic helix-loop-helix leucine zipper (b/HLH/LZ) protein that participates in cellular growth and differentiation. The expression of cMyc mRNA is rapidly induced by nerve growth factor (NGF) ...
Cell-Specific Kinetics and Efficiency of Herpes Simplex Virus Type 1 Entry Are Determined by Two Distinct Phases of Attachment
(Elsevier, 1994-02-01)
We previously provided evidence for a model of herpes simplex virus type 1 (HSV-1) entry by a cascade of interactions between components of the virion envelope and cellular plasma membrane (Fuller and Lee, 1992, J. Virol. ...
Fas ligation triggers apoptosis in macrophages but not endothelial cells
(WILEY-VCH Verlag GmbH, 1994-11)
The reticuloendothelial system includes macrophages and endothelial cells. These cells are produced and destroyed in vivo with a precision that implies the existence of homeostatic mechanisms. The stimuli for endothelial ...
Tissue engineering of a bioartificial kidney
(Wiley Subscription Services, Inc., A Wiley Company, 1994-03-25)
Tissue engineering is a rapidly growing field in biotechnology. The use and packaging of synthetic materials, biologic compounds, and cellular components of specific tissues can be envisioned to replace physiologic function ...
