We measured arterio-venous differences in concentrations of tumor necrosis factor-alpha (TNF alpha) and interleukin-6 (IL-6) across a sc adipose tissue bed in the postabsorptive state in 39 subjects [22 women and 17 men; median age, 36 yr (interquartile range, 26-48 yr); body mass index, 31.8 kg/m2 (range, 22.3- 38.7 kg/m2); percent body fat, 28.7% (range,(More)
Quantitative measurement of NF-kappaB nuclear translocation is an important research tool in cellular immunology. Established methodologies have a number of limitations, such as poor sensitivity, high cost or dependence on cell lines. Novel imaging methods to measure nuclear translocation of transcriptionally active components of NF-kappaB are being used(More)
The early role of natural killer cells and gamma delta T cells in the development of protective immunity to the blood stage of nonlethal Plasmodium yoelii infection was studied. Splenic cytokine levels were measured 24 h after infection of natural killer cell-depleted immunodeficient and littermate mice or transiently T-cell-depleted normal mice. Splenic(More)
BACKGROUND Receptor-mediated signal transduction requires the assembly of multimeric complexes of signalling proteins, and a number of conserved protein domains, such as the SH2, SH3 and PH domains, are involved in mediating protein-protein interactions in such complexes. The identification of binding partners for these domains has added considerably to our(More)
Myeloperoxidase (MPO) is a major protein constituent of the primary granules of vertebrate neutrophils. It catalyses the hydrogen peroxide-mediated oxidation of halide ions to hypohalous acids, especially HOCl. These reactive oxygen species can participate in a variety of secondary reactions, leading to modifications of amino acids and many types of(More)
The tuberculin skin test (TST) is a model of integrated innate and adaptive human immune responses to Mycobacterium tuberculosis, but the component processes that are involved in this model have not previously been defined in vivo. We used transcriptional profiling to study these responses within the TST at molecular and system levels. Skin biopsies from(More)
A 2014 external review of medical schools in Israel identified several issues of importance to the nation's health. This paper focuses on three inter-related policy-relevant topics: planning the physician and healthcare workforce to meet the needs of Israel's population in the 21(st) century; enhancing the coordination and efficiency of medical education(More)
The morphology of antigen-presenting dendritic cells (DCs) is characterized by the presence of numerous long dendrites. The formation of these processes is shown to require the interaction between the beta1-integrin (CD29) on the surface of the DCs and fibronectin in the extracellular matrix. This interaction occurs at focal contacts formed at the tips of(More)
Medical education is a dynamic and continually evolving process, some of which is style, and some of which is linked to changing perspectives in medical practice. A paper by Reis et al., taken in conjunction with the recent paper from an ad hoc International Review Committee (Schoenbaum et al.), provides a reflective view of where Israeli medical education(More)
