There is considerable heterogeneity in immunological parameters between individuals, but its sources are largely unknown. To assess the relative contribution of heritable versus non-heritable factors, we have performed a systems-level analysis of 210 healthy twins between 8 and 82 years of age. We measured 204 different parameters, including cell population(More)
The immunology database and analysis portal (ImmPort) system is the archival repository and dissemination vehicle for clinical and molecular datasets created by research consortia funded by the National Institute of Allergy and Infectious Diseases Division of Allergy, Immunology, and Transplantation. With nearly 100 datasets now publicly available and(More)
Gene-expression profiling has become a mainstay in immunology, but subtle changes in gene networks related to biological processes are hard to discern when comparing various datasets. For instance, conservation of the transcriptional response to sepsis in mouse models and human disease remains controversial. To improve transcriptional analysis in(More)
Data generated by the numerous clinical trials conducted annually worldwide have the potential to be extremely beneficial to the scientific and patient communities. This potential is well recognized and efforts are being made to encourage the release of raw patient-level data from these trials to the public. The issue of sharing clinical trial data has(More)
To date, our understanding of a normal immune system is far behind that of other healthy organ systems. One reason for this is the lack of standardization in the lab techniques, especially flow cytometry. To take a step towards the characterization of a normal immune system, we re-analyzed and combined data that was made publicly available through the(More)
Broad open access to entire clinical research studies data is on the rise. Public access to raw clinical research data has created tremendous opportunity to evaluate new research hypotheses that were not originally formulated in the studies; by reanalyzing data from a study, by performing cross analysis of multiple studies, or by combining study data with(More)
The genes that produce antibodies and the immune receptors expressed on lymphocytes are not germline encoded; rather, they are somatically generated in each developing lymphocyte by a process called V(D)J recombination, which assembles specific, independent gene segments into mature composite genes. The full set of composite genes in an individual at a(More)
Studies have shown a large number of immune related diseases, in particular auto-immune diseases, to have a genetic component. The immune system is dependent on the functionality of a multitude of components, key factors of which are the different immune cell-type subsets and the cytokines to which they respond to or secrete. However, the abundance of(More)
