Because of the low stoichiometry of protein phosphorylation, targeted enrichment prior to LC–MS/MS analysis is still essential. The trend in phosphoproteome analysis is shifting toward an increasing number of biological replicates per experiment, ideally starting from very low sample amounts, placing new demands on enrichment protocols to make …
Epstein-Barr virus, a B-lymphotropic herpesvirus, is the cause of infectious mononucleosis, has strong aetiologic links with several malignancies and has been implicated in certain autoimmune diseases. Efforts to develop a prophylactic vaccine to prevent or reduce EBV-associated disease have, to date, focused on the induction of neutralising antibody responses. However …
Current biomarkers of renal disease in systemic vasculitis lack predictive value and are insensitive to early damage. To identify novel biomarkers of renal vasculitis flare, we analysed the longitudinal urinary metabolomic profile of a rat model of anti-neutrophil cytoplasmic antibody (ANCA) vasculitis. Wistar-Kyoto (WKY) rats were immunised with human myeloperoxidase …
Common bean (Phaseolus vulgaris L.) is one of the most consumed staple foods worldwide. Little is known about the molecular mechanisms controlling seed development. This study aims to comprehensively describe proteome dynamics during seed development of common bean. A high-throughput gel-free proteomics approach (LC–MS/MS) was conducted on seeds …

Metabolomics studies have been reported for virtually all of the main rheumatologic diseases, although notably none yet for SSc. Our own group has demonstrated the use of urinary metabolic fingerprint analysis to predict responses to anti-TNF, and we have suggested that metabolites resulting from TNF-driven cachexia are among the useful …

Background Metabolomics is a systems approach to the analysis of cellular processes through small-molecule metabolite profiling. Standardisation of sample handling and acquisition approaches has contributed to reproducibility. However, the development of robust methods for the analysis of metabolomic data is a work-in-progress. The tools that do exist are often not …

OBJECTIVE: Anti-tumor necrosis factor (anti-TNF) therapies are highly effective in rheumatoid arthritis (RA) and psoriatic arthritis (PsA), but a significant number of patients exhibit only a partial or no therapeutic response. Inflammation alters local and systemic metabolism, and TNF plays a role in this. We undertook this study to determine …
Inflammation is an important component of normal responses to infection and injury. However, chronic activation of the immune system, due to aberrant responses to normal stimuli, can lead to the establishment of a persistent inflammatory state. Such inflammatory conditions are often debilitating, and are associated with a number of important …

Metabolomics in the Analysis of Inflammatory Diseases is chapter 11 in the open-access book Metabolomics edited by Ute Roessner.
Metabolomics is a rapidly emerging field in life sciences, which aims to identify and quantify metabolites in a biological system. Analytical chemistry is combined with sophisticated informatics and statistics tools to …

Macrophages have a wide range of immunological and non-immunological functions in the host, ranging from clearance of apoptotic cells, tissue remodelling, and release of pro and anti-inflammatory mediators at site of tissue damage or infection. Within these wide-ranging functions however, subsets of macrophages show unique phenotypic adaptations to their role …
Epstein-Barr virus is a γ-herpesvirus endemic (>90%) in the human population and implicated in a variety of lymphomas and solid tumours including Hodgkin’s lymphoma, Burkitt’s lymphoma and post-transplant lymphoproliferative disorder. Despite the prevalence of EBV, little is known about the mechanisms of early infection, including the role of …
