Pathomx: an interactive workflow-based tool for the analysis of metabolomic data

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 ... Continue reading


Macrophage metabotypes in the hypoxic inflammatory environment assessed using metabolomic profiling

Background: Macrophages are abundant in the synovium of RA and are the major source of many inflammatory cytokines, including TNFα. Disease severity correlates strongly with both synovial macrophage abundance and activation status but inversely with oxygen levels. Given the importance of oxygen to cell metabolism, differentiation and function, we hypothesized ... Continue reading


Metabolomics – a novel window into inflammatory disease

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 ... Continue reading


M1 and M2 macrophages display profoundly different metabolic profiles and IL-10 production under hypoxic conditions

Background: Macrophages have a wide range of immunological and non-immunological functions, ranging from clearance of apoptotic cells, tissue remodelling, and release of pro and anti-inflammatory mediators at sites of tissue damage or infection. Subsets of phenoty- pically distinct macrophages may be uniquely adapted to perform these roles. Phenotypically and functionally ... Continue reading


Do differentiated macrophages display profoundly different metabolic profiles, reflecting their different functions?

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 ... Continue reading


Tracking viral entry into target cells by virological and immunological methods

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 ... Continue reading
