Dr Mady Hornig, MD, Director of Translational Research at the Center for Infection and Immunity at Columbia University, made a presentation at the RME Sweden Severe ME conference in late October last year.  Dr Hornig went into more depth about her published cytokine work and described what her team is working on today.
Dr Hornig spoke about the crisis in funding, looking at gene expression and gene variants, screening for up to 1.7 million vertebrate viruses, metabolomics, and looking at how the immune system and the microbiome could affect metabolism and the brain.  She also spoke about the need to address the heterogeneity in ME/CFS in terms of symptomology but also illness duration and severity: the presence of sub-groups within the illness, each of which presents its own challenges and may require different treatment strategies.
Here is the full transcript of the talk, together with most of the slides.  Thanks to RME Sweden, it is also available to be viewed on YouTube.
