BRMEC13 Colloquium 2023

The thirteenth Invest in ME Research Biomedical Research into ME Colloquium (BRMEC13)—"The Infectious Aetiology of Myalgic Encephalomyelitis"—took place in London over two days: 25th–26th May 2023.

Acknowledging clinical and research consensus on the infectious aetiology of ME/CFS.

The 13th International Biomedical Research into ME Research Colloquium took place on 26 - 27 June 2024 and focused on uncovering the complexities of ME, exploring acute infection, chronic infection, and co-infection. #BRMEC13 introduced a collaborative format with sessions led by experts from the European ME Research Group. These sessions covered various aspects of ME research, facilitating in-depth discussions on Chronic Infection, Nervous System and Neuroinflammation, Immune System, Metabolism, Epigenomes and Transcriptomes, Physiology, and Other Non-Infectious Trauma.
With developments around research into Long Covid and with the similarities of some symptoms to those experienced by people with ME then this topic was also included as a central component of the agenda and a number of presentations concerning ME and long covid were given with a focus on the aetiology of the disease.
The knowledge and the road travelled by ME researchers and clinicians is an invaluable aid for understanding long Covid.
Understanding the viral and immunological mechanisms behind both of those conditions is the key to making progress.

The 13th Biomedical Research into ME Colloquium was possibly the best yet of the series of colloquia that were started in 2011, five years after we initiated the international ME conferences.
This year Invest in ME Research started late in preparations, unsure of the response from researchers following easing of covid restrictions. However, the team managed to bring together a good programme of interesting research and used the expertise of the European ME Research Group (EMERG) to chair sessions and bring in new expertise alongside the existing and increasing family of researchers that the charity has developed.
There was more interest from researchers than ever - despite this being our first to meet in person since before the pandemic began - justifying resources used/commitment given to make it work.
This year also, partly as an aid to help social distancing at the events, we used a new venue which had the added benefit of giving greater possibilities to improve and develop international collaboration amongst researchers, one of the charity's continuing and abiding objectives.
In this we feel we were very successful.
Many new collaborations were formed - one of the advantages of focusing efforts on getting the right people together in a productive atmosphere.
Many of these collaborations may not come to fruition for a while but they were, nevertheless, generated by the ability to meet in pleasant surroundings and inspired with the atmosphere of this international meeting. As one good friend and BRMEC13 delegate commented -
‘the agenda, speakers you chose, networking you encouraged & every detail helped us all meet new collaborators & have more hope that things are getting closer to answers’
