Onderzoek Kerr/Bansal

naar de relatie tussen

XMRV-infektie en NK-cel-afwijkingen gepland.

 

 

 

 


 

NK-cel-dysfunktie (wellicht in kombinatie met een verminderd aantal NK-cellen)

is in het verleden herhaaldelijk aangetoond bij ME/CVS-patiŽnten.

 

Kerr en Bansal zullen, gesponsord door ME Solutions en Invest in ME,

bestuderen of genen met afwijkende expressie (hogere of lagere eiwitproduktie)

bij patiŽnten die geÔnfekteerd zijn met het recent ontdekte XMRV-virius

gerelateerd zijn aan de werking (m.n. cytotoxiciteit) van NK-cellen.

 

PatiŽnten moeten niet alleen aan de nietszeggende Fukuda-kriteria voor CVS voldoen,

maar ook aan de empirisch ontwikkelde Canadese kriteria voor ME/CVS.

 

 


 

 

 

 

Funding Biomedical Research into ME

Two charities are joining forces to fund research into ME/CFS.

 

ME Solutions and Invest in ME are working together to maximise the opportunities to fund research into ME/CFS. The research project is -

 

The role of XMRV in modulation of NK cell cytotoxicity and NK cell gene abnormalities in ME/CFS patients and normal blood donors.

 

The project will be carried out by Dr Jonathan Kerr and his team from St. George's University, London, and Dr Amolak Bansal of the Department of Immunology, Epsom & St Helier University Hospitals NHS Trust.

 

 

Background to the project

 

A newly discovered γ-retrovirus, Xenotropic Murine Leukaemia Virus - like virus (XMRV) has recently been found to be present in the blood of 68 of 101 (67%) ME/CFS patients as compared with 8 of 218 (3.7%) normal healthy controls (Lombardi et al, 2009). XMRV has been cultured from T, B and NK cells, but primarily targets NK cells. NK cell dysfunction has previously been found to be abnormal in ME/CFS, despite their numbers often being largely unaffected.

 

Defects in the innate immune system are thought to play a key role in the pathogenesis of ME/CFS and these abnormalities may leave individuals susceptible to XMRV infection. This study will relate the presence of XMRV in NK cells with ME/CFS-associated abnormalities previously demonstrated in NK cells and ME/CFS-associated gene abnormalities.

 

Plan of Investigation

 

A sample of clinically-diagnosed (according to the Fukuda and Canadian criteria) ME/CFS patients and age-and-sex matched normal controls will be recruited. XMRV status will be determined and NK cells obtained and tested for ME/CFS-associated gene abnormalities in NK cells. XMRV status will be related to ME/CFS gene expression changes.
