XMRV BINDS WITHIN THE CREB GENE..
OK WHAT DOES THAT MEAN
Mitochondria are our batteries that generate the power that our body systems need to operate properly
The easiest way to visualise the action of CREB is like a switch in a circuit.
If the switch is off even though the battery is fully charged no current can flow and no work can be done.Once the switch is turned on(CREB phosphorylated by ATP) the various biosystems in the body power up in a controlled way.
If one other other hand XMRV becomes integrated the switch can become faulty .This can cause "short circuits" or power cuts or turning on and off at the wrong times. It is a bit like every electric household item going crazy throwing sparks teely picture going on and off miccrowave bleeping etc
The other message to take from the paper is that CREB regulates the production of sterols.
The most commonly known sterol is cholesterol whose levels are frequently elevated in people with ME.Sterols are also the "reenforced concrete" of our cellular structures.
Defects in their production could theoretically end up with "Leaky" cell walls just about everywhere particularily in the gut.

XMRV BINDS WITHIN THE CREB GENE..
CBP enhances transcriptional activities via histone acetylation and the recruitment of additional co-activators such as SRC (steroid coactivator)-1 (r
The CBP protein (cAMP response element binding protein (CREB) binding protein) is a co-activator for several transcription factors with a wide range of important biological functions, such as sterol regulatory element binding proteins
This study demonstrates that CBP may function as a 'master-switch' between energy storage and expenditure.
