Could naltrexone uncouple the autoimmunity caused by cross-targeting by blocking tlr-4? is tlr-4 the issue?

Cross-targeting is when 2 infections in the same place triggers autoimmune disease. A virus marking the inside of the target and an infection like a bacteria, mycobacteria, fungus, or mycoplasma marking the outside of the target. This is my hypothesis and I am looking into how this would involve tlr-4. ( this may not be the only overlap )

cytokine storm and autoimmune? does the overlap of infections cause some degree of this?

cytokine storm and flu

TLR-4 activates 2 pathways the myD88 which leads to inflammation cytokines and the TRIF-dependent side.
The TRIF-dependent side is involved with E.coli infections. 
Note that the Bird (avian) flu involves the myD88 pathway. 

If they are both going though the same TLR-4 the response could be amplified.  At what point does the immune system lose control? here?
