In another thread I posted a statement about
Bartonella being capable of turning off your immune system responses to itself and Lyme. This was challenged (rightly so) and so I started digging deeper.
As it turns out, Bartonella CAN mess with the immune system by secreting chemicals that turn off immunity and immune defense inflammation. There is a lipopolysaccharide produced by Bartonella which is a potent antagonist of Toll-like receptor 4 (TLR4). This Bartonella lipopolysaccharide is so powerful that it is being investigated as a potential treatment for autoimmune diseases. Here is the link to the medical journal article:
