Lyme disease bacteria take cover in lymph nodes, study finds
See UC DAVIS news and info here
Barthold and co authors once again publish research that puts IDSA Cabal of Lyme denialists opinions into serious question. Time they bowed out and let the real science take over.
The bacteria that cause Lyme disease, one of the most important emerging diseases in the United States, appear to hide out in the lymph nodes, triggering a significant immune response, but one that is not strong enough to rout the infection, report researchers at the University of California, Davis.
“Overall, these findings suggest that B. burgdorferi hinder the immune system from generating a response that is fully functional and that can persist and protect after repeat infections,” Baumgarth said. “Thus, the study might explain why people living in endemic areas can be repeatedly infected with these disease-causing spirochetes.”
Lymphoadenopathy during Lyme Borreliosis Is Caused by Spirochete Migration-Induced Specific B Cell Activation
Acute Lyme Disease is one of the most important emerging diseases in the US.
People with acute Lyme disease often develop swollen lymph nodes, or lymphadenopathy, but we do not know why this happens or what effect it has on the course of the disease. We show here that when mice are infected with live Borrelia burgdorferi spirochetes (the bacteria that cause Lyme disease), live spirochetes collect in the lymph nodes. These lymph nodes then swell up and start producing large numbers of antibody-producing cells. Although many of these antibodies can recognize the bacteria, they apparently lack the quality to clear the infection. We hypothesize that by moving into the lymph node, usually a site in which strong immune responses are induced, Borrelia evades the immune response: it goes to the lymph nodes and tricks the immune system into making a very strong but inadequate response. here
This study is only on the acute phase of Lyme Disease but those of us who went on to develop Chronic Lyme Disease know from first hand experience how many Lymph nodes are involved and swollen.
