During DMM 2006 we reported that chronic inflammatory disease, including much 'autoimmuneA condition or disease thought to arise from an overactive immune response of the body against substances and tissues normally present in the body' disease, was caused by an intraphagocytic biofilm A structured community of microorganisms encapsulated within a self-developed protective matrix and living together.-like microbiotaThe bacterial community which causes chronic diseases - one which almost certainly includes multiple species and bacterial forms.. Recovery followed activation of the VDRThe Vitamin D Receptor. A nuclear receptor located throughout the body that plays a key role in the innate immune response. with OlmesartanMedication taken regularly by patients on the Marshall Protocol for its ability to activate the Vitamin D Receptor. Also known by the trade name Benicar. , and long-term administration of subinhibitory antibiotics. Surprisingly, as the inflammatory disease disappeared from the subjects in that cohort, manifestations of comorbid neurological disease also receded. Memory and cognition returned as the inflammationThe complex biological response of vascular tissues to harmful stimuli such as pathogens or damaged cells. It is a protective attempt by the organism to remove the injurious stimuli as well as initiate the healing process for the tissue. waned, while suicidal ideation, depression, bipolar disorder, peripheral neuropathies and even obsessive compulsive disorder, receded. Additionally, we found that the neurological symptoms fluctuated with the level of ImmunopathologyA temporary increase in disease symptoms experienced by Marshall Protocol patients that results from the release of cytokines and endotoxins as disease-causing bacteria are killed. during the healing process, presenting special problems with cohort management. The VDR is at the heart of the innate immune system, responsible for expression of a majority of the body's antimicrobial peptidesBody’s naturally produced broad-spectrum antibacterials which target pathogens.1). Changes in lifestyle and medicine during the 20th century have created an environment favorable to the proliferation of pathogens which evade the immune system by suppressing activation of the VDR2). Kandel identified that short term memory involves activation of PKA3). We have determined that activation of PKA is regulated by the process of VDR homeostasis in chronic immune disease, pointing towards a putative mechanism whereby immune dysfunction can directly suppress short-term memory. However the above subjects not only reported the return of short term memory, but also of mid-term and long-term memory. The molecular mechanisms linking immune dysfunction and cognitive dysfunctionThe loss of intellectual functions such as reasoning; memory loss; and other neurological abilities that is severe enough to interfere with daily functioning. are clearly profound. We propose that studies of linked dysfunction will provide more insight than studies of neurological manifestations alone.
