Thank you for this interesting paper. PD very clearly has the features of an autoimmune disease and a few years ago we had discussions about it at the other forum. Its nice to see such "out of the box" ideas being experimentally proven. Auto immune responses, leaky BBB, role of vitamin D, Infections and inflammation and stress as contributing factors to PD are discussed here before they are experimentally proven in the labs. There may be many more, but these are a few I remember. And that says a lot about why patients' views and input are important in the pursuit of cure for PD.

Interesting. I know my WBC is always low (2.4 when it should be 4.5 to 10 approximately.) Low WBC indicates a weakened immune system.

It is very timely that you posted this article just a few days back. I was to the endocrinologist yesterday for my hypothyroidism that I have in addition to the PD. I have also been having the most irritated eyes in the past few months. Now he suspects I could have Sjogren's syndrome. Says it runs sometimes with people who have hypothyroidism. I have lots of allergies, borderline high blood sugar. Some kind of swelling and pain and spasms in my left foot, but no injury. The skin on my lower arms looks a little splotchy, almost like vitiligo. My mom had Rhematoid athritis,grandma diabetic, brain disorders in the family. Nephew with some sort of immune deficiency. All these things :)are autoimmune. So,, I got to thinking that my PD is likely the same. Anyone else here have some of these other disorders? It makes sense to me. Thanks FG

I have hypothyroidism, chronic sinusitis....

Forgive me going off topic, but one of the alleged benefits of coconut oil is improved thyroid function and it seems to be true. My wife (non-PWP) has long dealt with what seemed to be low thyroid function including being sensitive to cold temperature as well as a basal body temperature of 96.7 F.

After two months of the oil she has no problem with the room temperature and her body temp has risen a full degree. Also, she has lost 75% of the grey from her hair.

That is incredible, I think you mentioned it helped with anxiety/depression as well, so wonderful for her.

I was wondering, how much of the oil is she taking every day? One can only take so much of the stuff, healthy though it may be.

My first neuro thought I might have an autoimmune problem, especially when he found my biopsy from 1984 that diagnosed discoid lupus. I had several symptoms of systemic lupus, but my ANA was always negative.

I also have many allergies. My lupus resolved itself after a few years, don't know why. I wonder if osteoarthritis is autoimmune related, too.

And where do cytokines fit in?

What is the best kind of coconut oil to take, please?

Cytokine-induced immune deviation as a therapy for inflammatory autoimmune disease

The properties and outcome of an immune response are best predicted by the lymphokine phenotype of the responding T cells. Cytokines produced by CD4+ T helper type 1 (Th1) T cells mediate delayed type hypersensitivity (DTH) and inflammatory responses, whereas cytokines produced by Th2 T cells mediate helper T cell functions for antibody production.

To determine whether induction of Th2-like cells would modulate an inflammatory response, interleukin 4 (IL-4) was administered to animals with experimental allergic encephalomyelitis (EAE), a prototypic autoimmune disease produced by Th1-like T cells specific for myelin basic protein (MBP). IL-4 treatment resulted in amelioration of clinical disease, the induction of MBP-specific Th2 cells, diminished demyelination, and inhibition of the synthesis of inflammatory cytokines in the central nervous system (CNS).

Modulation of an immune response from one dominated by excessive activity of Th1- like T cells to one dominated by the protective cytokines produced by Th2-like T cells may have applicability to the therapy of certain human autoimmune diseases.

Cytokines and autoimmunity
John J. O'Shea1, Averil Ma2 & Peter Lipsky1 About the authors


Cytokines have crucial functions in the development, differentiation and regulation of immune cells. As a result, dysregulation of cytokine production or action is thought to have a central role in the development of autoimmunity and autoimmune disease. Some cytokines, such as interleukin-2, tumour-necrosis factor and interferons — ostensibly, the 'bad guys' in terms of disease pathogenesis — are well known for the promotion of immune and inflammatory responses. However, these cytokines also have crucial immunosuppressive functions and so, paradoxically, can also be 'good guys'. The balance between the pro-inflammatory and immunosuppressive functions of these well-known cytokines and the implications for the pathogenesis of autoimmune disease is the focus of this review.

"Emerging data indicate that, as the Dave Mason song goes, "there ain't no good guys, there ain't no bad guys", but rather a combination of cytokines exert variable effects at different times during the evolution of autoimmune disease. The complex role of cytokines in autoimmunity, especially their unanticipated immunosuppressive functions, is the focus of the this review. We have focused on interleukin-2 (IL-2), but will also draw on lessons learned from interferons (IFNs) and tumour-necrosis factor (TNF) to illustrate these points."

"In the neurodegenerative diseases Alzheimer disease and Parkinson disease, it has been difficult to identify the main target of the adaptive immune response. Instead, aspects of an innate immune response, including the presence of molecules of the MHC, complement components and cytokines such as TNF are present in the CNS67, 68. The lack of adaptive immunity in Alzheimer and Parkinson disease thus contrasts with its presence in diseases such as myasthenia, multiple sclerosis, Rasmussen encephalitis and stiff-man syndrome."

Distribution of major histocompatibility complex class II-positive microglia and cytokine profile of Parkinson's disease brains

Kazuhiro Imamura1 , Nozomi Hishikawa2

Abstract

There are numerous observations confirming that microglia expressing major histocompatibility complex (MHC) class II molecules are associated with the central nervous system (CNS) in aging and pathological conditions. In this study, we investigated the distribution of MHC class II-positive microglia in Parkinson''s disease (PD) brains.

The number of MHC class II-positive microglia in the substantia nigra (SN) and putamen increased as the neuronal degeneration of the SN proceeded. These cells were also ICAM-1 (CD54) and LFA-1 (CD11a) positive.

The number of activated microglia not only in the SN and putamen but also in the hippocampus, transentorhinal cortex, cingulate cortex and temporal cortex in PD was significantly higher than that in the normal control.

Most activated microglia persisted regardless of the presence or absence of Lewy bodies. They were frequently associated not only with -synuclein-positive Lewy neurites, but also with TH-16-positive dopaminergic and WH-3-positive serotonergic neurites, as well as MAP-2- and SMI-32-positive neurites.

These activated microglia were also positive for TNF- and interleukin-6, which are known to have a neuroprotective function. We conclude that MHC class II-positive microglia are a sensitive index of neuropathological change and are actively associated with damaged neurons and neurites.

First- She is taking a tablespoon each day.The brand is "Spectrum" and your local health food store should have it. It is one of the top brands for oils of all kinds. This one is labeled "Refined for medium high heat" and is mechanically extracted not chemically. It also comes in glass. Avoid fats packed in plastic like the plague. Fat soluble chemicals can stay in your body for a very long time.

I'm going back on the oil myself tomorrow but am going to start slow and try to gradually lessen the H. pylori factor. If anyone else experiments with it, please post your experience. I have been corresponding with Mary Newport, the MD whose husband was doing so well. She is presenting a paper this summer and would be glad to have the data.

ZF- the question of good guy - bad guy is a tough one and does indeed seem to change from day to day. Some of the language in those reports sound almost like endocrine feedback loops, only in the immune system.

That brings up an interesting thought. It is pretty evident to me that my controls of my endocrine system are out of whack. The endocrine system, in turn, serves as the control mechanism for other systems. If the immune system shows signs of a similar control circuit, maybe our whole mess stems from a general loss of calibration throughout our whole system? Hmmm?

Amazon (The Vitamin Shoppe) has the oil:

But this one has free shipping and is a good price:

Nutiva Organic Coconut Oil, 54-Ounce Jar

http://www.amazon.com/Nutiva-Organic-Coconut-Oil-54-Ounce/dp/B000GAT6NG/ref=pd_sim_hpc_5

Don't know if the jar is glass, though.

People use it on their skin too. And one for constipation, a PD problem!
It melts as 76 degrees F.

In South India,especially in Keralaa state, coconut oil is used as cooking oil. Coconut oil is used for body and hair in place of lotions and styling gels
In general, Keralites arae considered as healthy ppeople. Ayurvedic medicine is from that area.
I wonder if anyone actually done a comparative study of keralites with others related to PD. worth checking !

Girija-
Take a look at the full text at http://www.neurologyindia.com/article.asp?issn=0028-3886;year=2004;volume=52;issue=2;spage=213;epage=2 14;aulast=Jha

Here's the abstract-
A study was designed to generate epidemiological and clinical data on dementia, in a teaching hospital in India. It was conducted on 124 (94 male and 30 female) elderly patients (aged more than 60 years) presenting with clinical syndrome of dementia (DSM-3). Their age range was 64-78 (mean 65.7 4.1) years. Detailed clinical, biochemical, radiological and electrophysiological evaluation was done to establish etiology. Patients with psychiatric ailments, cranial trauma and tumors were excluded. The study period was 4.2 years. Multi-infarct dementia (MID) was observed to be commonest cause of dementia and was present in 59 (47.6%) cases. There were 10 (8%) patients each of tuberculosis (TB) and neurocysticercosis (NCC). Alcohol-related dementia was present in 13 (10.5%), while malnutrition (Vitamin B12 deficiency) was present in 9 (7.2%). Alzheimer's Disease (AD) was present (NINCDS-ADRDA criteria) in 6 patients (4.8%). There were 3 (2.4%) cases 1 each of Huntington's disease, Parkinson's and Normal Pressure Hydrocephalus and 2 each of diabetes, hypothyroidism, hyperthyroidism and Creutzfeldt' Jakob Disease. We conclude that AD, which is irreversible and common in the west, is relatively uncommon in India as compared to MID, infections and malnutrition, which are potentially treatable.
