Allergy, Asthma, Autoimmunity Start the Same Way

Inflammation is the current medical buzzword. Name the disease and inflammation is there.

Reproduction Requires Controlled Inflammation
Aspirin blocks many of the steps in triggering inflammation and thus, aspirin administration can be used to reveal a role of inflammation in many unexpected places. Aspirin is effective in blocking some forms of infertility, inhibiting miscarriages and ameliorating postpartum depression. So inflammation is a critical part of reproduction. But, also notice that depression is a symptom of chronic inflammation.

Cancer Requires Inflammation
High dose (IV) aspirin has been successfully used to treat cancer. Inflammation is required for cancer growth, because both use the same transcription factor, NFkB. The aberrant signaling of cancer cells would normally lead to programed cell death, apoptosis, but inflammation blocks apoptosis. Aspirin can in turn block NFkB and in the absence of inflammation, cancer cells die by apoptosis.

Inflammation is Self-Limiting
Aspirin also transforms the COX/lipoxidase system to produce anti-inflammatory prostaglandins/eicosinoids. Inflammation normally progresses into anti-inflammation. Blocking this progression leads to chronic inflammation and a shift from local to systemic inflammation with the rise of inflammatory interleukins in the blood stream.

Immune Response Requires Inflammation
The signal molecules (IL-1, IL-6, TNF) and transcription factor, NFkB, associated with inflammation were all initially identified in the development of lymphocytes. Hence, IL stands for interleukin, a hormone that triggers leukocyte (literally white blood cells or cells associated with the lymphatic immune system, i.e. lymphocytes) development. The nuclear factor, i.e. transcription factor, involved in expression of the large chain, kappa, of immunoglobulins in B cells, was called NFkB.

Genes Expressed by NFkB Cause Symptoms of Inflammation
About five dozen genes are under control of NFkB. Among these are COX-2, the enzyme that converts omega-6 arachidonic acid to inflammatory prostaglandins; iNOS, the enzyme that produces nitric oxide that dilates blood vessels to produce hot, red skin; and the inflammatory interleukins, IL-1, IL-6 and TNF, associated with autoimmune disease, fatigue and cachexia (wasting).

Autoimmunity and Allergy Start with Inflammation
Medical treatments focus on symptom abatement and ignore cause. What causes obesity, allergy or autoimmune disease? The answer appears to be chronic systemic inflammation plus exposure to unusual proteins. The unusual proteins are immunogenic, i.e. interact with the immune system to produce antibodies or reactive T-cell receptors, and are subsequently recognized as autoantigens or allergens, that are the targets for immune attack. Inspection of these autoantigens and allergens shows that they all have one thing in common, they bind to heparin via a strong heparin-binding protein domain that is typically a triplet of adjacent basic amino acids.

Heparin is a Short, Highly Sulfated Fragment of Heparan Sulfate
Commercial heparin is purified from the intestines of hogs and cattle. Heparin is released from mast cells (made fluorescent for microscopy using berberine) along with histamine and is released into the intestines to block pathogens from binding to the heparan sulfate that is part of the intestine surface. The heparin is anti-inflammatory and it contributes to minimizing the inflammatory response of the intestines to food.

Inflammation Reduces Heparan Sulfate Production
Pathogen-generated inflammation of the intestines reduces heparan sulfate production and increases immune response to food antigens. NFkB activation by inflammation turns off the production of some genes needed for heparan sulfate proteoglycan (HSPG) synthesis. Since HSPG is a major component of the basement membrane that holds tissues together, the reduction of HSPG results in protein loss (proteinuria) from kidneys, leaking of intestines, and disruption of the blood/brain barrier.

Reduction of HSPG Results in Immunological Presentation of Autoantigens/Allergens
Proteins are brought into cells by specific binding to protein receptors. In many cases, particularly involving signaling or growth factors, both the signal molecules and the receptors bind to heparin. In addition, there is a robust circulation of HSPG, which is secreted and internalized with a half-life of approximately six hours. The sweep of the HSPGs take heparin-binding proteins with them for internalization, e.g. HIV-TAT, heparanase, tissue transglutaminase. I think that this HSPG sweep under inflammatory conditions also internalizes basic autoantigens and allergens with strong heparin-binding domains. This internalization is the first step toward immunological presentation and the immune response to autoantigens and allergens.

Autoantigen/autoantibody/HSPG Complexes Kill Cells
Antibodies against self-antigens, autoantigens form antigen/antibody complexes that also bind to and cross-link HSPGs, because of the heparin-binding domains of the autoantigens. The large complexes may disrupt HSPG circulation and trigger apoptosis or abnormal physiology. There are many other examples of heparin-based complexes that are toxic, e.g. Alzheimer’s amyloid plaque, diabetic beta cell antibody complexes, celiac gluten/tRG antibody complexes, multiple sclerosis myelin antibody complexes, atherosclerotic plaque.

Anti-Inflammatory Diet and Lifestyle Protects
Dietary and lifestyle adjustments that minimize inflammation, e.g. low starch, no HFCS, low vegetable oil (except olive) and supplements of vitamins D & C, fish oil (omega-3) and glucosamine, reduce the risk of allergies/asthma, degenerative diseases and cancers. Simple, high level supplements with fish oil reduce numerous mental disorders, e.g. depression, ADHD; infertility, pre-eclampsia and postpartum depression; allergies, asthma; arthritis, atherosclerosis; burn recovery, septicemia and head injury.

Reducing Inflammation is a Panacea for Modern Diseases
Most modern diseases have an inflammatory component, because modern diets are rich in inflammatory components, e.g. starch/sugar, corn/soy oil, HFCS, trans fats, and exercise is minimal. The medical industry has not successfully promoted healthy eating and exercise; and in fact has promoted the devastating replacement of saturated fats with inflammatory polyunsaturated vegetable oils. Meat production has moved away from grazing on omega-3-rich plant vegetation to omega-6-rich corn and soy. Replacement of the corn/soy based agricultural economy would have predictably immense beneficial impact in reducing inflammation-based degenerative autoimmune diseases and cancers.

Asthma Nitric Oxide

Arginine is the source of nitric oxide using the enzyme NOS. Inducible NOS is expressed in response to triggers of inflammation mediated by NFkB. NO in turn activates guanylate cyclase to increase cyclic GMP and cGMP relaxes muscle actin and myosin.

Studies are being made to assess the status of asthma by measuring nitric oxide (NO) in respired air. Since NO is produced as a product of the action of induced nitric oxide synthase (iNOS), and iNOS is synthesized when the inflammatory transcription factor NFkB is activated, then the inflammation that is a characteristic of asthma should be signaled by the production of NO.

If NO is involved in asthma, then one would expect relaxation of muscle to occur. That is the opposite of what is observed; contraction of the muscle cells surrounding airways is responsible for airway constriction is asthmatic episodes. Thus, during asthmatic episodes NO must be reduced.

Since NO is made from the amino acid arginine, then the ability to produce NO can be decreased by reducing available arginine. Arginine can be reduced by the enzyme arginase. The product is ornitine that can in turn be converted into purtrescine, the simplest of the polyamines that are used as counterions in the secretion of heparan and chondroitin sulfates.

Arginase is produced in high levels in asthmatics, but not in normal lungs. Also elevated putrescine is found in asthmatic lungs, indicating that arginine is being converted by arginase into ornithine and on to purtrescine. Ornithine is the precursor for proline that is a key amino acid in collagen production and the increased extracellular matrix that thickens the tissue of asthmatic lungs is rich in collagen.

A major point of this discussion is that NO can only be effectively lowered if there is a limited supply of arginine. Thus arginine supplementation should be helpful to asthmatics. Nitroglycerine patches may also be a means of enhancing sources of NO. Another possible approach would be the use of NO donors conjugated to NSAIDS. These conjugates delivered in an atomized form could provide the lungs with both NO and anti-inflammatory agents. Asthmatics also respond well to rigorous application of the anti-inflamatory diet and lifestyle.
