Inflammation, Chronic Diseases and Cancer – 96 Cell and Molecular Biology, Immunology and Clinical Bases Taylor, P. Introduction Models of the inflammatory process depict scenes of a drama that has being studied for millenniums. A drama that began at the macroscopic level, with Celsus and the aphoristic comment “Vero notae inflammationis sunt quatuor: rubor et tumor cum calore et dolore"1 ; with the four cardinal signs of inflammation, followed by Virchow at the microscopic level by proposing a response to insult model, and one that continues to unfold as we develop molecular representations of this process, in an attempt to complete the story of a drama. Every form of inflammation with which we are acquainted, may be naturally explained in this way”. Rudolf Virchow 1858 It’s an open secret, and we continue to publish it as if it is a surprise or new knowledge even. Whether we realize it or not we have evolved a new field; a field that is defined by the intersection of immunology and hemostasis. Platelets whose main purpose has traditionally been considered as a plug forming device, is currently participating in new paradigms of disease, as a sophisticated mediator in a milieu of chemokines and adhesion molecules which modulate the immune response and consequently inflammation. Studies from 1 “But the signs of inflammation are four; redness, and swelling, with heat & pain“ 2 Inflammatory stimulus Inflammation, Chronic Diseases and Cancer – 98 Cell and Molecular Biology, Immunology and Clinical Bases inflammatory diseases such as sepsis, rheumatoid arthritis, and acute lung injury set the stage for modification of the thespian paradigm. One that helps us complete the continuum from coagulation to inflammation and back to coagulation again. No better model to appreciate the crosstalk between coagulation and inflammation than atherosclerosis. Platelets have a role early in the development of atherosclerosis Although platelets are not solely responsible for the development of atherosclerosis, their contribution to the inception of the vascular lesion, up until to atherothrombosis - its most critical consequence - is conceptually best understood as a model of inflammation. This is somewhat amusingly explained by Rudolf Virchow on a footnote in, Cellular Pathology (1865), “Suppose three people were sitting quietly on a bench, and suddenly a stone came and injured one of them, the others would be excited, not only by the sudden appearance of the stone, but also by the injury done to their companion, to whose help they would feel bound to hasten. Here the stone would be the irritant, the injury the irritament, the help an expression of the irritation called forth in the bystanders”. Virchow’s thought process, modern science not only has documented many different stones but also acknowledges that at times, these bystanders can hasten the irritament (inflammatory stimulus), therefore as we will understand an overzealous and excited bystander could prove to be, vessel hardening. If we look at atherosclerosis as a model of inflammatory disease, platelet adhesion could similarly be regarded as a model of platelet induced disease (Langer & Gawaz, 2008). Atherogenesis is influenced by platelets that adhere to activated vascular endothelial cells and feed chemotactic mediators to adjoining cells. Although the underlying mechanism of atherosclerosis is attributed to endothelial impairment due to insults from genetic and environmental factors (Lusis, 2000), it needs platelet firm adhesion to the endothelium for inception of the atheromatous plaque (Spagnoli et al. Genetic and environmental factors that trigger injurious events, which include the formation of reactive oxygen species, reduce the bioavailability of nitric oxide (Lowenstein et al. These two proteins allow the adhesion of platelets to the vascular endothelium in a multistep process. First platelets are tethered to the vascular wall with assistance by endothelial selectins. Depending on further activation of the endothelial cell and expression of endothelial integrins, the platelet adheres firmly to the vascular wall (May et al. Remarkably this can occur due to the fact that platelet activation is not required for platelet rolling (Harrison, 2005). In contrast, experimental models of mice infused with activated platelets also stimulate Weibel–Palade body exocytosis, promoting the development of atherosclerosis which is attributed to platelet P-selectin – mediated delivery of platelet-derived proinflammatory factors to monocytes/leukocytes and the vessel wall (Delvaeye & Conway, 2009). Major Receptor molecules in endothelium, platelet, and leukocyte interactions (Modified from Harrison, 2005) Inflammation, Chronic Diseases and Cancer – 100 Cell and Molecular Biology, Immunology and Clinical Bases Activated platelets propel inflammation, by forming platelet-leukocyte complexes which facilitate leukocyte migration into the arterial wall. Since the density of P-selectin on platelets after activation is much higher than on endothelium, leukocytes are easily recruited to the adherent activated platelets (White, 2007). In these dynamics, the balance between homeostasis and inflammation is easily shifted to inflammation in a vicious cycle as soluble P-selectin, shed from activated platelets and endothelium, stimulate leukocytes to produce tissue factor which subsequently activates more platelets (Vicic & Weiss, 1983). In further interaction with leukocytes; polymorphonuclear cells adhere to platelets in a Mac-1– dependent manner, inducing complex activation cascades in monocytes that promote monocyte or neutrophil adhesion, thrombosis, monocytic chemokine and cytokine release, or the oxidative burst of neutrophils (Rivera et al. By no means are platelets, endothelial cells and leukocytes innocent bystanders; through years of evolution these eager to protect cells fight infection, hemorrhage and constant insults. In the theater of inflammation, as it often happens, we undergo friendly fire, which make our vessels harder but not tougher.

Coeliac disease is_ not _a food allergy or intolerance. Since the symptoms of soy sensitivity can be delayed up to three days, it can be difficult to determine with a food diary if soy is the problem, or — more likely — part of the problem, since children who are sensitive to soy are also often sensitive to casein and gluten. Many children with ADHD and autism are sensitive to the proteins in wheat (gluten) and milk (casein) and benefit tremendously from a gluten-free, casein-free (GFCF) diet. E - Nonceliac gluten sensitivity is synonymous with wheat allergy. A - The diagnosis requires that both celiac disease and wheat allergy are first excluded. Common foods like wheat, eggs, rice and milk were cut out, and within a few weeks the joint pain had reduced to point of being hardly noticeable. OAS (oral allergy syndrome): OAS is a common name for having an allergic reaction to a food (ex.

Opinion of the scientific panel on dietetic products, nutrition and allergies on a request from the commission relating to the evaluation of allergenic foods for labeling purposes. This was aptly summarized by the consensus statement published after a conference of experts convened by the National Institutes of Health which noted that "The strict definition of a gluten-free diet remains controversial due to the lack of an accurate method to detect gluten in food products and the lack of scientific evidence for what constitutes a safe amount of gluten ingestion " (NIH, 2004). We are not aware of any prospective clinical trials that have examined the health of individuals with celiac disease on a gluten-free diet for more than a few months. The critical knowledge gap about individuals with celiac disease is whether chronic, low-level exposure to gluten in a gluten-free diet will cause any harm over a lifetime. Unlike food allergies, clinical signs and symptoms do not appear to be reliable markers of disease activity because many individuals affected with celiac disease may be entirely asymptomatic. The potential benefit of a gluten-free diet has not been established for individuals with silent or latent celiac disease. Despite the uncertainties associated with food challenge data from the literature, LOAELs from human clinical trials currently provide the best data for estimating population-based reactions to food allergens. If consumption of highly refined oils is not associated with allergic reactions, and if there is nothing unique about the proteins in highly refined oils, then consumption of another food containing levels of protein that result in an exposure that is equal to or less than the level in a typical serving of highly refined oils should not be associated with allergic reactions. The current draft proposal would define three categories of gluten-free foods: processed foods that are naturally "gluten-free" (≤ 20 ppm of gluten), products that had been rendered "gluten-free" by processing (≤ 200 ppm), and any mixture of the two (≤ 200 ppm). Although gluten-free diets are considered the only effective treatment for individuals with celiac disease, it has been recognized that it is difficult, if not impossible, to maintain a diet that is completely devoid of gluten (Collin et al., 2004). Catassi et al. (1993) reported that children, whose celiac disease had previously been controlled on gluten-free diet, had evidence of intestinal mucosal or immunological changes (changes in intraepithelial lymphocyte counts and the villous height to crypt depth ratio) following 100 mg or 500 mg of daily gliadin over 4 weeks; this corresponds to 200 mg and 1000 mg of daily gluten respectively (Collin et al., 2004). For single ingredient foods made from wheat, rye, barley, triticale, and oats, the simple presence of "protein" in that food may be used as an indicator that gluten proteins are present. There is substantial evidence that both prolamin proteins (i.e., gliadins) and glutelin proteins (i.e., glutenins) in wheat affect individuals with celiac disease (Shan et al., 2002; Hausch et al., 2002; Vader et al., 2002; van de Wal et al., 1999; Molberg et al., 2003). Celiac disease is caused by an immune response in genetically predisposed individuals to specific storage proteins, commonly referred to as "glutens," that occur naturally in cereal grains (Shan et al., 2002). There is a consensus opinion that celiac disease is caused by an aberrant (T lymphocyte) immune response to dietary glutens predominantly found in wheat, barley, and rye (NIH, 2004). Those with food intolerances may be able to tolerate eating small amounts of the food in question, while those with food allergies can have an extreme reaction from small amounts or even traces of the food that causes their allergy.
