Yale researchers developed a controlled-release oral therapy that reversed type 2 diabetes and fatty liver disease in rats, according to a study published on Feb. In order to reverse the growing prevalence of T2DM it is imperative that the causes are identified and understood. However, before we examine the causes of T2DM in more detail it is important to consider the role genetics plays in the development of the disease.
Obesity is the leading cause of T2DM since most people with the condition are overweight or obese (Schuster, 2010). According to West (1978) excess calorie intake, which results in obesity, contributes more to the development of diabetes than any specific dietary component.
Smoking is strongly associated with a range of health issues, particularly coronary heart disease (Khan, Stewart, Davis, Harvey, & Leistikow, 2015). The causes of T2DM covered here are the strongest risk factors for developing T2DM even though there are many other risk factors for the disease.

Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system.[1][2] The disease typically presents between the ages of 20 and 40 and impacts approximately 35,000 individuals in the United States alone. There is a north to south gradient in MS disease prevalence on the Northern hemisphere and the opposite for the southern hemisphere. Bystander activation is a second mechanism that may explain the infectious agent’s role in MS. Activated complement products also induce antibody opsonization of myelin and Macrophage uptake.
Activated CD8+ T cells lead to oligodendrocyte apoptosis and neural cell death by destroying specific receptors on oligodendrocytes.
The activity of phagocytes produces large amounts of toxic reactive oxygen and nitrogen intermediates, including the free radical nitric oxide. Glutamate production is increased while destruction and re-uptake is decreased leading to oligodendrocyte excitotoxicity. Increased mitochondrial activity also correlates with increased reactive oxygen species (ROS) production.
Increased oxidative and nitrative stress in MS also results in production of reactive nitrogen species (RNS). Another trademark of MS is impaired apoptosis of auto-reactive T cells, B cells, and marcophages in the periphery, which eventually cross the blood brain barrier into the CNS. The following chart explains in detail the cellular components involved in the Multiple Sclerosis cascade, as briefly described above. Cell markers are present on the surface of all cells known as Major histocompatibility complex (MHC) proteins.
Hypothalamo-pituitary-adrenal (HPA) axis: this neuroendocrine axis is controlled by the hypothalamus, which receives input from higher cortical areas and other brain regions, including the limbic system. Studies using the EAE model of MS have shown that the HPA hyporesponsiveness to inflammatory stimuli predicts a more severe disease course. Macrophages take up an unknown foreign substance and present the antigen to T-cells in the blood or lymph nodes, and activation and expansion of the T-cells occur. The recognition of self-antigens at intermediate levels of affinity by T cells leads to positive selection and export of these T cells to the periphery.
Activated CD4+ cells can transfer EAE in vitro and arguments have been made for its occurrence in vivo. TH1 cells are a type of CD4+ T cell that produce interferon gamma (IF-?) and IL-2 to maintain an effective immune response.
Dysregulation of TH1 levels has been associated with autoimmune inflammation,[14] such as with MS. TH2 cells and its cytokines increase B cell proliferation, differentiation, and antibody production.
Dysregulation of T17 levels has been associated with autoimmune inflammation,[14] such as in MS.
Cytokines are cell-signaling polypeptides that are responsible for inter and intra-cellular communication. Increased levels of B cells have been identified in the CSF and CNS lesions in patients with MS. Monocytes enter the CNS through the blood brain barrier and differentiate to macrophages, which produce TNF-a at the inflamed site. An anti-inflammatory cytokine that is produced by Macrophages, Monocytes, B cells and Th2 cells.
A cytokine that provides immunity against intracellular pathogens and controls tumor formation.
Tumor necrosis factor-alpha (TNF-A) is an inflammatory cytokine with similar functions as IL-1. Auto-antibodies are antibodies produced by the body after the immune systems fails to recognize the body’s cells and tissues. Eosinophils are granulocytes cells produced in bone marrow that circulate to damaged tissue in response to inflammation. There are several types of excitotoxic factors but glutamate is one of the most important in cellular function. Glial cells are non neural cells found in the CNS that provide support, structure, and maintain homeostasis. NK cells are a main component of innate immunity through both effector and regulatory functions by means of their cytotoxic activity against tumor cells and virally infected cells. PLP has been shown to have more significant encephalogenic properties than MBP in some EAE models and is considered to be the main target of activated T cells. MBP is the second most abundant protein in myelin, found on the intracellular surface of the membrane. MBP has been extensively studied in EAE models, showing ability to induce EAE in mouse, rat, and nonhuman primates.
The third most abundant protein found in myelin in the CNS, possibly involved in its maintenance. A large glycoprotein found on the outer surface of the oligodendrocyte membrane in the CNS. Due to its location, MOG is highly accessible to antibodies and has been thought to be a target of immune responses in MS.
Reactive oxygen species (ROS) is a collective term that includes chemically-reactive molecules containing oxygen such as oxygen radicals, such as superoxide (O2), hydroxyl (OH ), peroxyl (RO2 ), and hydroperoxyl (HO2) radicals, and certain nonradical oxidizing agents, such as hydrogen peroxide (H2O2), hypochlorous acid (HOCl), and ozone (O3), that can be converted easily to radicals.[39][40] The signature unpaired electrons make these species highly reactive. Reactive nitrogen species (RNS) are a family of molecules derived from nitric oxide and superoxide.
Protease refers to a group of enzymes that hydrolyze the peptide bonds that link amino acids together in proteins. May be responsible for axonal degeneration as a result of axons undergoing changes to restore impulse conduction after demyelination via redistribution of sodium channels along the axons. Perforin is a pore forming protein found in most natural killer cells and cytotoxic T-cells. Transforming Growth Factor-beta (TGF-beta) is a growth factor that is part of the tissue repair response and is responsible for regulating the number of cellular reactions involved in the inflammatory response. In EAE, when TGF-beta is administered peripherally, it has been shown to play a role in the down-regulation of the immune response. There are two main forms of MS; relapsing-remitting (RR)-MS and secondary-progressive (SP)-MS.
It is important to first understand that the disease course for an individual with MS is diverse and variable.


MS is typically not a fatal disease; survival in MS is only marginally shortened by 5–7 years compared with general population in Western countries. Pregnancy is a disease modifying factor of MS but it does not have a negative effect on the course of MS.
Post-mortem research has shown that increased cortical demyelination is most commonly associated with progressive MS. 26 by Science.Existing therapies for type 2 diabetes, and the closely associated conditions of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), have had limited success at treating the root causes of these diseases. It appears that there are many risk factors for T2DM and that it is an insidious disease with subtle symptoms often developing over many years (U.S. Since insulin resistance (IR) is the major predictor of T2DM (Shanik et al., 2008), a lack of physical activity is a leading cause of T2DM.
However, a high fat intake is also strongly associated with the development of T2DM (Howard, 2000).
There is also research showing that smoking increase T2DM risk in a dose-dependent manner (Manson, Ajani, Liu, Nathan, & Hennekens, 2000).
However, the good news is that they are all modifiable lifestyle habits that may be easily changed by simply making a decision and taking action. Therefore, if you want to cure type 2 diabetes then you must be willing to change your lifestyle and most most people this means dramatic lifestyle changes!

Glucose Levels Normal Range For Gestational weight loss for diabetes type 1 mellitus diagnosekriterien type 1 Diabetes Kemh Gestational research has shown that tight blood sugar control reduces the risk of microalbuminuria by one third. Type 1 diabetes is an autoimmune disease that accounts for five- to 10-percent of all diagnosed cases (PDN) is a significant cause of pain and distress in patients with diabetes mellitus (DM). We see patients of diabetes mellitus tcc stearate magnesium all ages and our goal is to al dente pasta diabetes microbiota gut obesity provide you with the most comfortable office experience possible. Human herpesvirus 6 (HHV-6) and Epstein-Barr virus (EBV) have been most strongly implicated as both have been shown to be present at a high rate in people with MS, at 80% and 90% respectively.[1] HHV-6 demonstrates features similar to MS as it tends to induce repeated infections. During thymic selection, the T cells recognize the self-antigens, are positively selected, and are moved to the periphery. During infection, proinflammatory cytokines and chemokines are produced and may activate CD8+ T cells. However, the initial important event in MS occurs when autoreactive CD4+ T helper cells are activated in the periphery.
Following reactivation, CD4+ T cells release proinflammatory cytokines (IFN-gamma, TNF-alpha) and a variety of chemokines.
Following the response, stretches of axons are left demyelinated, oligodendrocytes are left damaged, and in some areas axon transsection is present. Disease can alter the function of the mitochondria and therefore alter the energy production of the tissue involved.
Stressed mitochondria increase production of nitric oxide (NO), which reacts with superoxide to form RNS peroxynitrite. There are 6 specific markers commonly known as human leukocytic antigens (HLA’s); HLA-A, HLA-B, HLA-C, referred to as class I antigens, and HLA-DP, HLA-DQ, and HLA-DR, referred to as class II antigens. This region is noted to contain the most genes in the human genome and encodes the most proteins known currently. However, most clinical studies indicate a hyperactive HPA axis in MS, particularly in the progressive stages of the disease.
The activated T-cells display adhesion molecules that allow attachment to and entry through the endothelial lining of the blood-brain barrier. Crossreactivity of these potentially self-reactive T cells with foreign antigens can lead to activation during infection, migration across the blood-brain barrier, CNS infiltration, and, if they recognize antigens expressed in the brain, tissue damage and potentially an autoimmune disease such as MS.
Normal mature T cells carry a surface protein called CD4+ and act to defend against pathogenic infections. MS is considered a CD4+ T cell mediated disease; however the exact role of CD4+ cells is much more complex and not fully understood. Clonal expansion has also been observed in the CSF of MS patients, along with the presence of oligoclonal Ig.[20] This data suggests there is an antigen-driven response in the CNS that leads to B cells producing a specific set of antibodies that produce oligoclonal banding.
They express cytokines including: TNF-alpha, IL-3, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, and IL-16.
It induces differentiation of CD4 helper T-cells and stimulates growth and differentiation of B cells. However, a review by Imitola et al.[18] concluded that a deficiency of IL-4 does not necessarily alter the disease course of EAE, but its’ upregulation may help reduce EAE severity. IFN-gamma either upregulates or downregulates Major Histocompatibility Complex (MHC) classes I and II. Through a cascade of events the auto-antibodies are synthesized to attack “self” proteins, leading to increased inflammation and cell death. Research has shown that auto-antibodies attached to neural tissues can elicit additional cell damage by increasing T-cells, monocytes, and eosinophils activity at the inflammation site.[27] Antibodies can also induce demyelination by increasing macrophage phagocytosis. A significant overlap of encephalogenic epitopes of MBP have been identified between rodent and human models, supporting the suggestion that MBP is highly involved in the human version of EAE: MS. Recent studies using EAE have shown MOBP may be a primary target of autoimmune T cells in MS.
While they are a natural byproduct of typical metabolism, they do have the potential to cause cellular damage to DNA, RNA, and proteins.[39] ROS can have negative effects on cell metabolism such as apoptosis, though it is also able to function to signal mobilization of ion transport and oxidative signaling. They are produced by neutrophils.[43] They work with reactive oxygen species and are harmful to cells particularly in the nervous system. They can break a specific peptide bond depending on the sequence of the amino acids, or break down a complete peptide chain. Due to the redistribution, ATP consumption is greatly increased and axonal ion concentrations may result in axon degeneration. Malignant MS occurs very rarely which typically refers to subjects who have frequent and disabling attacks with poor recovery. Cortical lesions and damage to adjacent white matter is evident by diffuse axonal injury relating to the whole brain and meninges.
Despite this, it appears that the type of fat consumed plays a role in the development of T2DM whereby a diet high in saturated fats and trans fatty acids increases the risk of T2DM, but monounsaturated fats and omega-3 polyunsaturated fats decrease the risk (Hu, 2000). The primary mechanism through which cigarette smoking contributes to T2DM is through the production of free radicals (Church & Pryor, 1985).

Type 1 diabetes is an autoimmune disease that accounts for five- to 10-percent of all diagnosed cases (PDN) is a significant cause of pain and distress in patients with diabetes mellitus (DM). Severe hypoglycemia signs and symptoms are almost always associated with diabetes drugs which can drive blood sugar too low.
Activated CD8+ T cells have been shown to specifically recognize viral antigens.[1] However, without the cooperation of several mechanisms autoimmunity is not induced, indicating the role of multiple factors to produce an autoimmune response as in MS. CD4+ T cells are activated in genetically inclined individuals due to a variety of causes detailed in the Viral and Bacterial Triggers and Environmental Factors section.
These cytokines can amplify local inflammation by activating microglia and astrocytes, which can induce myelin phagocytosis and cause increased reactivation of CD4+ cells.
Oligodendrocytes surviving the procress begin to re-myelinate damaged areas, however the original myelin thickness is not achieved again. Specifically, oxidative phosphorylation is affected, which can impair tissues that are dependent on high ATP supply such as the brain and nervous system.[7] The trademark of MS is damage to myelin sheaths and oligodentrocytes, which slows saltatory nerve conduction by increasing the size of the area where the axon continuously depolarizes.
The hormones secreted by the HPA axis have potent effects on immune function and other target tissues. A hyperactive axis can be associated with neurological disability, cognitive impairment and brain atrophy.


In MS, CD4+ cells contribute to CNS- and CSF-infiltrating inflammatory cells and are present at higher frequencies than normal.
The presence of unique Ig banding in individuals with MS has shown antibody specificities against components of myelin.[20]This includes MOG, MBP, and oligodendrocyte proteins.
Mast cells and its mediators are crucial components of the inflammatory response in humans. It also initiates the production of pro-inflammatory cytokines to increase macrophage activity. However, recent evidence has contradicted these findings and leads to questioning of IFN-gamma’s role in MS. It affects most organs in the body and serves a variety of functions based on its locations.
It also has some systemic actions that induce metabolic, hemodynamic, and hematologic alterations.
Most commonly, glutmate is packaged in vesicles in pre-synaptic axons and released into the synaptic cleft following input from a nerve impulse. Attack on this important protein may result in destabilization of the multi-layer myelin and lead to its breakdown. This protein’s role in MS has not been studied as extensively as PLP or MBP; however it has been seen in activated T cells in patients with the disease. They are released by platelets during wound healing to recruit additional platelets to the site of the injury.
They have been implicated as mediators of demyelination and axonal injury in both EAE and MS. RNS molecules participate as signaling molecules that regulate signaling pathways; they also modulate protein and lipid kinases and phosphatases, membrane receptors, ion channels, and transcription factors, including NF-?B.
Results from blocking NOS in EAE are not conclusive, and additional data suggest that it may even have an antiapoptotic effect or modulate immune responses and be beneficial.[1] Indirect evidence that reactive nitrogen species play a role in MS lesions includes the findings that proinflammatory cytokines including TNF have been identified in MS lesions.
The energy imbalance impairs the function of ATP-dependent ion chanels which leads to an increase in intracellular sodium concentrations. Currently, there are three types of cortical lesions: cortico-subcortical (affecting cortical and related white matter), intracortical, and subpial (affecting areas adjoined to the subarachnoid space).
T2DM is a major problem throughout the developed world and is the fastest growing chronic condition in Australia (Diabetes Australia, 2015). Moreover, it is important to distinguish between causes, risk factors, and determinants, especially as they relate to type 2 diabetes. Therefore, even though genetics may predispose a person to developing T2DM (Lyssenko et al., 2005), it does not guarantee the disease will develop. There are two mechanisms through which obesity contributes to T2DM, inflammation and oxidative stress.
Free radicals increase the amount of oxidative stress in the body and oxidative stress, as mentioned previously, causes dyregulation of adipokines. Predictors of and longitudinal changes in insulin sensitivity and secretion preceding onset of type 2 diabetes.

EBV has been shown to strongly predict MS and 100% of patients with MS are reportedly seropositive for the virus. While in the periphery activated CD4+ T cells increase the immune response by recruiting additional immune cells including: CD8+ cells, B cells, granulocytes, monocytes, and mast cells.
This process increases mitochondrial energy (ATP) production, decreases impulse velocity, and increases cellular demand for energy. Oligodendrocytes and myelin contain higher lipid content than most cells in the CNS, making them susceptible to ROS-induced damage and death. Autoreactive CD4+ cells have been shown to target various proteins, including MBP, PLP, MOBP, and MOG,[1] which are explained below. Once released into the cleft, glutamate binds to post-synaptic receptors, including NMDA receptors. This ultimately increases intracellular calcium and calcium dependent enzymes and damages the axon.
Grey matter lesions occur with less inflammation compared to white matter lesions, as evident by decreased macrophage and lymphocyte activity at the lesion sites. By definition, a cause is something or someone that produces an effect, result or condition (“Cause”, 2015), whereas a risk factor is a biological condition, behaviour or substance that has an association with, but has not been proven to cause, an event or disease (Rivkin & Bouwer, 2007). Adipocytes (fat cells) are metabolically-active cells and produce a range of hormones, adipokines and proinflammatory adipocytokines. Oxidative stress is also associated with inflammation, contributing to T2DM (Reuter, Gupta, Chaturvedi, & Aggarwal, 2010). The oligonucleotides bind to the mutant RNA and selectively induce its destruction in the nucleus by the enzyme RNase H. Follow your meal plan You will meet with a dietitian or diabetes educator who will help you design a meal plan full of Glucose Levels Normal Range For Gestational Diabetes Kemh Gestational healthy foods for you and your baby. It is a transporter hormone that moves glucose from the bloodstream into muscle tissue to be used as fuel thus promoting normal blood sugar levels. Furthermore, those who were infected with mononucleosis at a young age have a higher chance of developing MS. Another mechanism of bystander activation is the reaction of T cells to viral tissue damage, where the viral cells are recognized and killed. Activated CD4+ T and proinflammatory cells adhere to and then cross the blood brain barrier endothelium. The reduced supply of energy at damaged tissue has been shown to be associated with further tissue degeneration.
Despite this finding, critical axonal transection and neuronal damage is present within lesions. The proinflammatory adipocytokines induce insulin resistance on cell membranes by interfering with insulin signalling and action (Chen, Chen, Wang, & Liang, 2015). Moreover, the nicotine in cigarettes negatively affects insulin action in the body, leading to greater IR (Xie, Liu, Wu, & Wakui, 2009). Compared to high-GI foods sweet potatoes eak don more slowly in the body producing smaller fluctuations in blood glucose and insulin levels. This is due to the fact that in de-energized axonal areas sodium channels produce ectopic electrical potentials across the neuron, resulting in altered nerve communication. TNF is able to induce apoptotic cell death and inflammation, and it possesses both growth stimulating and growth inhibitory abilities.
Subpial cortical lesions are associated with follicle-like structures within the meninges containing B-cells and dendrite cells. Since T2DM has a latency period, it is difficult to establish exactly what a cause of the disease is. The proinflammatory adipocytokines also negatively affect the production and functioning of the adipokines, leptin and adiponectin, which improve insulin sensitivity (Bruun et al, 2003). A prospective study of cigarette smoking and the incidence of diabetes mellitus among US male physicians.
Limited ATP supply also alters ATP-dependent membrane channels and enzymes leading to increased intra-axonal Na+ and Ca2+. Nevertheless, by examining evidence it is possible to determine valid associations between risk factors and outcomes and that certain risk factors are ‘causal’ of outcomes (Boston University School of Public Health, 2015).
Moreover, central obesity may be a stronger predictor of T2DM than general obesity due to the higher levels of proinflammatory adipocytokines being produced by visceral adipose tissue (Samaras, Botelho, Chisholm, & Lord, 2010). The risk and burden of smoking related heart disease mortality among young people in the United States.
Therefore, in relation to T2DM there are risk factors that have demonstrated sufficient epidemiological evidence to indicate that they cause the disease.
