From Innate To Adaptive Immunity In T2dm

Diabetes: Metabolic Syndrome

Experimental animal models of insulin resistance have demonstrated a Th2/Th1 shift in favour of Th1, shifting the Treg/Th17 shift towards Th17 and shifting the CD8/CD4 ratio in favour of CD8 and finally reduction of T-cell receptor diversity. These studies have recently been extrapolated to human subjects and confirm the observation that an increase pro-inflammatory stimuli causing M1 phenotype switching of adipose tissue macrophages result in the activation of a Th1 type response. IFN- and IL-17 produced by these T cell populations interact directly with adipocytes in addition to contributing to a pro-inflammatory loop in cells of innate immunity. IFN- inhibits the JAK-STAT pathway, and IL-17 induces the secretion of IL-6 from adipocytes. -cells isolated from T2D patients exhibit increased IL-8 and decreased IL-10 secretion. Recent studies regard the contribution of B-cell humoral immunity in adipose tissue inflammation. A study on experimental mice models involving B-cell knockout mice and anti-CD20 therapy showed a significantly improved metabolic phenotype and adipose tissue inflammation.

What Causes Metabolic Disorders

You can develop a metabolic disorder if certain organs for instance, the pancreas or the liver stop functioning properly. These kinds of disorders can be a result of genetics, a deficiency in a certain hormone or enzyme, consuming too much of certain foods, or a number of other factors.

There are hundreds of genetic metabolic disorders caused by mutations of single genes. These mutations can be passed down through generations of families. According to the

Diabetes is the most common metabolic disease. There are two types of diabetes:

  • Type 1, the cause of which is unknown, although there can be a genetic factor.
  • Type 2, which can be acquired, or potentially caused by genetic factors as well.

According to the American Diabetes Association, 30.3 million children and adults, or about 9.4 percent of the U.S. population have diabetes.

In type 1 diabetes, the T cells attack and kill beta cells in the pancreas, the cells that produce insulin. Over time, a lack of insulin can cause:

  • nerve and kidney damage
  • eyesight impairment
  • increased risk of heart and vascular disease

Hundreds of inborn errors in metabolism have been identified, and most are extremely rare. However, its estimated that IEM collectively affects 1 in every 1,000 infants. Many of these disorders can only be treated by limiting dietary intake of the substance or substances the body cannot process.

The more common types of nutritional and metabolic disorders include:

Triggering Of The Innate Immune System In T2d

Both TLR-dependent and TLR-independent mechanisms function in concert. This finding is demonstrated by animal models of diabetes in which there is partly protection of pro-inflammatory cytokine production in case of deficiency of TLR2 or TLR4, whereas deficiency of a universal intracellular docking protein MyD88 required for TLR signalling, exerted total protection. Apart from FFAs, systemic inflammatory responses are also elicited by elevated glucose levels. Sustained hyperglycemia results in non-enzymatic glycation of lipids and proteins resulting in the formation of AGEs. AGEs stimulate the pattern recognition receptor RAGE. Numerous cell types, like macrophages, T cells, smooth muscle cells, neuronal cells, podocytes and cardiomyocytes, express RAGE. RAGE activates the pleiotropic pro-inflammatory transcription factor NF-B along with stress kinases ERK1 and ERK2. Excessive glucose metabolized by oxidative phosphorylation to ATP results in ROS generation that tends to activate the NLRP3 inflammasome concomitantly with FFAs. This results in release of active IL-1 along with IL-1-dependent cytokine and chemokine production.

Connection Between Diabetes And Alzheimer’s Disease

What is metabolic syndrome? Are diabetics at risk?

Type 2 diabetes mellitus is characterized by high blood glucose levels resulting from increased hepatic glucose production, impaired insulin production by pancreatic cells, and insulin resistance, which closely resembles brain insulin resistance observed in AD patients. Furthermore, age-related alterations of mitochondrial function represent the driving force behind increased oxidative stress in T2DM contributing to the progression and development of AD pathology. T2DM and AD share common abnormalities including impaired glucose metabolism, increased oxidative stress, insulin resistance, and amyloidogenesis. Thus T2DM is a risk factor for AD .

More blood samples are then taken over the next 2 to 3 hours and are tested to determine whether the glucose in the blood rises to abnormally high levels.

Is Diabetes A Metabolic Disorder

Insulin is required to transport sugar from the blood in to the cells. This sugar undergoes various metabolic process in order to provide us energy as well as to store excess energy. This process of transferring glucose in producing and storing energy is said to be a metabolic process and any disorder altering this process is a metabolic disorder.

What Causes Metabolic Syndrome

Metabolic syndrome is more common in people who are overweight or obese. However, even if you are not obese, you may be at greater risk for metabolic syndrome if a parent or other close relative has type 2 diabetes.

Insulin resistance is another key cause of metabolic syndrome. When your cells resist insulin the hormone that regulate blood sugar levels you eventually accumulate too much sugar in your bloodstream. This increases your risk of metabolic syndrome, as well as prediabetes and type 2 diabetes.

Role Of Inflammation In Insulin Resistance

Metabolic syndrome

Insulin is a key endocrine hormone produced by -cells of pancreatic islets. Insulin is regarded as hormone of abundance owing to the array of functions it performs, the effects of which extend from metabolic to mitogenic activity .2). It is likely that disruption of insulin-mediated pathways will have pleiotropic effects that are not confined to carbohydrate metabolism only. Various mechanism working separately or in synergy have been linked to the development of insulin resistance among which chronic inflammation represents as a triggering point.

Various hormone functions of insulin.

Inflammation is an important component linking insulin resistance with nutrient overload and increased visceral adipocyte mass. During an insulin-sensitive state, the signalling cascade of insulin upon binding to its receptor results in phosphorylation of tyrosine residues of the insulin receptor substrate 1 ensuing in downstream insulin signalling. However, in an insulin-resistance state, pro-inflammatory molecules activate various other serine kinases like JNK, inhibitor of NFB kinase subunit , extracellular-signal regulated kinase , ribosomal protein S6 kinase , mammalian target of rapamycin , PKC and glycogen synthase kinase 3. The activation of these kinases inhibits insulin action by phosphorylating serine residues instead of tyrosine residues in the insulin signalling pathway.

Diabetes Mellitus And Metabolic Disorders

Diabetes mellitus is a group of metabolic disorders of carbohydrate metabolism characterized by high blood glucose levels and usually resulting from insufficient production of the hormone insulin or an ineffective response of cells to insulin . Secreted by the pancreas, insulin is required to transport blood glucose into cells. Diabetes is an important risk factor for cardiovascular disease, as well as a leading cause of adult blindness. Other long-term complications include kidney failure, nerve damage, and lower limb amputation due to impaired circulation.

Type 1 diabetes can occur at any age but often begins in late childhood with the pancreas failing to secrete adequate amounts of insulin. Type 1 diabetes has a strong genetic link, but most cases are the result of an autoimmune disorder, possibly set off by a viral infection, foreign protein, or environmental toxin. Although elevated blood sugar is an important feature of diabetes, sugar or carbohydrate in the diet is not the cause of the disease. Type 1 diabetes is managed by injections of insulin, along with small, regularly spaced meals and snacks that spread glucose intake throughout the day and minimize fluctuations in blood glucose.

Er Stress And Upr Pathways

What Is Diabetes Metabolic Syndrome?

Triggering of inflammatory signals by three pathways of UPR is initiated by activation of JNKs and NF-B in B cells. This activation acts as the linkage point between metabolic and immune pathways since the activation of these very kinases is analogous to that elicited by an immune response. JNKs play an important role in T2D, as increased activity has been shown to promote insulin resistance .

The first responses for opposing ER stress involve decreasing the translation of proteins. This involves phosphorylation of subunit of eIF2 by PERK. In humans and mice, loss of PERK expression is linked to dysregulation of the UPR response which is fundamental to ER stress, resulting in increased cell death and T2D. A permanent form of neonatal diabetes in humans is related to elevated ER stress markers as a result of a mutation in PERK, confirming the pivotal role of PERK in regulating ER stress during fetal development.

The third pathway of UPR involves the activation of ATF6, the basic leucine zipper domain protein, that upregulates PERK1 and IRE1 pathways by suppressing the apoptotic UPR signalling cascade under chronic ER stress. The role of ATF6 activation in -cell dysfunction has been concluded in studies that showed decreased expression of insulin gene by ER stress-induced ATF6 activation and a decrease in ER chaperones along with induction of apoptosis in ATF6 knockdown insulinoma cells.

Activation Of Inflammasome In T2d

Inflammasomes are multiprotein complexes in the intracellular machinery responsible for production of bioactive IL-1 in response to multiple stimuli. NLRP is a subfamily of Nod-like receptors containing a central nucleotide binding and oligomerization domain with flanking C-terminal leucine-rich repeats and N-terminal caspase recruitment or pyrin domains. The NOD-like receptor family, the pyrin domain containing 3 inflammasome is in a pathway that controls the production of IL-1 and IL-18. Unlike TLR, a potential role of NLR in metabolic abnormalities has not been extensively investigated. NLRP forms a constituent of the inflammasomes responsible for maturation and release of IL-1, and thus is a relevant candidate for metabolic disorders and T2D. NLRP3-dependent activation of inflammaosomes in diabetes was proposed by studies implicating the release of IL-1 as a consequence of elevated levels of glucose, FFAs and human islet amylopeptide . However, the effective metabolites involved in activation of inflammasomes are not clearly elucidated yet .

Activation of inflammasomes in type 2 diabetes into active IL-1. -cell-derived IL-1 promote the release of chemokines and recruitment of macrophages that are activated by human islet amyloid polypeptide, leading to deleterious concentrations of IL-1. FFA: Free fatty acid IL: Interleukin.

Antipsychotic Medications And Hyperglycemia

Case reports and retrospective database analyses suggest that conventional and atypical antipsychotics are associated with significant increases in fasting glucose concentrations. This hyperglycemia can result in new-onset type 2 diabetes, metabolic acidosis or ketosis, and even hyperglycemia-related deaths. Most cases of new-onset type 2 diabetes occur within the first 6 months of treatment and are often, although not always, associated with significant weight gain or obesity. A family history for diabetes is also associated with an increased risk.

There seems to be variability among the specific second-generation antipsychotics with respect to the incidence rates of diabetes. Koro et al., in a large population-based, case-control study, found the risk of diabetes associated with antipsychotics to be quite variable. Olanzapine had 4.2 times the risk associated with conventional agents and 5.8 times the risk associated with no treatment. Risperidone had 1.6 times the risk of conventional drugs and 2.2 times the risk of no treatment. Several large population retrospective studies have found that olanzapine and clozapine are associated with a significantly higher rate of diabetes than the conventional antipsychotics risperidone and quetiapine. The risk of diabetes,however, is higher with antipsychotic treatment use than in a general patient population sample.,,

Effect Of Renal Function And Insulin Sensitivity

The prevalence of the metabolic syndrome was 36% in patients with a creatinine clearance in the normal range, 34% in patients with a mild decrease in renal function, and 60% in patients with moderate to severe renal impairment . Patients with ESRD were excluded from the analysis. shows the relationship between insulin sensitivity, as assessed by eGDR and creatinine clearance at different stages of nephropathy. Most patients with type 1 diabetes and normal AER and renal function had normal insulin sensitivity. On the other hand, patients with microalbuminuria were more insulin resistant, whereas decreased renal function was most obvious in those with macroalbuminuria. When patients with normal AER were compared with those with microalbuminuria, there was only a small difference in creatinine clearance , whereas the difference in insulin sensitivity was large . When patients with microalbuminuria were compared with those with macroalbuminuria, there was a marked difference in creatinine clearance and a further decrease in insulin sensitivity .
