Insights

Enterovirus (EV) infection in children with type 1 diabetes (T1D) significantly reduces antioxidant enzyme activity. This decrease in enzymes like GPx, SOD, and CAT may worsen beta cell damage and inflammation in T1D patients.

Area of Science:

  • Endocrinology
  • Virology
  • Immunology

Background:

  • Type 1 diabetes (T1D) is an autoimmune disease affecting beta cells.
  • Enterovirus (EV) infections are common in children and have been implicated in T1D pathogenesis.
  • Antioxidant enzymes play a crucial role in protecting cells from oxidative stress.

Purpose of the Study:

  • To investigate the impact of Enterovirus (EV) infection on serum antioxidant enzyme activities in children with type 1 diabetes (T1D).
  • To compare enzyme activities between diabetic children with and without EV infection, and with healthy controls.

Main Methods:

  • Reverse transcriptase (RT)-PCR was used to detect EV RNA in 382 diabetic and 100 nondiabetic children.
  • Serum activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were measured.
  • Fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), C-peptide, and C-reactive protein (CRP) levels were assessed.

Main Results:

  • EV was detected in 26.2% of diabetic children versus 0% of controls.
  • Diabetic children had higher FBG, HbA1c, and CRP, and lower C-peptide than controls.
  • Antioxidant enzyme activities (GPx, SOD, CAT) were significantly lower in diabetic children compared to controls.
  • EV-infected diabetic children (T1D-EV+) showed further significant reductions in antioxidant enzyme activities compared to non-infected diabetic children (T1D-EV-).

Conclusions:

  • Enterovirus infection is associated with decreased serum antioxidant enzyme activity in children with type 1 diabetes.
  • Reduced antioxidant capacity in T1D-EV+ children may contribute to beta cell damage and increased inflammation.
  • Further research is warranted to explore the therapeutic potential of antioxidants in T1D management.

Enzymes and Activation Energy

The activation energy (or free energy of activation), abbreviated as Ea, is the small amount of energy input necessary for all chemical reactions to occur. During chemical reactions, certain chemical bonds break, and new ones form. For example, when a glucose molecule breaks down, bonds between the molecule's carbon atoms break. Since these are energy-storing bonds, they release energy when broken. However, the molecule must be somewhat contorted to get into a state that allows the bonds to...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Enzymes02:34

Enzymes

Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

Enzyme Kinetics01:19

Enzyme Kinetics

Enzymes speed up reactions by lowering the activation energy of the reactants. The speed at which the enzyme turns reactants into products is called the rate of reaction. Several factors impact the rate of reaction, including the number of available reactants. Enzyme kinetics is the study of how an enzyme changes the rate of a reaction.
Scientists typically study enzyme kinetics with a fixed amount of enzyme in the controlled environment of a test tube. When more reactant, or substrate, is...

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
