Cell Specific Gene Expression01:58

Cell Specific Gene Expression

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
Diabetic Neuropathy01:22

Diabetic Neuropathy

DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
Glucose Homeostasis: Pancreatic Islets and Insulin Secretion01:27

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...
Glucagon-like Receptor Agonists01:24

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Diabetic Nephropathy01:28

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

Area of Science:

  • Neuroscience
  • Endocrinology
  • Metabolic Disorders

Background:

  • Diabetes mellitus and its complications are significant causes of morbidity and mortality, with rising incidence linked to lifestyle changes, obesity, and aging.
  • Diabetic encephalopathy, a severe microvascular complication, involves cognitive impairment and neurological abnormalities, potentially due to intracellular glucose's direct neuronal damage.
  • Pathogenesis is complex, involving metabolic alterations, vascular changes, and neuronal apoptosis, influenced by factors like the insulin growth factor (IGF) system, hyperglycemia, and aging.

Purpose of the Study:

  • To investigate the role of insulin/C-peptide deficiency in diabetic encephalopathy.
  • To evaluate the therapeutic potential of C-peptide in mitigating diabetic encephalopathy-related neuronal damage.

Main Methods:

  • Review of recent data and research findings on diabetic encephalopathy pathogenesis.
  • Analysis of the effects of C-peptide administration on the IGF system and neuronal apoptosis in the hippocampus of diabetic models or patients.

Main Results:

  • Recent data indicate that insulin/C-peptide deficiency may be a primary factor in diabetic encephalopathy.
  • C-peptide administration was shown to partially restore the IGF system in the brain.
  • C-peptide treatment effectively prevented neuronal apoptosis in the hippocampus of diabetic subjects.

Conclusions:

  • Insulin/C-peptide deficiency plays a key role in the development of diabetic encephalopathy.
  • C-peptide administration demonstrates therapeutic potential by improving brain IGF system function and reducing neuronal apoptosis.
  • C-peptide represents a promising therapeutic strategy for managing diabetes and its neurological complication, diabetic encephalopathy.
