Lipid-derived Compounds in the Human Body01:31

Lipid-derived Compounds in the Human Body

5.5K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various  biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...

Diabetic Retinopathy

66
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...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

859
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Asymmetric Lipid Bilayer01:35

Asymmetric Lipid Bilayer

8.1K
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...

Membrane Lipids01:32

Membrane Lipids

19.7K
Lipids are an essential component of all biological membranes. The average lipid content in mammalian membranes is 50%, though it can be as low as 20% in the inner mitochondrial membrane or as high as 80% in the myelin sheath present around the nerve cells.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

Area of Science:

  • Ophthalmology
  • Endocrinology
  • Molecular Biology

Background:

  • Diabetic retinopathy is a complication of diabetes characterized by abnormal blood vessel growth (angiogenesis).
  • Long-standing hyperglycemia in diabetes contributes to endothelial injury and pathological angiogenesis.
  • Reactive oxygen species (ROS) are implicated in the development of this angiogenesis.

Purpose of the Study:

  • To explore the role of reactive oxygen species (ROS) and vascular endothelial growth factor (VEGF) in diabetic retinopathy.
  • To understand the interplay between VEGF, ROS, and inflammatory mediators in the pathophysiology of diabetic retinopathy.

Main Methods:

  • Review of recent studies on the molecular mechanisms of diabetic retinopathy.
  • Analysis of the interaction between VEGF, ROS, pro-inflammatory and anti-inflammatory cytokines.
  • Investigation of the role of bioactive lipid mediators in the disease process.

Main Results:

  • Reactive oxygen species (ROS) play a significant role in the pathological angiogenesis seen in diabetic retinopathy.
  • Vascular endothelial growth factor (VEGF) is a critical angiogenic factor in this condition.
  • The interaction between VEGF, ROS, and inflammatory pathways is central to diabetic retinopathy.

Conclusions:

  • Understanding the interaction between VEGF, ROS, and inflammatory/anti-inflammatory molecules is crucial for deciphering diabetic retinopathy's pathophysiology.
  • These molecular interactions offer potential targets for future therapeutic interventions in diabetic retinopathy.
