Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

2.3K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Regulation of Angiogenesis and Blood Supply

3.0K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

8.2K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

3.7K
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...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Ophthalmology

Background:

  • Bone morphogenetic proteins (BMPs) are vital for bone formation, repair, and vascular homeostasis.
  • Elevated BMP levels are linked to cardiovascular issues in diabetes mellitus.
  • The specific role of BMPs in diabetic retinopathy (DR) pathogenesis remains under-investigated.

Purpose of the Study:

  • To discuss the biological functions and mechanisms of BMPs.
  • To explore the potential role of BMP signaling in the pathogenesis of diabetic retinopathy (DR).
  • To highlight BMP signaling as a therapeutic target for microvascular dysfunction in DR.

Main Methods:

  • Literature review of existing studies on BMPs.
  • Analysis of evidence linking BMP signaling to retinal diseases like DR and age-related macular degeneration (AMD).
  • Discussion of potential therapeutic strategies targeting BMP signaling.

Main Results:

  • BMP signaling is implicated in retinal inflammation, hyperpermeability, and neovascularization in DR and AMD.
  • Evidence suggests BMPs play a significant role in the microvascular complications of diabetes.

Conclusions:

  • BMP signaling is a key factor in the pathogenesis of diabetic retinopathy.
  • Targeting BMP signaling presents a promising therapeutic avenue for treating microvascular dysfunction in DR.
  • Further research is warranted to fully elucidate BMPs' role in retinal diseases.
