Insights

Glomerulosclerosis, or kidney scarring, is irreversible. Renin-angiotensin system inhibitors may slow its progression by protecting podocytes, crucial cells in the kidney filtration barrier.

Area of Science:

  • Nephrology
  • Renal Physiology
  • Pathology

Background:

  • Glomerulosclerosis involves irreversible kidney scarring, leading to end-stage renal disease.
  • Inhibitors of the renin-angiotensin system are used to slow chronic kidney disease progression.
  • Their mechanism may involve reducing intraglomerular pressure and shear stress on podocytes.

Purpose of the Study:

  • To confirm the role of podocyte adhesion in glomerular integrity.
  • To investigate the effect of renin-angiotensin system inhibition on glomerulosclerosis in specific animal models.

Main Methods:

  • Experimental models were used to assess podocyte adhesion.
  • The impact of renin-angiotensin system inhibition was evaluated in these models.

Main Results:

  • Experimental evidence confirmed the critical role of tight podocyte adhesion for glomerular integrity.
  • Renin-angiotensin system inhibition reduced glomerulosclerosis in animals with less adherent podocytes.

Conclusions:

  • Podocyte adhesion is vital for maintaining kidney health.
  • Reducing intraglomerular blood pressure via renin-angiotensin system inhibition offers a potential therapeutic strategy for glomerulosclerosis, especially when podocyte adhesion is compromised.

Adhesion01:14

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow glass...

Regulation of Angiogenesis and Blood Supply

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 hydroxylase and factor...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Tight Junctions01:29

Tight Junctions

Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in multicellular organisms. They are mainly composed of claudin and occludin transmembrane proteins, and other proteins such as tricellulin and JAM (junctional adhesion molecule). All these proteins are 4-pass transmembrane proteins, except JAM, which is a single-pass transmembrane protein belonging to the immunoglobulin superfamily. The...

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
CAM Families
The Integrin family of proteins is primarily  involved in a...

Tension Response at Adherens Junctions

The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
α-Catenin as a Mechanosensory Protein
The α-catenin of adherens junctions is an allosteric protein with three VH (vinculin homology) domains...
