Caspases

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.

Acute Pancreatitis II: Pathophysiology

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...

The Proteasome

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Cytoskeletal Linker Proteins - Plakins

Cytoskeletal Linker Proteins - Plakins

Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Summary

This summary is machine-generated.

Calpains are implicated in cell degeneration and neurodegeneration. Specific calpain defects cause muscular dystrophy (LGMD-2A) and may contribute to type 2 diabetes, though mechanisms remain unclear.

Background:

Calpains, calcium-dependent proteases, are linked to cellular Ca2+ homeostasis dysfunctions.
Evidence increasingly supports the role of dimeric calpains in neurodegeneration.
Atypical calpains, calpain-3 and calpain 10, are associated with specific diseases.

Purpose of the Study:

To review the involvement of calpains in disease pathogenesis.
To highlight the known and unknown molecular mechanisms linking calpains to specific conditions.

Main Methods:

Review of existing scientific literature and genetic evidence.
Analysis of the molecular basis of calpain-related diseases.

Main Results:

Calpain defects are conclusively linked to Limb-Girdle Muscular Dystrophy type 2A (LGMD-2A) due to calpain-3 gene mutations.
Genetic evidence suggests calpain 10 involvement in type 2 diabetes etiology.
The precise molecular mechanisms for calpain-3 in LGMD-2A and calpain 10 in type 2 diabetes are currently unknown.

Conclusions:

Calpain-3 deficiency leads to LGMD-2A, but the underlying molecular pathology is not understood.
Calpain 10 is a potential factor in type 2 diabetes, requiring further mechanistic investigation.
Further research is needed to elucidate the roles of these atypical calpains in disease progression.
