Matrix Proteoglycans and Glycoproteins01:21

Matrix Proteoglycans and Glycoproteins

5.1K
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the most common type of cartilage in the body, consists of short and dispersed collagen fibers associated with large amounts of proteoglycans. These proteoglycans have long negative charges that attract cations, which in turn attract water molecules. This influx of ions and water molecules swells up the proteoglycan like a water-soaked gel that can...

Chronic Pharyngitis01:23

Chronic Pharyngitis

11.9K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Chronic Pancreatitis I: Introduction

741
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

1.3K
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

802
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Area of Science:

  • Immunology
  • Pharmacology
  • Rhinology

Background:

  • Chronic rhinosinusitis (CRS) is a complex inflammatory condition with unclear pathogenesis and limited treatment options.
  • P-glycoprotein (P-gp), a known efflux pump in cancer, is implicated in CRS.

  • To discuss the potential of exosomal P-gp testing as a non-invasive biomarker for CRS.

Main Methods:

  • Literature review of current research on P-glycoprotein in CRS.
  • Analysis of P-gp's role in inflammatory pathways and T-cell polarization.
  • Evaluation of P-gp inhibition and exosomal P-gp testing as clinical tools.

Main Results:

  • P-glycoprotein (P-gp) is involved in the inflammatory processes of chronic rhinosinusitis (CRS).
  • P-gp inhibition presents a potential targeted therapy for specific CRS subtypes.
  • Exosomal P-gp levels may serve as a novel, non-invasive biomarker for CRS diagnosis and management.
