Glucose Transporters01:27

Glucose Transporters

15.2K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Hypersensitivities

7.2K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Drug Toxicity: Allergic Reactions

206
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Summary
This summary is machine-generated.

Many people avoid gluten due to non-celiac gluten sensitivity, but its prevalence and cause remain unclear. A study found about 3% of patients in gastroenterology care met criteria for this condition.

Area of Science:

  • Gastroenterology
  • Clinical Nutrition
  • Immunology

Background:

  • Non-celiac gluten sensitivity (NCGS) is increasingly reported, leading many to adopt gluten-free diets without a formal diagnosis.
  • The condition presents with symptoms after gluten ingestion, but without the established diagnostic markers for celiac disease or wheat allergy.
  • The role of gluten itself in NCGS and its classification as a distinct disease remain subjects of debate.

Purpose of the Study:

  • To determine the prevalence of non-celiac gluten sensitivity within a large cohort of patients attending secondary gastroenterology care.
  • To contribute to a better understanding of the clinical impact of gluten avoidance in the absence of other gluten-related disorders.

Main Methods:

  • A multicenter study involving over 12,000 patients in secondary gastroenterology care.
  • Patients were assessed based on specific criteria to identify those fulfilling the definition of non-celiac gluten sensitivity.

Main Results:

  • Approximately 3% of the studied patient population met the criteria for non-celiac gluten sensitivity.
  • This prevalence suggests a significant number of individuals may be experiencing symptoms attributed to gluten without a confirmed diagnosis.

Conclusions:

  • Non-celiac gluten sensitivity affects a notable percentage of patients in gastroenterology settings.
  • Further research is needed to establish stricter diagnostic criteria, develop reliable gluten challenge protocols, and elucidate the underlying pathogenesis.
