Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Transcytosis of IgG01:15

Transcytosis of IgG

4.5K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Glucose Transporters01:27

Glucose Transporters

28.0K
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:

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Area of Science:

  • Immunology
  • Genetics
  • Medical Science

Background:

  • For two decades, genetic causes of immunoglobulin A deficiency (IgAD) were primarily attributed to chromosomal aberrations and the human major histocompatibility complex (MHC).
  • Emerging evidence indicates that monogenic disorders play a significant role in the pathogenesis of IgAD.

Purpose of the Study:

  • To review the concept of monogenic disorders in patients with IgA deficiency.
  • To identify the underlying pathogenic mechanisms contributing to IgA deficiency.

Main Methods:

  • Literature review of recent studies on genetic contributors to IgA deficiency.
  • Examination of the role of monogenic disorders in IgA deficiency development.

Main Results:

  • Recent studies suggest monogenic disorders are important genetic factors in IgA deficiency.
  • Identification of specific monogenic causes is crucial for understanding IgA deficiency.

Conclusions:

  • A clinical and immunologic evaluation, followed by targeted gene mutation analysis, is recommended for diagnosing IgA deficient patients.
  • Understanding monogenic causes offers a new paradigm for IgA deficiency research and clinical management.
