Transcytosis of IgG01:15

Transcytosis of IgG

4.0K
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...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.1K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

4.1K
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Immunocytochemistry and Immunohistochemistry01:22

Immunocytochemistry and Immunohistochemistry

13.3K
Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.
These...

Tight Junctions01:29

Tight Junctions

6.8K
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...

GPCR Desensitization01:12

GPCR Desensitization

7.9K
G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...

Purpose of the Study:

  • To evaluate a vaccine candidate designed to target IgE.
  • To assess the vaccine's ability to induce inhibitory antibodies.
  • To investigate the impact of these antibodies on IgE-receptor interactions.

Main Methods:

  • Development of a novel vaccine candidate.
  • Immunization of subjects and collection of serum.
  • Assay development to measure antibody function.
  • Testing the ability of induced antibodies to inhibit IgE binding to granulocyte receptors.

Main Results:

  • The vaccine candidate successfully induced antibodies in subjects.
  • These antibodies demonstrated the ability to inhibit IgE binding to its receptor on granulocytes.
  • The inhibition was specific to the IgE-receptor interaction.

Conclusions:

  • The vaccine candidate is effective in generating antibodies that block IgE-receptor interactions.
  • This approach represents a potential new therapeutic strategy for allergic and other IgE-mediated diseases.
