Insights

Claudins (CLDNs), proteins crucial for cell barriers, are implicated in diseases and viral infections. Targeting CLDNs with antibodies shows promise for drug development and enhancing drug absorption.

Area of Science:

  • Cell biology
  • Immunology
  • Drug discovery

Background:

  • Claudins (CLDNs) are integral membrane proteins forming tight junctions essential for cellular polarity and barrier function.
  • Dysregulation of CLDNs is linked to diseases like cancer and inflammation, and some serve as co-receptors for viruses such as Hepatitis C.
  • The ability to modulate CLDN-mediated seals presents opportunities for improving drug absorption, making CLDNs significant therapeutic targets.

Purpose of the Study:

  • To review recent advancements in the development of anti-CLDN antibodies.
  • To discuss the potential of CLDNs as targets for novel drug development strategies.

Main Methods:

  • Literature review of recent research on CLDN antibody development.
  • Analysis of CLDNs' role in disease and drug delivery.

Main Results:

  • Development of monoclonal antibodies targeting extracellular CLDN domains is a key therapeutic strategy.
  • Progress in anti-CLDN antibody creation has faced delays but remains a focus area.

Conclusions:

  • CLDNs are promising targets for therapeutic intervention due to their role in barrier function and disease.
  • Further development of anti-CLDN antibodies is crucial for realizing their potential in treating various conditions and enhancing drug delivery.

Tight Junctions01:29

Tight Junctions

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...

Antibody Actions

Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...

Transcytosis of IgG01:15

Transcytosis of IgG

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...
