Insights

Normal human Langerhans cells bind IgE via three molecules: Fc epsilon R2/CD23, IgE-binding protein (epsilon BP), and Fc epsilon RI. Their roles in atopic disease are discussed.

Area of Science:

  • Immunology
  • Dermatology

Background:

  • Normal human Langerhans cells (LC) possess the ability to bind immunoglobulin E (IgE).
  • Understanding IgE-binding molecules on LC is crucial for investigating immune responses.

Purpose of the Study:

  • To review recent data on IgE-binding structures on human Langerhans cells.
  • To discuss the physiological relevance of these structures in the context of atopic disease.

Main Methods:

  • Characterization of IgE-binding molecules on normal human Langerhans cells.
  • Review of current scientific literature on Fc epsilon R2/CD23, epsilon BP, and Fc epsilon RI.

Main Results:

  • Three distinct IgE-binding structures identified on human Langerhans cells: Fc epsilon R2/CD23 (low affinity IgE receptor), IgE-binding protein (epsilon BP, homologous to murine Mac-2 antigen), and Fc epsilon RI (high affinity IgE receptor).

Conclusions:

  • These IgE-binding molecules on Langerhans cells may play a significant role in the pathogenesis of atopic diseases.
  • Further research into these interactions could lead to novel therapeutic strategies for atopic conditions.

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence the...

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
CAM Families
The Integrin family of proteins is primarily  involved in a...
Selectins01:25

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
Immunoglobulin-like Cell Adhesion Molecules01:31

Immunoglobulin-like Cell Adhesion Molecules

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...
Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
