Summary
Researchers characterized novel epitopes on CD58 (lymphocyte function-associated antigen 3), a key molecule in T cell activation. This work provides new tools for studying CD58 interactions and T cell responses.
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- CD58 (lymphocyte function-associated antigen 3) is a crucial cell surface protein involved in T cell adhesion and activation.
- While the CD2 receptor's epitopes are well-defined, detailed functional characterization of CD58 epitopes is lacking.
Purpose of the Study:
- To identify and functionally characterize novel epitopes on the human CD58 molecule.
- To develop new monoclonal antibodies for detecting CD58 and its interactions.
Main Methods:
- Generation of a panel of murine monoclonal antibodies against recombinant human CD58.
- Epitope mapping and functional assays to assess CD58-CD2 interactions and T cell activation.
- Detection of CD58 in serum and on blood cells using newly developed antibodies.
Main Results:
- Six structurally and/or functionally distinct CD58 epitopes were identified.
- Two epitopes are functionally relevant for CD58-CD2 binding and T cell activation.
- New monoclonal antibodies enable detection of CD58 bound to CD2 in biological samples.
Conclusions:
- The study provides a comprehensive characterization of CD58 epitopes, revealing functionally important sites.
- Novel monoclonal antibodies offer improved tools for immunological research and diagnostics involving CD58 and T cell activation.

Structure of Cadherins
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
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).

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 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...

T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
