Summary
Intercellular Adhesion Molecule-1 (ICAM-1) is crucial for leukocyte movement during inflammation. Soluble ICAM-1 levels in bodily fluids indicate its role in various infectious, autoimmune, and proliferative diseases.
Area of Science:
- Immunology
- Cell Biology
- Molecular Medicine
Context:
- Intercellular Adhesion Molecule-1 (ICAM-1) is an immunoglobulin-like cell surface protein.
- ICAM-1 mediates leukocyte adhesion and migration to inflammatory sites.
- Expressed on endothelial cells and immune cells, ICAM-1 has both membrane-bound and soluble forms.
Purpose:
- To elucidate the role of ICAM-1 in disease pathogenesis.
- To highlight the clinical significance of ICAM-1.
- To review the involvement of soluble ICAM-1 in various disease states.
Summary:
- ICAM-1 is expressed on various cell types and is vital for leukocyte trafficking in inflammation.
- Soluble ICAM-1 is detectable in serum and cerebrospinal fluid.
- Elevated soluble ICAM-1 is associated with infectious, autoimmune, and proliferative diseases.
Impact:

01:16Calmodulin-dependent Signaling
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

01:25Structure 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...
01:20Cell 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).

01:31Immunoglobulin-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...

01:28Cryo-electron Microscopy
Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...
