Summary
Disintegrins, peptides from snake venom, modulate cell adhesion by interacting with integrins. They can block or activate integrin signaling, offering insights into immune responses and potential therapies.
Area of Science:
- Cell Biology
- Immunology
- Biochemistry
Background:
- Extracellular matrix proteins and integrins are crucial for cell adhesion, migration, and signaling pathways.
- Integrin signaling regulates leukocyte functions, including immune responses and inflammatory states.
- Disintegrins, from snake venom, bind to integrins via an RGD motif, influencing their functions.
Purpose of the Study:
- To review the dual role of disintegrins in modulating integrin-mediated signaling.
- To highlight the significance of disintegrins in understanding leukocyte behavior and immune regulation.
- To explore the therapeutic potential of disintegrins in interfering with integrin effects.
Main Methods:
- Literature review of studies on extracellular matrix proteins, integrins, and disintegrins.
- Analysis of signaling pathways regulated by integrin-extracellular matrix interactions.
- Examination of disintegrin's effects on integrin function in various cell systems.
Main Results:
- Disintegrins can act as antagonists or agonists of integrin signaling, depending on the cellular context.
- Integrin modulation by disintegrins impacts leukocyte adhesion, migration, and immune responses.
- Disintegrins serve as valuable tools for studying integrin signaling and developing targeted therapies.
Conclusions:
- Disintegrins offer a versatile platform for dissecting integrin-mediated cellular processes.
- Understanding disintegrin actions is key to developing novel therapeutic strategies for inflammatory and immune diseases.
- Disintegrins represent promising prototypes for drugs targeting integrin-related pathologies.

01:15Activation of Integrins
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.

01:17Intracellular Signaling Affects Focal Adhesions
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:10Integrins
Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:25Selectins
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...
01:26Acute Inflammation II: Cellular Phase
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
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...
