Summary
Toll-like receptors (TLRs) are crucial for immune defense, interacting with other cell receptors. This review explores the significant crosstalk between TLRs and integrins, offering potential for immune function modulation.
Area of Science:
- Immunology
- Cell Biology
Background:
- The immune system identifies pathogens and antigens.
- Toll-like receptors (TLRs) are vital for initial pathogen defense, mediating cytokine and chemokine production.
- TLRs share signaling pathways with other receptors, leading to complex crosstalk influencing immune responses.
Purpose of the Study:
- To review the significant and complex crosstalk between Toll-like receptors (TLRs) and integrins.
- To understand how integrins influence TLR-mediated immune signaling.
- To explore the potential for modulating TLR functions through integrin interactions.
Main Methods:
- Literature review focusing on studies investigating the interplay between TLRs and integrins.
- Analysis of research describing synergistic or inhibitory interactions.
- Synthesis of findings on the functional consequences of this crosstalk.
Main Results:
- TLRs are key in innate immunity, triggering cytokine and chemokine release.
- Integrins, critical adhesion molecules, exhibit synergistic or inhibitory interplay with TLRs.
- This crosstalk significantly impacts the profiles of TLR-induced cytokines and chemokines.
Conclusions:
- The intricate crosstalk between TLRs and integrins is central to immune system regulation.
- Understanding this interaction is key to developing strategies for modulating TLR functions via integrins.
- Targeting the TLR-integrin axis may offer novel therapeutic approaches in immunology.

01:17Intracellular Signaling Affects Focal Adhesions
2.7K
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.

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,...

01:15Activation of Integrins
3.4K
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...

3.2K
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...

01:19Interactions Between Signaling Pathways
6.3K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

3.3K
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,...
