Here we report the characterisation of one scFv (scFv173) antibody found to bind to the cell adhesion molecule CD166/ALCAM; a transmembrane glycoprotein member of the immunoglobulin superfamily.
The polymeric ligand we generated displays multiple copies of 3,6-disulfogalactose, and it can bind to the cell adhesion molecules P- and L-selectin.
The recruitment of neutrophils to a site of inflammation requires endothelial adhesion followed by transmigration and exit from the circulation, a process requiring the expression by neutrophils of integrins (e.g. CD11a/CD18 and CD11b/CB18) [ 55, 56], which then bind to endothelial cell adhesion molecules (e.g. ICAM-1 [ 57– 57]).
Third, lymphocytes and eosinophils may express α4 integrin, which binds to vascular cell adhesion molecule-1 (VCAM-1) on endothelium [ 218].
Genetic deletion and/or inhibitory antibody studies have shown that besides CX3CR1 [ 17], the patrolling behaviour of monocytes is also dependent on the integrin Lymphocyte Function-associated Antigen 1 (LFA-1;[ 16]), which binds to intercellular cell adhesion molecule-1 (ICAM-1) on endothelial cells [ 18].
To affect microtubule orientation and cell-to-cell adhesion, Rac1 binds to the actin-binding protein IQGAP1.
Thus, besides being crucial for cadherin-mediated cell-to-cell adhesion, β-catenin also binds to and activates the TCF/LEF-1 transcription factor, a key element in the Wnt signaling pathway [ 5, 21].
Galactose is a carbohydrate that is known to specifically bind to hepatocytes to promote cell adhesion and function via the ASGPR.
We thus concluded that LL-37 might bind to monosaccharides to prevent cell adhesion of C. albicans (Fig. 5C).
CYR61 (a member of the CNN family) has been shown to bind to integrin ανβ3 to mediate cell adhesion and migration (Kireeva et al., 1998) and CTGF may elicit its biological effects in a similar manner.
