Abstract
Chemokine (C-C motif) receptor 7 (CCR7) is a class A subtype G-Protein Coupled Receptor. It contributes to the migration and activation of dendritic cells, T cells, eosinophils, B cells and different cancer cells. CCR7 signalling system is involved in T cell activation, immune tolerance, inflammatory response and cancer metastasis. CCL19 and CCL21 are the two CCR7 ligands and are differential in their signalling through CCR7.
This study was to design a network CC- chemokine receptor 7 and understand the role of CCR7 using in silico tools.
The sequence of the ligand and the receptor has been extracted from GPCR database to understand the signalling system. The interacting 3D structure of CCR7-CCL19 and CCR7-CCL19 has been studied with 3did the database of three dimensional interacting domains (3did) to know the domain interaction. The interaction networks of GPCR and the ligands have been studied with STRING, an interaction database. The GPCR and the ligands have been modelled using Swiss Model. The network of the differential signalling of CCL19 and CCL21 with CCR7 has been visualized with the help of NetSlim. The modelled CCR7 were further docked with CCL19 and CCR7 in Hex.
