Article Abstract
Atherosclerosis is one of the leading causes of mortality in developed and developing countries. The onset of atherosclerosis development is accompanied by overexpression of several inflammatory chemokines. Neutralization of these chemokines by chemokine-binding agents attenuates atherosclerosis progression. Here, we studied structural binding features of the tick protein Evasin-3 to chemokine (C-X-C motif) ligand (CXCL1). We showed that Evasin-3-bound CXCL1 is unable to activate the CXCR2 receptor, but retains affinity to glycosaminoglycans. This observation was exploited to detect inflammation by visualizing a group of closely related CXC-type chemokines deposited on cell walls in human endothelial cells and murine carotid arteries by a fluorescent Evasin-3 conjugate. This work highlights the applicability of tick-derived chemokine-binding conjugates as a platform for the development of new agents for inflammation imaging.

Surface plasmon resonance (SPR) is a widely utilized technique for measuring the kinetics of molecular interactions. However, in dynamic living systems, the kinetics of target-ligand interactions may differ. Additionally, most cellular assays rely on end-point measurements, lacking the ability to monitor cellular interactions in real-time.

Thiazolidine ring-opening reaction is one of the key steps in protein chemical synthesis via sequential native chemical ligation strategy. We recently developed a novel thiazolidine ring-opening reaction with 2,2'-dipyridyl disulfide (DPDS). In order to investigate the applicability of this reaction to glycoprotein synthesis, we synthesized evasin-3, a cysteine-rich glycoprotein with chemokine-binding ability originally found in tick saliva.

The display of recombinant proteins on bacterial surfaces is a developing research area with a wide range of potential biotechnological applications. The lactic acid bacterium is an attractive host for such surface display, and a promising vector for delivery of bioactive proteins. Surface-displayed recombinant proteins are usually anchored to the bacterial cell wall through anchoring domains.

Chemokines are a group of chemotaxis proteins that regulate cell trafficking and play important roles in immune responses and inflammation. Ticks are blood-sucking parasites that secrete numerous immune-modulatory agents in their saliva to evade host immune responses. Evasin-3 is a small salivary protein that belongs to a class of chemokine-binding proteins isolated from the brown dog tick, Evasin-3 has been shown to have a high affinity for chemokines CXCL1 and CXCL8 and to diminish inflammation in mice.
