Structural basis of chemokine recognition by the class A3 tick evasin EVA‐ACA1001

Protein Science, Volume 33, Issue 6, June 2024.
Abstract Ticks produce chemokine‐binding proteins, known as evasins, in their saliva to subvert the host's immune response. Evasins bind to chemokines and thereby inhibit the activation of their cognate chemokine receptors, thus suppressing leukocyte recruitment and inflammation.
