Literature Highlights
When a chemokine binds to its G protein-coupled receptor one of the consequences of receptor activation is a decrease in the levels of receptor present on the cell surface due to more rapid internalization. The mechanism of GPCR internalization

CXCL12 and its receptor CXCR4 have well known roles in bone marrow homing and
mobilization of hematopoietic stem cells and neutrophils, but inflammatory neutrophil
recruitment is governed by CXCR2 and its

Literature Highlights
Plasma concentrations of inflammatory proteins can serve as biomarkers for cardiovascular disease (CVD). Previous studies had linked the T cell chemokine CXCL10/IP-10 to hypertension and heart failure, but failed to achieve the statistical significance necessary for its use as a biomarker for human disease.
