The chemokine receptor CXCR2 is vital for inflammation, wound healing, angiogenesis, cancer progression and metastasis. Adaptor protein 2 (AP2), a clathrin binding heterotetrameric protein comprised of α, β2, μ2 and σ2 subunits, facilitates clathrin‐mediated endocytosis. Mutation of the LLKIL motif in the CXCR2 carboxyl‐terminal domain (CTD) results in loss of AP2 binding to the receptor and loss...
The chemotaxis of phosphoinositide kinase-3 (PI3K)-inhibited differentiated HL-60 cells stably expressing CXCR2 was studied in a microfluidic switching gradient device that can generate stable and well-defined forward and reverse gradients. Wortmannin, a widely used PI3K inhibitor, was added during cell preparation and the experiment process. The studies quantify the chemotaxis gradient and the effects...
Human cytomegaloviruses (HCMVs) are important pathogens in immunocompromised patients and newborns. The viral chemokine, vCXCL-1, of the Toledo (Tol) strain of HCMV has been implicated in HCMV virulence. Chimpanzee CMV (CCMV) has several genes with similarity to the vCXCL-1 Tol gene, UL146. In order to test whether the CCMV viral chemokine, vCXCL-1 CCMV , is similar to vCXCL-1 ...
