The Harrison Lab is interested in understanding the functional significance of chemokine networks in the central nervous system with a primary focus on determining roles for these molecules in malignant brain cancers such as glioblastoma. Dr. Harrison studies mechanisms involved in tumor-immune cell interactions as well as direct effects of chemokines on glioma initiating cells. Experimental approaches encompass in vitro and in vivo methods and include the use of chemokine receptor selective pharmacological agents.
