Targeted Therapies of CLL and B-Cell Malignancies: Biological, Small Molecule Immunopharmacuetical, Delivery, and MicroRNA

Targeted cancer therapies are drugs or other substances that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. The Byrd lab has a long history of innovation and investigating targeted cancer therapies that leverage the immune response. CD19 and IL-21 are examples of novel engineered biological therapies that are developed to enhance antibody therapeutics through direct and immune mediated mechanisms. CD-37-SMIP is a small molecule immune-phamacuetical that promotes antibody-dependent cellular cytotoxicity using a B-cell lineage specific antigen that was previously neglected. Combining research of targeted biological and immunopharmacueticals is leading the way to develop targeted drug delivery using immunonanoparticles. The discovery that the immunosuppressant FTY720 targets phosphatases in leukemia and lymphoma has introduced a new therapeutic target. New collaborations with colleagues at The Ohio State University are investigating the clinical application of microRNAs for therapy.
