Session Abstract – PMWC 2022 Silicon Valley


The analysis of blood for circulating tumor cells (CTC), circulating tumor DNA (ctDNA), extracellular vesicles, or more recently, tumor-educated platelets has opened new avenues for cancer diagnostics, including early detection of tumors, improved risk assessment and staging, as well as early detection of relapse to improve patient care. The track will introduce the up-to-date technologies used in liquid biopsy and review the clinical utilities in cancer screening, detection of minimal residual diseases, selection of molecular-targeted drugs, as well as monitoring of treatment responsiveness.

Dr. Azzi is a physician scientist who is leading a NIH funded laboratory that focuses on understanding the immune-regulatory arm of the immune system in transplantation, autoimmunity and cancer with the goal of developing more targeted and safer therapeutic strategies. Currently, a major focus of his research is CD4 and CD8 regulatory T cells and their activation induced cell death in addition to engineering cell therapies. Dr. Azzi’s laboratory is also exploring multiple genomics and proteomics approaches to develop biomarkers that noninvasively detect rejection in kidney transplant recipients and measure the immune function of immunosuppressed patients.


Talk
Beyond Concept to Clinical Application in Kidney Diseases
The traditional biomarkers currently used to monitor a kidney allograft for rejection or autoimmune mediated kidney diseases are late markers of injury and they lack sensitivity and specificity. Biopsies on the other hand, are invasive and costly. Urinary exosomes, tiny vesicles released into the urine that carry parent cells’ proteins and nucleic acids, reflect the biologic function of the parent cells within the kidney, including immune cells. Their stability in urine makes them a potentially powerful tool for liquid biopsy and a noninvasive diagnostic biomarker for kidney-transplant rejection. This talk will describe the current efforts to develop urinary exosomes-based biomarkers to detect allograft kidney rejection and other kidney related diseases.
