About the Lab
The Laboratory for Vaccine and Immunotherapy Delivery (LVID), a.k.a. the Zaharoff Lab, in the Joint Department of Biomedical Engineering at NC State and UNC-Chapel Hill focuses on the development of innovative, translatable vaccine and immunotherapy delivery platforms that will have high clinical impact in an immediate timeframe. We primarily focus on cancer immunotherapies, but we also have efforts in illicit drug addiction and infectious diseases. Our multi-disciplinary research utilizes aspects of engineering, biomaterials, immunology, chemistry, physics, biology and nanotechnology.

No Santa, No Problem
We went to get our annual lab picture with Santa, as is our tradition, but the jolly old elf was taking a nap. So we had to improvise a little.

Goodbye Arkansas, hello North Carolina
The Z lab has moved to the Joint Department of Biomedical Engineering at the University of North Carolina-Chapel Hill and NC State University. We expect that this move will provide more opportunities to interface with oncologists and drive our cutting edge immunotherapies into the clinic. The goal is and always will be to eliminate the mortality and morbidity associated with cancer. Moving to North Carolina will help us achieve this goal. That said, we will miss our Arkansas colleagues and friends. Arkansas is a special place.

Sruthi's paper published in Marine Drugs
This paper settles a longstanding controversy over whether or not the ubiquitous biopolymer chitosan is immunogenic. Sruthi found that the wide varieties of chitosan from different vendors induce drastically different inflammatory responses. By painstakingly depyrogenating chitosan (i.e. removing endotoxins), Sruthi showed that pure chitosan is more or less immunologically inert.

Zaharoff Lab awarded funding for Breast Cancer work
A one-year grant from the Arkansas Breast Cancer Research Program was award to the Zaharoff lab to determine if immune suppression induced by breast cancer can be reversed with cytokine adjuvant therapy following standard-of-care tumor resection. The long term goal of the study is to re-establish immune function in the breast cancer patient in order to prevent progressive recurrences and metastasis which is responsible for more than 90% of breast cancer deaths.
