Title — Signal Processing meets Immunology- Towards a Hepatitis C Vaccine via High-Dimensional Covariance Estimation
Abstract — Chronic Hepatitis C Virus (HCV) infection is one of the leading causes of liver failure and liver cancer, affecting around 3% of the world’s population. Current treatment for HCV is expensive, frequently fails, and accompanies massive side effects. Thus, there is an urgent need for an efficient HCV vaccine. The major problem related to the design of a HCV vaccine is its extreme variability that helps it to evade immune surveillance. This talk will discuss a new approach to vaccine design for HCV based on finding “multi-dimensionally conserved residues?. Effectively, the approach is based on a statistical study of the diverse publicly-available HCV sequences, using methods common in statistical signal processing; primarily, robust covariance estimation. Our analysis reveals parts of the virus that may be most susceptible to immune pressure, despite the high mutability of the virus. These studies are backed up with clinical evidence and serve as a basis for new vaccine designs that we propose. The talk is directed towards an electrical engineering or statistical signal processing audience, and assumes no prior knowledge of biology or immunology.
