A dendritic cell subset targeting approach for defining immune function and tailoring immunotherapy

点击翻译按钮获取中文摘要

Dendritic cells are important sentinel cells of the immune system that orchestrate our immune responses against invading pathogens. There are different types of dendritic cells and they perform different jobs. We have a series of antibodies that can recognise markers on the surface of different dendritic cells populations. We can use these antibodies as homing devices to deliver foreign material to individual dendritic cell subpopulations and thereby manipulate the type of immune response generated. Effectively, we aim to tailor immune responses to fight a particular bacteria, virus, parasite, or even cancer cells. The current proposal will extend the number of antibodies we test for their ability to generate tailored immunity. We will examine a number of new molecules for their ability to shuttle foreign material to dendritic cells and their ability to stimulate immune responses. Next, we will test these homing devices as vaccines and their ability to prevent or treat cancer. Our aim is to develop a robust, highly efficient, generic, vaccination approach for cancer immunotherapy.
