Summary
In this project we will be studying the mechanisms of how an efficient anti cancer vaccine could be generated. We will be using cervical cancer associated human papillomavirus type 16 E7 protein as the model protein in an experimental vaccine model in mice. The results obtained from this project not only able us to design better vaccines against cervical cancers in women but against many other cancers and viruses.
The Role Of CD4+ T Cells In The Tumour Killing By CD8+ Memory T Cells.

Summary
It has been observed that human cancers grow in spite of the presence of tumour antigen specific memory CD8+ tumour killer T cells in the body. These memory killer cells are unable to kill the cancer. Our research work in a mouse model indicates that the CD8+ T cells can be activated to kill cancers if cancer antigen specific CD4+ T helper cells are activated. The mechanism how this happens is not clear. The role of regulatory or suppressor CD4+ T cells are also not known.

The mechanism how this happens is not clear. The role of regulatory or suppressor CD4+ T cells are also not known. In this proposal we wish to study the mechanism of how CD8+ memory T cells get activated to cancer killer cells by the CD4+ T helper cells. This information will help us to design better immunotherapies for cancer patients.Read moreRead less
Mechanisms Of Action Of The Antigen Presenting Cells That Impair Lymphoma-specific Cytotoxic T Lymphocytes

Summary
Our immune systems are continually fighting cancer. However, the cancer cells occasionally acquire mutations that enable them to subvert the immune system. Usually they do this by hiding under the appearance of normal tissue, but sometimes they activate the very mechanisms that are in place to shut-down immune responses when these are no longer necessary. The goal of this proposal is to identify such mechanisms and find ways of bypassing them, thus restoring anti-tumour activity in patients.
