The Serody laboratory is focused on the migration of dendritic cells and subpopulations of T lymphocytes during graft-versus-host disease (GVHD) after allogeneic stem cell transplantation and as a consequence of induction of an immune response to tumors using vaccine therapy. There are four predominant areas that we focus:
- Migration of T cells that lead to GVHD during stem cell transplantation:
Our laboratory has been a pioneer in investigating how white cells migrate to cause GVHD. Recently we have focused on the site of induction of GVHD, and how regulatory T cells that block GVHD function to do this. We have shown that chemokines mitigate migration during GVHD as a bimodal process involving host production initially followed by donor T cell production eventually leading to GVHD (ref 9). Currently we are focused on the identification of specific proteins that mediate migration into specific GVHD target organs which could be used to generate therapeutic treatments. For this we are using novel in vivo imaging (ref 1) approaches to track T cells from transgenic mice that we generated that express eGFP. Our group is actively trying to understand the phenotype of T cell that mediates acute and GVHD in animal models and clinically.
- Breaking of tolerance to self proteins using dendritic cells (DCs):
We are involved in research to determine the best means to activate DCs with tumor antigens to break tolerance both in animal models and in clinical trials. Our current work has involved characterizing the ability of alphavirus replicon particles to infect DCs and to use these to overcome tolerance (ref 11). We are also focused on the how B and T cell responses synergize in tumor vaccines and methods to deliver vaccines with chemotherapy.
- Blocking migration of regulatory T cells to enhance tumor vaccination:
Our group was the first to show a specific role for the chemokine receptor CCR5 in the function of Treg cells (ref 9) and the first to show that loss of these receptors improves tumor vaccine therapy. We have exploited this finding to investigate if blocking the migration of Treg cells can enhance the ability of tumor vaccines to break tolerance.
- Immune response during cancer and metastasis:
We are focusing on the role of immune cells in the growth of tumor locals locally and at distant sites. Additionally, we are looking at how immune cells modulate the tumor stroma to promote tumor growth.
