About Us

The Coussens lab focuses on the role of immune cells and their mediators as critical regulators of cancer development. During the early development of cancer, many physiological processes occur in the vicinity of 'young tumor cells' that are similar to processes that occur during embryonic development and to healing of wounds in adult tissue, e.g., leukocyte recruitment and activation (inflammation), angiogenesis (development of new blood supply) and tissue remodeling.

During tumor development however, instead of initiating a 'healing' response, activated leukocytes provide growth-promoting factors that typically help tumors grow. We are interested in understanding the molecular and cellular mechanisms that regulate leukocyte recruitment into neoplastic tissue, and the subsequent regulation those leukocytes exert on evolving cancer cells.
