Randall Johnson Project

Role of hypoxic response in immunotherapy 

We have investigated how T cells utilise hypoxic response to allow immune response.  We are actively investigating this in terms of models of immunological response to cancer; and we are also asking how myeloid/lymphoid interactions are affected by the response to oxygenation. The project will employ specific hypoxia-induced molecules, particularly metabolites related to hypoxic response, and determine how they can be employed to improve immunotherapeutic responses such as epigenetic changes leading to immune cell persistence in vivo.
