Research Interests

Helen Heslop's research interest is adoptive immunotherapy with antigen specific cytotoxic T lymphocytes to augment antiviral and antitumor immunity. The research projects in this program test immunotherapy strategies for preventing and treating viral infections and malignancy. A key step in this strategy has been the translation of laboratory findings to Phase I and II clinical trials, as exemplified by studies of Epstein Barr virus-induced lymphoproliferative disease (EBV-LPD), a fatal complication in about 15% of recipients of unrelated or mismatched family member bone marrow transplants in the early 1990s. In collaboration with Dr Cliona Rooney, she developed methods for early diagnosis of this disease and procedures for generating cytotoxic T lymphocytes (CTLs) from bone marrow donors. Ultimately, she and her group undertook clinical trials showing that adoptively transferred CTLs were successful in preventing or eradicating EBV-LPD following bone marrow transplantation.

The success of these studies led to trials of EBV- specific CTLs in other EBV -associated malignancies (Hodgkin's disease and nasopharyngeal cancer) in which the tumor cells are less immunogenic than the ones treated previously. They are also currently evaluating if persistence and expansion of CTLs can be improved by pre-treatment of patients with lymphodepleting antibodies or vaccination with Class I or II peptides. They are also using similar approaches to generate antiviral CTLs specific for CMV and adenovirus for administration to patients post transplant. Other areas of research focus include identification of novel tumor antigens and genetic modification of CTLs to overcome tumor evasion strategies. In collaboration with Dr Brenner's group they are also evaluating if transduction of CTLs with chimeric antigen receptors can allow targeting of CD19+ve, CD30+ve and her2neu+ve malignancies. Dr Heslop holds a Doris Duke Distinguished Clinical Scientist Award.
