Biography
Dr. Crawley received a B.Sc. in Microbiology and Immunology from McGill University in Montreal, Quebec (Canada) in 1999. In 2004 she completed a Ph.D. in Immunology with Dr. Bruce N. Wilkie in the Dept. of Pathobiology at the University of Guelph’s Ontario Veterinary College (Guelph, Ontario, Canada). Dr. Crawley then trained as a postdoctoral fellow in Dr. Jonathan B. Angel’s laboratory at the Ottawa Hospital Research Institute, and published 10 peer-reviewed scientific research and review articles on the immunopathogenesis of HIV infection. Dr. Crawley was funded by an Ontario HIV Treatment Network (OHTN) Fellowship award and awarded a University of Ottawa Faculty of Medicine Postdoctoral Award of Excellence (2007).

Generalized Liver- and Blood-Derived CD8+ T-Cell Impairment in Response to Cytokines in Chronic Hepatitis C Virus Infection
PLoS ONE2016
Generalized CD8+ T-cell impairment in chronic hepatitis C virus (HCV) infection and the contribution of liver-infiltrating CD8+ T-cells to the immunopathogenesis of this infection remain poorly understood. It is hypothesized that this impairment is partially due to reduced CD8+ T-cell activity in response to cytokines such as IL-7, particularly within the liver. To investigate this, the phenotype and cytokine responsiveness of blood- and liver-derived CD8+ T-cells from healthy controls and individuals with HCV infection were compared.
Influence of female sex on hepatitis C virus infection progression and treatment outcomes
European Journal of Gastroenterology & Hepatology2016
The influence of sex on hepatitis C virus (HCV)-related outcomes is often neglected. The effects of sex on liver fibrosis progression and the effect of socioeconomic status on management are unclear.
Complexed soluble IL-7 receptor α and IL-7 increase IL-7-mediated proliferation and viability of CD8⁺ T-cells in vitro
Cellular Immunology2015
Many soluble cytokine receptors inhibit cytokine bioactivity, while others prolong ligand activity. The biological role of an endogenous soluble form of IL-7Rα, or its therapeutic effects on CD8+ T-cells are unknown. We demonstrate that recombinant IL-7Rα-Fc, when pre-incubated with IL-7, enhances IL-7-induced CD8+ T-cell proliferation and viability of human or murine CD8+ T-cells.
Jak/STAT and PI3K signaling pathways have both common and distinct roles in IL-7-mediated activities in human CD8+ T cells
Journal of Leukocyte Biology2014
IL-7 plays an important role in T cell survival, function, and memory cell development, yet the role of cytokine signaling pathways in these processes has not been fully elucidated. Moreover, the underlying mechanisms for the observed impairment of IL-7 activity in diseases, such as HIV infection, breast cancer, and autoimmunity, are not well understood.
The influence of HIV on CD127 expression and its potential implications for IL-7 therapy
Seminars in Immunology2012
Interleukin-7 (IL-7) is critical for early T-cell development and plays an important role in T-cell homeostasis, differentiation and function. Signalling via the IL-7 receptor is dependent on the expression of its components, IL-7Rα (CD127) and IL-2Rγ (CD132) and is mediated in part by alterations in CD127 expression levels in different cell subsets.
