WELCOME TO THE ANTI-VIRAL T CELL IMMUNITY LABORATORY
Our group studies the biology and role of T cells during flavivirus infection and vaccination, with a particular interest in dengue virus infection.
Virus-specific T cells constitute an essential line of defence during viral infection and both an impaired or exacerbated T cell response are detrimental to the host. We are interested in understanding how T cells contribute to protective immunity and/or immunopathology during viral infection, particularly in the context of dengue infection. Understanding these mechanisms is critical for the development of effective vaccines and host-directed therapeutics.
Dengue virus causes the most prevalent mosquito-borne viral infection afflicting humans, with a recent estimate of 390 million infections per year. No specific therapeutics and only a partially protective vaccine are available for dengue. Dengue infection can cause an uncomplicated febrile illness or more severe syndromes which are characterized by increased vascular permeability and plasma leakage and can potentially progress to dengue shock syndrome. The host immune response is believed to drive severe disease, but the contribution of T cells in these processes remains unclear.
Mission and impact
We aim to define the T cell response during dengue infection and how it relates to clinical outcomes to inform the development of effective vaccines and host-directed therapies for dengue and related flaviviruses.
Our group performs translational immunological research on samples from patients, vaccine recipients and healthy donors. We address the phenotype, functional capacity and gene expression of T cells by utilizing a range of methodologies including multi-dimensional flow cytometry, CyTOF, ELISPOT, RNAseq and immunohistochemistry. Our work is performed in collaboration with Duke-NUS Medical School, Tan Tock Seng Hospital (Singapore), the Oxford University Clinical Research Unit (OUCRU), Ho Chi Minh City (Vietnam) and Cambridge University.
Currently our lab is working on:
- Phenotypic and transcriptional T cell signatures associated with severe dengue. Preliminary data suggests that T cell signatures associated with CD8+ T cell exhaustion and CD4+ T cell co-stimulation correlate with the development of severe dengue (McKinney et al Nature 2015). We aim to validate the association between T cell responses and immunopathology and define the mechanisms underlying these processes.
- Characteristics of circulating and tissue-resident T cells. We have previously shown that a large proportion of dengue-specific T cells reside within the skin tissue during acute dengue infection (Rivino et al Sc Transl Med 2015). We aim to define the nature and role of dengue-specific T cells in the skin and the relationship they have with their blood counterparts.
- Impact of cross-reactive T cell recognition on anti-viral T cell function. We aim to define the impact of cross-reactive T cell recognition of the different dengue serotypes or of related flaviviruses on the anti-viral function of CD8+ T cells to understand how this may affect disease outcomes during secondary dengue or sequential flavivirus infections.
- Yellow fever virus (YFV) vaccination as a model for flavivirus immunity. We aim to define how different components of the innate (NK cells) and adaptive (T and B cells) immune response are interconnected with each other and contribute to the efficacy of YFV, one of the most successful vaccines in history.
Our work has received the generous support of NMRC and Duke-NUS Medical School in Singapore.
