Identifying epigenetic mechanisms that drive decline in immune function and the ability to respond to vaccines, infections and cancers in the elderly.
This project seeks to pinpoint cellular and molecular epigenetic mechanisms that drive age-related immune-senescence and inflammation, critical to the decline in immune function and ability to respond to vaccines, infections and cancers in the elderly.
The value of the Scholarship is equivalent to an RMIT full Scholarship.
This Scholarship will be available for 3.5 Years.
Applications are open now.
Position will remain open until filled.
Applicants need to have a background in immunology, genetics or bioinformatics. They must have completed a relevant Bachelor’s Degree and Honour’s or Master’s.
Previously, we and others have observed reduced vaccine efficacy in the elderly as well as increased susceptibility to infections and cancers . Age-related immune dysfunction, chronic inflammation, and inadequate nutritional status may reduce our capacity to resolve infections and cancers, as well as to promote sufficient vaccine response.
This project has been designed to pinpoint cellular and molecular epigenetic mechanisms that drive age-related immune-senescence and inflammation, critical to the decline in immune function and ability to respond to vaccines, infections and cancers in the elderly. Additionally, nutritional status measured by the dietary inflammation indexes and/or plasma nutritional biomarkers will be measured to understand the influence of nutrition on the immune response. Here, we will use various cohorts from human trials, to unravel the role of immune dysfunction, inflammation, and nutritional status on modulation of infections-, cancers- and vaccine-generated immune responses in older individuals, and the epigenetic mechanisms that underlie such modulation.
Underpinning the molecular epigenetic changes that drive the age-related immune dysfunction and inflammation, or are formed by the inadequate nutritional status will point towards molecular mechanisms that may be involved in suboptimal responses to vaccination in the elderly, as well as provide leads for novel therapeutic strategies.
