Funding Amount
$112,366.00
Summary
The project will develop new cell models of Parkinson's disease utilising the recently discovered technique of inducing pluripotent stem cells from adult skin cells and differentiating them into the type of neurons that are affected in Parkinson's disease. The novel method will allow further insights to be gained into the molecular pathways involved in the disease and facilitate a search for means to rescue these cells from neurodegenerative processes.
Growth factors are essential molecules for normal brain development. Variations in the amount of the different growth factors have been implicated in such diseases as AlzheimerÍs and ParkinsonÍs disease. This project will study the precursor of a growth factor known as brain derived neurotrophic factor (BDNF) and what specific roles the precursor might play in brain development.
Molecular Dissection Of Cytokine-mediated Regulation Of Human B-cell Differentiation.

Summary
Interleukin 21 is a molecule which activates B cells. Defects in this pathway cause immunodeficiency where individuals cannot make antibodies, while constant activation has been reported in mouse models of autoimmunity. Examining these pathways will shed light on the causes of human immune disease, and may reveal molecules that could be targeted for the treatment of immunodeficiency and autoimmunity. Amplification of normal immune responses could lead to the development of improved vaccines.
Lymphocyte Differentiation And Genetics Of Primary Immunodeficiency

Summary
Primary immunodeficiency diseases affect a large number of individuals. Due to abnormal immune responses, these people are at risk of frequent, severe infections, as well as complications of autoimmune disease and cancer. Treatment often involves regular immunoglobulin (antibody) replacement. Through a better understanding of the mechanisms underlying these immunodeficiency diseases, we hope to be able to determine genetic causes, and more cost-effective and targeted treatment options.
Transcriptional Control Of Peripheral T Cell Differentiation During Pathogen Infection And Autoimmunity

Summary
White blood cells, specifically helper and killer T cells, play an important role in fighting infection. They are tightly regulated and if not properly controlled can lead to aggressive autoimmune diseases such as diabetes and multiple sclerosis. My studies will elucidate the mechanisms behind the regulation of T cells at steady-state and during disease. Insights gained from this project will have implications for the design of new approaches to combat infectious and autoimmune diseases.
Development Of A Cultured Tissue Substitute To Repair The Ageing Retina

Funding Amount

Summary
The ultimate goal of my research is to develop an effective, affordable and accessible treatment for patients afflicted with age related macular degeneration (AMD). The novelty of my study is that I will use a protein extracted from silk as a form of scaffold on which to grow new retinal tissue, with the view to replacing the damaged tissue that eventually leads to permanent loss of sight in AMD patients.
Investigating The Role Of TGF-beta In Resident Memory T Cell Induction And Maintenance

Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
MIGRATORY CHARACTERISTICS OF SKIN-DERIVED NEURAL PRECURSORS AS A NOVEL REGENERATIVE THERAPY FOR ALZHEIMER’S DISEASE

Funding Amount

Summary
Memory decline in Alzheimer's disease is linked to a massive loss of neurons and the connections between these cells. Stem cell therapy has the potential to combat this neuronal loss by replenishing the brain with healthy functional neurons. This study aims to develop a new type of neural stem-like cell, termed skin-derived neural precursors, which can be isolated from a patient’s own skin. The outcomes from this work will provide the necessary data for progress into human clinical trial.
The Mechanisms Of SIV Entry Of Follicular Helper T Cells

Funding Amount
$95,313.00
Summary
Follicular helper T (Tfh) cells are a type of immune cells essential in antibody production. Preliminary data shows that SIV infects macaque Tfh cells. In this project, we will investigate the mechanisms by which SIV enters into Tfh cells, and test the susceptibility of human Tfh cells to HIV-1 infection ex vivo. This project will enable understanding of the fate of Tfh in HIV infection and its role in HIV host defense and it may facilitate the design of vaccine against HIV.
