Summary
Globally, tuberculosis is a leading cause of death with 9.6 million new diagnoses in 2014. The diagnosis of latent TB infection is important, but is difficult to make because current assays are suboptimal. We have developed a very simple assay which detects responses to TB antigens by co-expression of two surface markers expressed by CD4+ T cells. We propose to develop this into a highly standardised kit for the diagnosis of TB with our commercial partner Cytognos.

Summary
Papillomavirus (PV) is a sexually-transmitted virus that is a major cause of cervical cancer. Our study will determine how PV is able to form new virus particles inside infected cells. This is a critical part of the virus life-cycle, and a better understanding of this process may allow it to be trageted by anti-viral treatments. In addition, we will develop a method to create non-harmful virus particles which we will use to study human immune responses to the virus.

Summary
Aspergillus is a fungus found in soil, on farms and on construction sites. In those whose immune system is impaired it causes severe infection. The people who are particularly at high-risk of Aspergillus infection (called Invasive Aspergillosis) are those with acute leukaemia on chemotherapy or post bone marrow transplantation. Currently 15% of those at high-risk get Invasive Aspergillosis and 58-93% of those infected die. The main reason for this high death rate is that our current diagnostic t ....Aspergillus is a fungus found in soil, on farms and on construction sites. In those whose immune system is impaired it causes severe infection. The people who are particularly at high-risk of Aspergillus infection (called Invasive Aspergillosis) are those with acute leukaemia on chemotherapy or post bone marrow transplantation. Currently 15% of those at high-risk get Invasive Aspergillosis and 58-93% of those infected die. The main reason for this high death rate is that our current diagnostic tests are not good at detecting infection or often only detect the infection at advanced stages when treatment is ineffective. Because of the limitations of current diagnostic tests the current practice is to give empiric antifungal therapy (EAFT) early to treat Invasive Aspergillosis. However studies have demonstrated that this therapy has only resulted in a minor reduction in the mortality rates and it causes significant drug toxicity. It is a suboptimal treatment modality. New tests have been developed to diagnose Invasive Aspergillosis. These tests are for the detection of an Aspergillus protein in blood and for the detection of Aspergillus DNA in the blood. Available data suggests that these new tests are sensitive in the detection of Invasive Aspergillosis. Also other studies suggest that these new tests make an early diagnosis and seem to be able to monitor responses to treatment. However no study has been performed to date which demonstrates that the use of these tests can impact on important patient outcomes. This trial is designed to determine whether the use of the new tests to guide therapy will help improve treatment of Invasive Aspergillosis, reduce drug toxicity and reduce the death rate in the high-risk patients as compared with the current standard method of diagnosis and treatment with EAFT. If the trial is successful then this represents a significant advancement in the treatment and survival of leukaemic and bone marrow transplantation patients.Read moreRead less
