Week 3-Study Could Lead To Novel Therapy For Cancer/HIV

In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer. The technique involves delivering DNA into the immune system's instructor cells. The DNA directs these cells to overproduce a specific protein that jumpstarts important killer T cells. These killer cells are typically repressed in patients who have HIV or cancer, said José A. Guevara-Patino, MD, PhD, senior author of the study. Guevara is an Associate Professor in the Oncology Institute of Loyola University Chicago Stritch School of Medicine. Guevara and colleagues reported their technique proved effective in jumpstarting defective immune systems in immuno-compromised mice and in human killer T cells taken from people with HIV. Guevara said a clinical trial in cancer patients could begin in about three years.

Week 2- Vaccines for HIV and other diseases

Scientists from Trinity College Dublin have discovered a new 'off switch' in our immune response which could be boosted in diseases caused by over-activation of our immune system, or blocked to improve vaccines. The findings are published this week in the journal Nature Communications. The research was funded by Health Research Board, Ireland and Science Foundation Ireland. The research team, led by Dr Anne McGettrick and Professor Luke O'Neill, at the Trinity Biomedical Sciences Institute, have discovered that a protein, called TMED7, can shut down part of our immune system once an infection has been eliminated. "Without stop signals like TMED7 our immune system would continue to rage out of control long after the infection has been cleared, leading to diseases such as septic shock," says Dr Anne McGettrick. Manipulating these stop signals could help dampen down our immune system to prevent it attacking our own bodies. In certain cases, removing stop signals and boosting our immune system can be advantageous. Several diseases such as Malaria and HIV are lacking good vaccines and research laboratories and drug companies around the world are looking to solve this problem.

Week 1- Budget Cuts for Diseases in America

The prospect of deep cuts in the federal budget threatens to reverse the dramatic progress of a bipartisan US commitment to defeat neglected diseases in developing countries, according to a new report releases by the Global Health Technologies Coalition (GHTC). Federal investments in global health research and development (R&D) programs that span multiple agencies have helped nurture an array of new vaccines, medicines, diagnostics, and other health products needed to combat diseases like HIV/AIDS, malaria, tuberculosis (TB), and childhood killers like pneumonia and diarrheal diseases. Despite these advances, President Obama's budget request for 2013 calls for several decreases for global health when compared with last year's levels. Several global health R&D programs at US agencies also saw drastic funding cuts.
