Harvard scientists partner to develop and distribute new tuberculosis vaccine
02-17-2007 · EurekAlert!Bioengineers and public health researchers at Harvard University have developed a novel spraying method for delivering the most common tuberculosis (TB) vaccine, providing a new low-cost and scaleable technique that offers needle-free delivery and greater stability at room temperature than existing methods. The process could one day provide a better approach for vaccination against TB and help prevent the related spread of HIV/AIDS in the developing world.

- Mice help researchers understand chlamydia
10-29-2007 · EurekAlert!
Genetically engineered mice may hold the key to helping scientists from Queensland University of Technology and Harvard hasten the development of a vaccine to protect adolescent girls against the most common sexually transmitted disease, chlamydia. Dr Michael Starnbach from Harvard Medical School is in Australia to work with QUT on a joint research project using a "mouse model" to study how the immune system responds to infections such as chlamydia.

- Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine
04-15-2007 · EurekAlert!
Experimental vaccines to help the immune system fight tumors have rarely been designed to directly stimulate helper T cells, one of the body's most critical immune responders, because of the difficult process required to isolate and clone antigens for vaccine development. Now, a new technique may allow scientists to create a melanoma vaccine able to stimulate helper T cells. The approach may also aid in the development of other vaccines against cancers or infectious diseases.

- Handicapping tuberculosis may be the way to a better vaccine
08-01-2007 · EurekAlert!
Howard Hughes Medical Institute investigator William R. Jacobs and colleagues have produced a genetically altered strain of tuberculosis, that elicits a stronger immune response than the current vaccine, bacillus Calmette-Guйrin. The new vaccine improves survival of infected animals and may help put scientists on track to replace BCG, which has been used for nearly a century although it is largely ineffective.

- In a first, scientists develop tiny implantable biocomputers
05-21-2007 · EurekAlert!
Researchers at Harvard University and Princeton University have made a crucial step towards building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these "molecular doctors," constructed entirely of DNA, RNA, and proteins, could eventually revolutionize medicine by directing therapies only to diseased cells or tissues.

- Scientists discover novel way to remove iron from ferritin
11-02-2007 · EurekAlert!
A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, PhD, is the first to suggest that a small protein or heptapeptide could be used to accelerate the removal of iron from ferritin. The results of this study may help scientists develop new medications that dramatically improve the removal of excess iron in patients diagnosed with blood diseases such as B-Thalassemia (Cooley's anemia) or sickle cell disease.

- Novel vaccine concept developed by scientists at the Wistar Institute
01-31-2008 · EurekAlert!
A new vaccine design strategy developed by scientists at the Wistar Institute could help to develop vaccines against diseases like AIDS and cervical cancer. The secret is using a herpes simplex protein called glycoprotein D to block a receptor molecule on antigen-presenting cells. Wistar scientists showed that vaccine vectors made by fusing glycoprotein D with genes from HIV and HPV antigens increase the immune system's response to those antigens in cell cultures and mice.
