Tasmanian devil cancer genome mapped

Researchers, including those from Wellcome Trust Sanger Institute near Cambridge, have sequenced the genome of a facial cancer that is threatening the existence of the Tasmanian devil.

New triple-therapies found cost-effective for chronic hepatitis C patients with advanced liver disease

A towering $60,000 bill, a year of fierce, flu-like symptoms and a running risk of depression are among the possible costs of two new hepatitis C treatments. But according to Stanford University health policy researchers, they might be worth it.

The final link in world's longest living-donor kidney transplant chain

A Loyola University Medical Center patient has become the final link in the world's longest living-donor kidney transplant chain.

Targeting patient's own dendritic cells may help restore the immune system

Aggressive ovarian tumors begin as malignant cells kept in check by the immune system until, suddenly and unpredictably, they explode into metastatic cancer. New findings from scientists at The Wistar Institute demonstrate that ovarian tumors don't necessarily break "free" of the immune system, rather dendritic cells of the immune system seem to actively support the tumor's escape.

DNA ‘nanorobot’ effectively targets cancer leaving healthy cells untouched: Study

Researchers have developed ‘nano-sized’ probes built from DNA that can seek and destroy cancer cells, leaving healthy cells untouched. These ‘nanorobots’ release their drug payload only when they reach and identify their target and are believed to improve many treatments for disease.

Study identifies USP15 as a critical protein in cancer

After years studying the molecular bases of glioblastoma - the most common brain tumor and one of the most aggressive of all cancers, the group led by Dr. Joan Seoane , Director of Translational Research at the Vall d'Hebron Institute of Oncology (VHIO) and ICREA Research Professor has today published a study in Nature Medicine identifying USP15 as a critical protein in cancer which, thanks to its molecular characteristics, shows enormous therapeutic promise.

Study reveals potential strength of different anti-HIV combination drugs

Using a mathematical formula that carefully measures the degree to which HIV infection of immune system cells is stalled by antiretroviral therapy, AIDS experts at Johns Hopkins have calculated precisely how well dozens of such anti-HIV drugs work, alone or in any of 857 likely combinations, in suppressing the virus. Results of the team's latest research reveal how some combinations work better than others at impeding viral replication, and keeping the disease in check.

Vaccines are for people of all ages, not just children and seniors

Keeping up with vaccines is not always easy, particularly if you live in a household with family members of different ages. Vaccination needs can also change quickly if there's an outburst of a disease.

Scientists discover the off signal for inflammation

Proteins, the building block for all living organisms, are the ultimate transformers - able to splice and switch roles and functions within the human body. But when these changes go wrong, diseases such as cancers and arthritis may result, says University of British Columbia researcher Chris Overall.

Scientists discover molecular mechanism behind MS relapses

Scientists have discovered a molecular mechanism that could help explain how multiple sclerosis (MS) and other autoimmune diseases can be exacerbated by the onset of an infection.

Study reveals immune mechanism for surveillance over EBV infection

Some 90 percent of people are exposed to the Epstein Barr virus (EBV) at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells.

Evolutionary biologist receives LRI grant for lupus research

Evolutionary biologist Harmit Singh Malik, Ph.D., of Fred Hutchinson Cancer Research Center, has received a $300,000 grant from the Lupus Research Institute to study the potential role of "genetic conflicts" in the development of lupus, an autoimmune disease.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.

Study reveals new guiding principles for cancer genomics

That our chromosomes can break and reshuffle pieces of themselves is nothing new; scientists have recognized this for decades, especially in cancer cells. The rules for where chromosomes are likely to break and how the broken pieces come together are only just now starting to come into view.

University of Georgia researcher to develop first Chagas vaccine for pets

Chagas disease is the single most common cause of congestive heart failure and sudden death in the world. The devastating parasitic infection affects millions of people throughout Central and South America. But as global travel increases, it's becoming a greater threat in the United States and Europe as well.

Four new drugs can extend survival and prognosis of prostate cancer

After a decade and a half of near stagnation, four new drugs could help make advanced prostate cancer a chronic illness instead of a terminal disease, a leading Colorado prostate cancer expert says.

Researchers sequence genome of Tasmanian devil contagious cancer

Researchers have sequenced the genome of a contagious cancer that is threatening the Tasmanian devil, the world's largest carnivorous marsupial, with extinction. Cataloguing the mutations present in the cancer has led to clues about where the cancer came from and how it became contagious.

IKK2 enzyme plays a key role in proliferation of lung cancer cells

Drugs targeting an enzyme involved in inflammation might offer a new avenue for treating certain lung cancers, according to a new study by scientists at the Salk Institute for Biological Studies.

First accurate predictive model to differentiate between dengue fever and dengue hemorrhagic fever

Researchers at the University of Texas Medical Branch have developed the first accurate predictive model to differentiate between dengue fever (DF) and its more severe form, dengue hemorrhagic fever (DHF).

New way to improve vaccines against cancer and infectious diseases

Research groups from Charité Universitätsmedizin Berlin and the University of Geneva have discovered a new way of improving vaccines against infectious diseases and for use in cancer therapies. Scientists have shown a basic new mechanism that stimulates the body's own alarm signals in case of viral infection to animate the immune system to maximum performance.
