JAK3 pathway highlighted as leukemia target

An intriguing study published in Expert Review of Anticancer Therapy has revealed that the signaling protein JAK3 represents a viable target in the treatment of a broad range of B-lineage cancers, including acute lymphoblastic leukemia (ALL).

Dendritic cell vaccine induces immune responses in patients

A new process for creating a personalized vaccine may become a crucial tool in helping patients with colorectal cancer develop an immune response against their own tumors. This dendritic cell (DC) vaccine, developed at Dartmouth and described in a research paper published this week in the journal Clinical Cancer Research, was used after surgical resection of metastatic tumors to try to prevent the growth of additional metastases.

How HIV kills CD4 T cells

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be "bystander" cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.

Cannabis compounds trigger immune cells that promote cancer growth

An international team of immunologists studying the effects of cannabis have discovered how smoking marijuana can trigger a suppression of the body's immune functions. The research, published in the European Journal of Immunology, reveals why cannabis users are more susceptible to certain types of cancers and infections.

Harvard researcher to receive 2010 Naomi Berrie Award from Columbia University Medical Center

Columbia University Medical Center will present the 2010 Naomi Berrie Award to a Harvard researcher who has made important advances in understanding the molecular basis for links between obesity, diabetes and heart disease. A promising young investigator at Columbia will also be recognized for her novel investigations regarding the basis for disordered lipid metabolism in diabetes.

Study sheds light on poorly understood aspect of interaction of HIV with natural killer cells

Natural killer cells are major weapons in the body's immune system. They keep the body healthy by knocking off tumors and cells infected with viruses, bombarding them with tiny lethal pellets. But natural killer cells are powerless against HIV, a fact that has bedeviled science for over 20 years.

Study refocuses on rare group of neutralizing antibodies against HIV

Although people infected with HIV produce many antibodies against the protein encapsulating the virus, most of these antibodies are strangely ineffective at fighting the disease. A new study suggests why some of the most common of these antibodies don't work: they target the protein in a form it takes after the virus has already invaded the cell, when it's too late, report researchers at Children's Hospital Boston and their colleagues.

Abnormal levels of circulating auto-antibodies found in blood of COPD patients

Moderate to severe chronic obstructive pulmonary disease (COPD) may be an auto-immunity problem, according to researchers in Spain, who studied the presence of auto-antibodies in patients with COPD and compared them to levels of control subjects. They found that a significant number of patients with COPD had significant levels of auto-antibodies circulating in their blood, about 5 to 10 times the level in controls.

Research suggests new therapeutic approach to prevent transplant rejection

UCLA researchers have pinpointed the culprit behind chronic rejection of heart, lung and kidney transplants. Published in the Nov. 23 edition of Science Signaling, their findings suggest new therapeutic approaches for preventing transplant rejection and sabotaging cancer growth.

Medicare committee recommends expensive drug for some prostate-cancer patients

A new treatment for prostate cancer called Provenge won a vote of confidence from a Medicare coverage advisory committee Wednesday, suggesting the federal program is likely to pay for the $93,000-per-patient medicine.

Spleen cells may do more harm than good at site of spinal cord injury

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

Inovio achieves positive results in Phase I PENNVAX-B study for HIV

Inovio Pharmaceuticals, Inc. , a leader in the development of therapeutic and preventive vaccines against cancers and infectious diseases, announced today that it has achieved high vaccine-induced response rates and strong magnitude of immune responses in its Phase I clinical study of PENNVAX-B, a DNA vaccine for the prevention of HIV infection.

Scientists determine ways to stop damage, promote neuronal growth in spinal cord injury

If researchers could determine how to send signals to cells responding to a spinal cord injury, they might be able to stop one type of cell from doing additional damage at the injury site and instead, coax it into helping nerve cells grow.

NIH awards $10 million to advance technology for painless influenza vaccine delivery patch

The National Institutes of Health (NIH) has awarded $10 million to the Georgia Institute of Technology, Emory University and PATH, a Seattle-based nonprofit organization, to advance a technology for the painless, self-administration of flu vaccine using patches containing tiny microneedles that dissolve into the skin.

Researchers develop new vaccine delivery system for rotavirus infection

Researchers have developed a promising new approach to vaccination for rotavirus, a common cause of severe diarrheal disease that is responsible for approximately 500,000 deaths among children in the developing world every year.

Research suggests targeting spleen may promote healing of spinal cord injury

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

Discovery on immune system paves way to new vaccine against pneumococcal disease

A new breakthrough in the fight against pneumonia, meningitis and septicaemia has been announced today by scientists in Leicester and Dublin. The discovery will lead to a dramatic shift in our understanding of how the body's immune system responds to infection caused by Streptococcus pneumoniae and pave the way for more effective vaccines.
