Dendritic cells as a new player in arteries and heart valves

In 1973, Ralph M. Steinman launched a new scientific discipline when he published his discovery of the dendritic cell, an odd-shaped player in the immune system.

First immune danger receptor' found

Cancer Research UK scientists have found the first biological receptor that alerts the immune system to 'dangerous' or abnormal cell death, according to research published in Nature.

Oncostatin M may be a promising drug for treating viral hepatitis and liver cancer

This research, coordinated by the doctors Jesús Prieto, Esther Larrea, Pablo Sarobe, Iranzu González and Rafael Aldabe, has been published in the Journal of Virology ; a journal of the American Society of Microbiology.

Ritalin may change brain in same way cocaine does

A common treatment for attention deficit/hyperactivity disorder, prescribed millions of times a year, may change the brain in the same ways that cocaine does, a new study in mice suggests.

Molecule that suppresses immune response under study in type 1 diabetes

The idea is to teach the immune system of children at high risk for type 1 diabetes not to attack the insulin-producing cells of the pancreas.

Stat3 signaling tips the balance of immunity in favor of cancer

New research reveals how a cancer-associated protein enables tumor cells to evade the immune system by both suppressing antitumor influences and promoting tumor-enhancing conditions, in essence turning the immune system to the dark side of the force.

New insights into growth factor's role in brain development

New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined.

Helicobacter pylori can multiply in autophagic vesicles

Helicobacter pylori , a Gram-negative, flagellated, microaerophilic bacterium, can selectively colonize in the human stomach.

Component of DNA stimulates and suppresses the immune response

A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say.

Implants mimic infection to rally immune system against tumors

Bioengineers at Harvard University have shown that small plastic disks impregnated with tumor-specific antigens and implanted under the skin can reprogram the mammalian immune system to attack tumors.

Biodegradable nanoprobe images new blood vessel growth

Angiogenesis, the growth of new blood vessels, plays a critical role in several chronic human diseases, including metastatic cancer. In fact, several new anticancer therapies are designed to starve tumors by shutting down angiogenesis, but the lack of a good assay for quantifying angiogenesis in the body has hampered the development of effective antiangiogenesis therapies.

Gene therapy kills brain tumors through selective recruitment of immune cells

Scientists seeking to harness the power of the immune system to eradicate brain tumors face two major hurdles: recruiting key immune cells called dendritic cells into areas of the brain where they are not naturally found and helping them recognize tumor cells as targets for attack.

Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.

A new mechanism regulates type I interferon production in white blood cells

A study from a team of researchers led by Dr. Andrew P. Makrigiannis, Director of the Molecular Immunology Research Unit at the IRCM, has identified a new mechanism regulating interferon production.

Active Hexose Correlated Compound shown to enhances immune system by increasing production of key dendritic cells

A recently published study in Nutrition and Cancer (60(5), 643-651) by researchers at Kansai Medical University in Osaka, Japan has shown that AHCC (Active Hexose Correlated Compound) enhances immune function by increasing the number of dendritic cells (DCs).

Mucosal lining of the female genital tract no barrier to HIV sexual transmission

Contrary to a widely-held assumption about heterosexual transmission of HIV, the normal mucosal lining of the female genital tract is not a foolproof barrier to viral penetration, scientists at the Northwestern University School of Medicine in Chicago report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.
