Interleukin-15 encourages CD8+ T cells to proliferate and reduces their tolerance to tumor antigens

Certain types of white blood cells assist the body in destroying cancerous tumors. Among these are CD8+ T cells. The T is for thymus, the gland near the base of the throat that both raises up and weeds out blood cells involved in immune responses.

Infant transplant patients resist infections that kill adult AIDS patients - possible new treatments for debilitating diseases

Investigators have discovered that some type of protective system goes into action in some cases when a baby's immune system is deficient.

Nanotechnology and biochemistry provide new way to study T cell signaling

Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, combining nanotechnology with biochemistry, have created unique synthetic membranes that, for the first time ever, enable them to directly control signaling activity in living T cells from the immune system. Already their experiments have yielded surprising results.

New discoveries help explore the function of regulatory T cells in autoimmune disease and in cancer

More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.

Study shows that high-fat diets correlate to a chronic inflammatory state in the liver,

Mice that were fed diets high in fat and sugar developed immune system abnormalities in their livers, including reduced numbers of natural killer T (NKT) cells. These diet-related changes may contribute to obesity-related liver disease, according to a new study.

Researchers discover way to dramatically boost the output of immune system cells from the thymus

Mayo Clinic researchers have discovered a way to dramatically boost the output of immune system cells from the thymus, which may lead to improved cancer vaccines, as well as to ways to otherwise strengthen immune responses.

Australian scientists rejuvenate the immune systems of mice and humans using a common hormone

The scientists, led by Associate Professor Richard Boyd and Dr Jayne Sutherland from the Monash Immunology and Stem Cell Laboratories, have revitalised the thymus which produces the T cells required to fight infection but which shuts down from early adulthood.

Researchers clarifiy role of Notch protein in T-cell development

Researchers at the University of Pennsylvania School of Medicine have recently clarified the role of the Notch protein in T-cell development. T cells are required for many aspects of immunity, including fighting viral infections, providing cancer surveillance, and regulating multiple aspects of the immune response.

Stem cells grown in lab mirror normal developmental steps

Johns Hopkins scientists have developed a way to study the earliest steps of human blood development using human embryonic stem cells grown in a lab dish instead of the embryos themselves.

New predictor for blood transplant success

The success of blood stem cell transplants used to treat diseases such as leukemia, Hodgkin’s lymphoma and aplastic anemia may soon become more predictable, thanks to a discovery made by researchers at the University of British Columbia.

Laboratory model of immune system overcomes ethical constraints on studies of hematopoietic stem cells in humans

Scientists at St. Jude Children’s Research Hospital have joined with colleagues at several other institutions to develop a laboratory model of the human immune system. This model will allow scientists to study ways for improving the results of hematopoietic stem cell (HSC) transplantation without putting patients at risk.

Two-photon imaging gives real-time video of cells in living tissue

Biologists have a new tool to track and videotape cells moving about inside living tissue.

Scientists have found genetic regions that, when defective, allow the immune system to attack the pancreas

Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas -- the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings, published yesterday, March 22, in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients.

Discovery that sheds new light upon the growth and development of human natural killer (NK) cells

Scientists here have made a major discovery that sheds new light upon the growth and development of human natural killer (NK) cells, powerful but somewhat mysterious components of the body’s immune system that are the first line of defense against cancer and infectious diseases.

Scientists gain new insight into DiGeorge syndrome

A collaboration of European scientists has uncovered new insight into the most common chromosomal microdeletion syndrome in humans.

Scientists identify immune-system mutation

A team of Fox Chase Cancer Center scientists led by immunologist Dietmar J. Kappes, Ph.D., has identified the genetic mutation that keeps a mouse strain from developing white blood cells, or lymphocytes, called helper T cells. The report by Kappes and his colleagues appears in the Feb. 24 issue of Nature.

Level of immune cell DNA in the blood might help predict success of stem cell transplantation

Measuring the quantity of a certain type of immune cell DNA in the blood could help physicians predict whether a bone marrow stem cell transplant will successfully restore a population of infection-fighting cells called T lymphocytes in a child.

A gallery of highly-specific, gene and protein “mug shots” of cancer types would be a powerful for oncologists

Doctors would like to diagnose malignancies rapidly by matching them with highly-specific genetic “mug shots” based on the presence of characteristic mRNAs or proteins. This kind of specificity would facilitate screening and early detection, and would potentially allow targeted treatments specific to each type of cancer

Viral Genetics announces effects of VGV-1 in antiretroviral non-responding HIV infections

Viral Genetics announced today that the results of a clinical trial of its investigational therapy for HIV infection, VGV-1, were recently published in a peer reviewed journal, HIV & AIDS Review.

An immune system in a bottle would allow faster and easier production of a flu vaccine

University of Michigan associate professor Nicholas Kotov believes that one day, the cells in those honeycombs can be used to grow spare parts for our bodies, or even an entire artificial immune system in a bottle.
