These new data are an essential step towards understanding the operation of these key cells in the immune system, and they could provide a new therapeutic approach to fighting infection. They also suggest that the operation of NK cells must be precisely regulated to guarantee an optimum immune reaction. Details of this work are published in the 20 January 2012 issue of the journal Science. Our bodies are subject to attack by many different infectious particles (bacteria, viruses, etc.),...

The immune system is capable of recognizing tumor growth, and naturally mounts an anti-cancer defense. Dendritic cells (DCs) can take up tumor-derived molecules (antigens) and present them to T cells, and those "primed" T cells are then able to recognize and kill tumor cells. In recent years, researchers have attempted to capitalize upon these natural immune responses to develop new therapies- namely, by generating a pool of tumor antigen-pulsed DCs that might be used as vaccines to augment...

Our immune systems contain three fundamentally different types of cell:  B-cells, T-cells and the mysteriously named Natural Killer cells (NK cells), which are known to be involved in killing tumor cells and other infected cells.  Experiments to investigate the function of NK cells have proven difficult to interpret because the interactions between the various components of the immune system make it almost impossible to isolate effects of individual cell types.  This has...

The findings challenge long-held dogma in field of immunology A team of scientists from The Scripps Research Institute have uncovered a previously unknown regulatory mechanism in the body's response to eliminate pathogens, such as bacteria and viruses. The findings challenge a long-held dogma in the field of immunology and have potential implications for far-ranging topics from how vaccines should be administered to the origin of autoimmunity. The results of the study, led by Scripps Research...

Novel imaging system paints a clear picture of T-cell actions in animal models, providing key insights into immune responses "These immune responses are a key consideration in developing strategies to improve transplant outcomes," explains co-senior author Terry Strom, MD, Co-director of the Transplant Institute at Beth Israel Deaconess Medical Center (BIDMC) and Professor of Medicine at Harvard Medical School (HMS). "The fate of a transplant following withdrawl of immunosuppressive therapy...

SEATTLE and WASHINGTON, April 21 /PRNewswire-FirstCall/ -- Dendreon Corporation (Nasdaq: DNDN) announced the presentation of additional data from the Phase 3 IMPACT (IMmunotherapy for Prostate AdenoCarcinoma Treatment) clinical trial showing evidence of immune responses in patients treated with PROVENGE® (sipuleucel-T) and supporting its proposed mechanism of action. The data were presented at the American Association for Cancer Research (AACR) 101st Annual Meeting 2010...

Yale University engineers have found that the defects in carbon nanotubes cause T cell antigens to cluster in the blood and stimulate the body's natural immune response. Their findings, which appear as the cover article of the April 20 issue of the journal Langmuir, could improve current adoptive immunotherapy, a treatment used to boost the body's ability to fight cancer. Adoptive immunotherapy involves extracting a patient's blood so that the number of naturally occurring T cells (a type of...

COLUMBIA, Md., Jan. 12 /PRNewswire/ -- Cylex Incorporated® announced today that the American Medical Association (AMA) CPT Editorial Panel approved the creation of new CPT coding based on the uniqueness, clinical value and widespread use of ImmuKnow, and the fact that existing CPT codes insufficiently captured all steps and costs of testing.

Out of the trillions of "friendly" bacteria - representing hundreds of species -that make our intestines their home, new evidence in mice suggests that it may be a very select few that shape our immune responses. The findings detailed in two October 16th reports appearing in the journals Cell and Immunity, both Cell Press publications, offer new insight into the constant dialogue that goes on between intestinal microbes and the immune system, and point to a remarkably big role for a class of...
