Exhaustion Renders Immune Cells Less Effective In Cancer Treatment

May 11, 2012
Rather than stimulating immune cells to more effectively battle cancerous tumors, treatment with the protein interleukin-12 (IL-12) has the opposite effect, driving these intracellular fighters to exhaustion, a Mayo Clinic study has found. The findings appear in the Journal of Clinical Investigation. The study helps explain the negative results of ...

Rutgers team discovers novel approach to stimulate immune cells

May 11, 2012
(Rutgers University) Rutgers researchers have uncovered a new way to stimulate activity of immune cell opiate receptors, leading to efficient tumor cell clearance. The researchers have been able to take a new pharmacological approach to activate the immune cells to prevent cancer growth through stimulation of the opiate receptors found ...

Autoimmunity In Rheumatoid Arthritis Tempered By Regulatory Immune Cell Diversity

May 10, 2012
Untangling the root cause of rheumatoid arthritis has been a difficult task for immunologists, as decades of research has pointed to multiple culprits in our immune system, with contradictory lines of evidence. Now, researchers at The Wistar Institute announce that it takes a diverse array of regulatory T cells (a ...

New screening technique yields elusive compounds to block immune-regulating enzyme

May 10, 2012
(Scripps Research Institute) Scientists at the Scripps Research Institute have found the first chemical compounds that act to block an enzyme that has been linked to inflammatory conditions such as asthma and arthritis, as well as some inflammation-promoted cancers.

Regulatory immune cell diversity tempers autoimmunity in rheumatoid arthritis

May 8, 2012
(The Wistar Institute) To stop rheumatoid arthritis, it takes the collective efforts of a diverse array of regulatory T cells and not just a T cell primed to handle the disease-causing self-antigen, according to Wistar researchers.

Versatile Immune Cells Play Dual Roles In Human Skin

May 7, 2012
A new study helps to resolve an ongoing controversy about whether Langerhans cells (LCs) in human skin function to suppress the immune response and promote tolerance to normal human skin and its "friendly" microbial flora or mobilize a lethal attack against harmful foreign invaders. The research, published online in the ...

Rituximab promotes long-term response for patients with immune destruction of platelets

May 7, 2012
(American Society of Hematology) A new analysis concludes that rituximab, a drug commonly used to treat blood cancers, leads to treatment responses lasting at least five years in approximately one quarter of patients with low platelet counts and a risk of bleeding due to chronic immune thrombocytopenic purpura. In study ...

Seeking Molecular Markers To Identify Breast Cancer Patients Who Would Benefit Most From Immune Suppressant

May 6, 2012
A new analysis may help doctors identify breast cancer patients who will benefit from treatment with the immune suppressant drug everolimus, say French researchers at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium. Everolimus is currently used as an immunosuppressant to prevent patients rejecting transplanted organs and in the ...

Why The Immune System Fails To Kill Breast Tumors In Mice

May 5, 2012
A pioneering approach to imaging breast cancer in mice has revealed new clues about why the human immune system often fails to attack tumors and keep cancer in check. This observation, by scientists at the University of California, San Francisco (UCSF), may help to reveal new approaches to cancer immunotherapy. ...
