Scientists identify new mechanism that turns CD4 helper T lymphocytes into killer cells

A research team led by the La Jolla Institute for Allergy & Immunology has discovered the mechanism that enables CD4 helper T cells to assume the more aggressive role of killer T cells in mounting an immune attack against viruses, cancerous tumors and other damaged or infected cells.

As Obama takes oath again, health law's fate rest with others

Obamacare is going into effect next year for real - but what happens with President Barack Obama's signature achievement in his second term is largely out of his hands. The biggest piece of the law - the expansion of coverage to as many as 30 million uninsured Americans - will begin in 2014. Obama may not say a word about that in his inaugural address.

Mature CD4+ helper T lymphocytes can be re-programed to gain killing functions

The fate of mature T lymphocytes might be a lot more flexible than previously thought. New research from the RIKEN Center for Allergy and Immunology (RCAI) in Japan and La Jolla Institute for Allergy and Immunology (LIAI) in the USA shows for the first time that mature CD4+ helper T lymphocytes can be re-programed to become killer-like CD8+ T lymphocytes and gain killing functions.

Study refocuses on how neuroblastoma tumors evolve in response to medicine and other factors

An extensive genomic study of the childhood cancer neuroblastoma reinforces the challenges in treating the most aggressive forms of this disease. Contrary to expectations, the scientists found relatively few recurrent gene mutations—mutations that would suggest new targets for neuroblastoma treatment. Instead, say the researchers, they have now refocused on how neuroblastoma tumors evolve in response to medicine and other factors.

Researchers identify and test first blood-based circulating miRNA biomarkers for Parkinson's

Parkinson's disease (PD) is a progressive neurological condition. At present, it is usually diagnosed only when motor features are present. Hence, there is a need to develop objective and measurable biomarkers to improve PD diagnostics during its earlier stage, prior to its motor onset. In this pilot study, researchers identified and tested the first blood-based circulating microRNA (miRNA) biomarkers for PD.
