New discovery suggests novel methods for treating acute lymphoblastic leukemia

Investigators at St. Jude Children's Research Hospital have discovered previously unsuspected mutations that contribute to the formation of pediatric acute lymphoblastic leukemia (ALL), the most common cancer in children.

More evidence that inflammation can fuel cancer

As evidence mounts that the body's normally protective inflammation response can drive some precancerous tissues to become fully malignant, UCSF scientists report discovering an apparent trigger to this potentially deadly process.

Insulin-like growth factor receptor implicated in development of Graves' disease

Investigators at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) have found evidence that continues to implicate insulin-like growth factor receptor (IGF-1R) in the development of Graves' disease.

Scientists find connection between nerve cells and immune system

A direct connection exists between the brain and the immune system – at least in mice. Scientists at the Helmholtz Centre for Infection Research in Braunschweig conducted a comprehensive study of mice intestine and the surrounding blood and lymph vessels using special microscopy and marking techniques.

Scientists discover how T-cell leukemia viruses evade defense mechanisms

National Cancer Institute (NCI) scientists have discovered how human T-cell leukemia virus type 1 (HTLV-1), which infects about 20 million people worldwide, evades being held in check by one of the body's natural defense mechanisms.

Novel approach to synthesizing nanowires

A novel approach to synthesizing nanowires (NWs) allows their direct integration with microelectronic systems for the first time, as well as their ability to act as highly sensitive biomolecule detectors that could revolutionize biological diagnostic applications, according to a report in Nature.

Why organs fail following massive trauma

Massive trauma, say from a sabertooth tiger attack, meant immediate death for the primitive human.

"Allergy cells" can aggravate cancer and psoriasis

The body's mast cells are mainly associated with allergic reaction in the way they release histamine and other inflammatory substances.

New method of gene therapy alters immune cells for treatment of advanced melanoma

A team of researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, has demonstrated sustained regression of advanced melanoma in a study of 17 patients by genetically engineering patients' own white blood cells to recognize and attack cancer cells.

Interaction of proteins in the intestinal system may be allergic indicators

Researchers have identified one of the proteins that may be responsible for causing food allergies, which could lead to the development of more accurate non-invasive tests to identify true food allergies.

SuperGen receives patent for composition and method for treating graft-versus-host disease

SuperGen has announced the issuance of U.S. Patent No. 7,037,900 B2 entitled, "Composition and Method for Treating Graft-versus-Host Disease."

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Inefficient cytotoxic T lymphocyte mediated killing of HIV-1 infected cells in vivo

HIV attacks the immune system by infecting and killing helper T lymphocytes (also called CD4 T cells), the white blood cells responsible for mobilizing the mediators of an immune response.

Children could be saved from neuroblastoma using antibody therapy

Combination of T cell, antibody to neuroblastoma cells and molecule that spurs T cell growth is designed to treat low initial tumor levels or small cancer cell populations that survive initial treatment, according to St. Jude.

Master switch for blood cell development detected

Blood cells develop from blood stem cells in the bone marrow. Their development is regulated by roughly 20 gene regulators or transcription factors.

Zinc supplements safe for chidren with HIV

Zinc-deficient children living in communities where they do not receive adequate amounts of zinc from their diet should be given supplements, even if they are HIV-infected, according to researchers from the Johns Hopkins Bloomberg School of Public Health and other institutions.

Researchers discover the presence of functional ion channels in human embryonic stem cells

These ion channels act like electrical wires and permit ESCs, versatile cells that possess the unique ability to become all cell types of the body, to conduct and pass along electric currents.
