New approaches to explore causes of autoimmunity and immune deficiency diseases

A newly identified regulatory process affecting the biology of immune system T cells should give scientists new approaches to explore the causes of autoimmunity and immune deficiency diseases.

SHIP and PTEN enzymes act cooperatively to suppress B cell lymphoma: Study

Lymphoma is a cancer of the immune system. White blood cells divide again and again, spreading abnormally throughout the body. Lymphomas can arise from two types of white blood cells, T cells or B cells, which divide uncontrollably when the molecular mechanisms that keep them in check go awry.

New discovery raises hopes for women with tamoxifen resistance

SCIENTISTS in London have found a potential new way of boosting the effectiveness of the anti-breast cancer drug, tamoxifen.

Major advance in treatment of brain disorders with external genes

In the October 17 issue of Nature Methods, researchers at Thomas Jefferson University describe how they can transfer genes into brain neurons intravenously, using a viral gene delivery vehicle (vector) that causes no side effects.

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.

Drugs that restore mitochondria function may treat Alzheimer's disease at early stages: Research

Before Alzheimer's patients experience memory loss, the brain's neurons have already suffered harm for years. A new study in mouse models by researchers at Columbia University Medical Center has found that the brain's mitochondria, the powerhouses of the cell, are one of the earliest casualties of the disease. The study, which appeared in the online Early Edition of PNAS, also found that impaired mitochondria then injure the neurons' synapses, which are necessary for normal brain function.

New York Stem Cell Foundation names first six NYSCF Investigators

In an expansion of its ongoing effort to promote the next generation of stem cell scientists, The New York Stem Cell Foundation (NYSCF) today named the first six NYSCF Investigators. Each of the NYSCF-Robertson and NYSCF-Helmsley Investigators will receive up to $1.5 million over the next five years to expand their own laboratories, train other scientists and foster innovative high-risk/high reward research to explore the therapeutic potential of stem cells derived from humans and model organisms.

NIH awards La Jolla Institute $12.6M to develop San Diego's first Center for RNAi screening

The La Jolla Institute for Allergy & Immunology will develop San Diego's first Center for RNAi screening -- a breakthrough genomics technology that will further enhance San Diego's reputation as a national research leader and provide the local biomedical community ready access to the Nobel-Prize winning technology.

Role of TGF-ß in cancer diseases

During this year's BIOTECHNICA exhibition, the international biotech news magazine „GEN - Genetic Engineering & Biotechnology News yesterday on 5 October 2010, held an information event with subsequent panel discussion featuring the topic TGF-ß an important target in cancer diseases.

Study on B-cell receptors may help develop new treatment strategies for leukaemia

In order to track down pathogens and render them harmless, the immune system must be able to recognize myriad different foreign substances and react to them. Scientists at the Max Planck Institute of Immunobiology and the Centre for Biological Signalling Studies BIOSS at the University of Freiburg have discovered how the immune system's B-cells can be activated by numerous substances from our environment.

Researchers identify ways to predict embryonic developmental success

Two-thirds of all human embryos fail to develop successfully. Now, in a new study, researchers at the Stanford University School of Medicine have shown that they can predict with 93 percent certainty which fertilized eggs will make it to a critical developmental milestone and which will stall and die. The findings are important to the understanding of the fundamentals of human development at the earliest stages, which have largely remained a mystery despite the attention given to human embryonic stem cell research.

BCBC awards grant for cell therapy research in type 1 diabetes

Maike Sander, MD, associate professor of pediatrics and cellular & molecular medicine at the University of California, San Diego School of Medicine has been awarded nearly $5 million by the Beta Cell Biology Consortium (BCBC) to lead an interdisciplinary team in cell therapy research for type 1 diabetes.

Cell aging is associated with reduced histone level

Like cats, human cells have a finite number of lives-once they divide a certain number of times they change shape, slow their pace, and eventually stop dividing, a phenomenon called cellular senescence.

NIH funds $1.5M for research into prediction of stroke risk in pediatric patients with sickle cell disease

A researcher from the biomedical engineering department operated by Georgia Tech and Emory University has received a $1.5 million NIH Director's New Innovator Award to support a project aimed at reducing the incidence of stroke in children with sickle cell disease. Manu Platt, an assistant professor in the Wallace H. Coulter Department of Biomedical Engineering, will use the National Institutes of Health (NIH) funding to develop models for identifying which children with the disease are at risk for stroke.
