P12 protein influences key cell-signaling pathway

New research shows that a protein produced by a cancer-causing virus influences a key signaling pathway in the immune cells that the virus infects. This stimulates the cells to divide, helping the virus spread through the body.

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma

The genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma. This finding, from investigators at St. Jude Children's Research Hospital, is published in the current issue of Molecular Cell Biology (MCB).

Fasting every other day, while cutting few calories, may reduce cancer risk

New research at the University of California, Berkeley, raises such a possibility. It shows that healthy mice given only 5 percent fewer calories than mice allowed to eat freely experienced a significant reduction in cell proliferation in several tissues, considered an indicator for cancer risk.

Scientists identify immune-system mutation

A team of Fox Chase Cancer Center scientists led by immunologist Dietmar J. Kappes, Ph.D., has identified the genetic mutation that keeps a mouse strain from developing white blood cells, or lymphocytes, called helper T cells. The report by Kappes and his colleagues appears in the Feb. 24 issue of Nature.

Racial differences may play a significant role in determining a patient's response to asthma medications

A new study in the February issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), shows that asthmatic and nonasthmatic African-Americans required higher doses of glucocorticoids to suppress lymphocytes, which play an important role in airway inflammation.

Stem cells transplanted to female foetus

A female foetus with multiple intrauterine fractures, diagnosed as severe osteogenesis imperfecta, was transplanted with HLA-mismatched mesenchymal stem cells (MSCs) in the 32nd week of gestation.

FDA accepts Genmab's Investigational New Drug Application for active rheumatoid arthritis treatment

Genmab announced today the US Food and Drug Administration (FDA) accepted its Investigational New Drug Application (IND) to start a Phase I/II dose escalation trial for HuMax-CD20 to treat patients with active rheumatoid arthritis (RA) who have failed one treatment with one or more disease modifying anti-rheumatic drugs (DMARDs).

Researchers uncover how HIV causes abnormalities in antibody-producing cells

HIV wreaks much of its damage by targeting the “orchestra conductor” of the immune system, a key class of T cells—CD4+ T cells—whose destructive relationship with HIV has been well-studied by AIDS researchers.

Generic tritherapy can be used as a basic treatment for AIDS

A clinical trial, conducted in Cameroon by IRD researchers working with other organizations and supported by the ANRS, has demonstrated that one of the most common combinations currently deployed in Africa, using nevirapine, stavudine and lamivudine, satisfies these criteria.

Epimmune presents SIV vaccine study data showing control of virus despite the presence of viral mutations

Epimmune today presented preliminary data from its ongoing SIV rhesus macaque vaccine study at the AIDS Vaccine 2004 conference in Lausanne, Switzerland.

Novel disease mechanism underlying rheumatoid arthritis

Investigators at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) have identified a novel disease mechanism underlying rheumatoid arthritis that may open the door to new therapies for this and other debilitating autoimmune disorders.

Protein loss plays role in acute T-cell leukemia

The loss of a key protein (Smad3) in a pathway that helps prevent tumors from forming is specific to one form of childhood leukemia, but not to other pediatric and adult forms of leukemia, according to a new study published in the August 5, 2004, New England Journal of Medicine.

Research that directs cancer-killing immune cells against the deadliest brain tumors shows promise

Researchers seeking to direct cancer-killing immune cells against the deadliest brain tumors have three new targets that show promise in laboratory studies and in a Phase I patient trial, according to two articles in the July 15 issue of the journal Cancer Research.

Inexpensive generic fixed-dose combined therapies appears the most suitable solution for treating AIDS in developing countries

The development of simple and inexpensive generic fixed-dose combined therapies appears the most suitable solution for making possible this access to treatments in developing countries with meagre resources.

Access to HIV antiretroviral therapies in the developing world should be a major world health priority

One of the strategies adopted consists in utilizing combinations of fixed doses of generic antiretrovirals, involving three medicinal drugs of two different classes in the same tablet.

Results from study of Rituxan in rheumatoid arthritis show promise

Genentech, Inc., Biogen Idec and Roche have announced that the New England Journal of Medicine published the results of a Phase IIa study showing that two doses of Rituxan® (Rituximab), administered two weeks apart, improved symptoms in patients with moderate-to-severe rheumatoid arthritis (RA) for up to 48 weeks when combined with methotrexate (MTX), compared to MTX alone.

Geneticists determine the lack of chromosomes

A healthy person’s genome contains 46 chromosomes, but an individual cell can contain less. Contemporary methods allow to determine the value of losses rather accurately. The Tomsk researchers’ effort has been supported by the Russian Foundation for Basic Research.

Experimental human monoclonal antibody shows striking benefit in patients with advanced melanoma

Early testing of an experimental human monoclonal antibody showed a striking benefit in patients with advanced melanoma, say researchers at The University of Texas M. D. Anderson Cancer Center, who presented their findings at the annual meeting of the American Society of Clinical Oncology.

Possible breakthrough in AIDS and cancer research

Mayo Clinic researchers have found a way to revive immunity in mice that have abnormal or deficient immune systems. The discovery may lead to a means of restoring immunity to individuals with immunodeficiency diseases such as AIDS and cancer.
