Immunodeficiency News and Research

RSS

Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease is compromised or entirely absent.

A new monkey model for HIV

By altering just one gene in HIV-1, scientists have succeeded in infecting pig-tailed macaque monkeys with a human version of the virus that has until now been impossible to study directly in animals.

Sangamo BioSciences starts trial of CCR5-ZFP therapeutic to treat HIV/AIDS

Sangamo BioSciences, Inc. has announced that its collaborators at the University of Pennsylvania have opened a Phase 1 clinical trial to evaluate SB-728-T for the treatment of HIV/AIDS.

Gene therapy for rheumatoid arthritis: promising results

Researchers have reported the first clinical evidence that gene therapy reduces symptoms in patients with rheumatoid arthritis, an important milestone for this promising treatment which has endured a sometimes turbulent past.

Potential new target in the war on HIV/AIDS

The study revealed that a variant of a protein involved in HIV pathogenesis can suppress production of an HIV protein, known as Nef. Nef is required for the human immunodeficiency virus to develop into AIDS through a series of complex events involving viral elements and cellular proteins. Nef has never been a target for drug treatment in HIV patients.

Virtuoso cell engineering

University of Michigan researchers have discovered that a key protein in cells plays a critical role in not one, but two processes affecting the development of cancer.

Phase 3 trial begins for Gammagard liquid plus rHuPH20 in primary immunodeficiency patients

Baxter International Inc. and Halozyme Therapeutics, Inc. gas announced the start of a Phase 3 clinical trial of Baxter's Gammagard Liquid [Immune Globulin Intravenous] 10% (IGIV), marketed as KIOVIG in the European Union, with Halozyme's recombinant human hyaluronidase enzyme (rHuPH20, Enhanze Technology) for the treatment of primary immunodeficiency (PID).

Discovery of new genetic cause severe combined immunodeficiency (SCID)

Severe combined immunodeficiency (SCID) is an inherited disease sometimes known as 'Boy in the bubble syndrome', because the patient lacks one or more type of immune cell, making them very susceptible to infections.

Roche's new dual-target HIV-1 test approved in Europe

Roche announced today that its innovative dual-target HIV-1 test has received CE Mark certification, allowing it to be sold for clinical use in the European Union. The COBAS AmpliPrep/COBAS TaqMan HIV-1 Test, v2.0 utilizes a unique design to simultaneously amplify and detect two separate regions of the HIV-1 genome.

Blocking immune receptor molecule improves response to HIV-like virus, prolongs survival in monkeys

By blocking PD-1 (programmed death-1), an immune receptor molecule known to inhibit the immune response to chronic viral infections, scientists have safely and significantly reduced the plasma viral load and also prolonged survival of rhesus macaque monkeys severely infected with simian immunodeficiency virus (SIV), the nonhuman primate version of human immunodeficiency virus (HIV).

Gene therapy used to fight AIDS

The apparent success of a case in which German doctors cured a man of AIDS using a bone marrow transplant comes as no surprise to Gerhard Bauer, a UC Davis stem cell researcher.

GeoVax's HIV/AIDS human vaccine trials to begin in North and South America

GeoVax Labs, Inc. has announced that the launch of its Phase 2a Human Vaccine Trials will take place in twelve sites across North and South America.

Peregrine Pharmaceuticals awarded U.S. patent for anti-viral applications of phospholipid-targeting antibodies

Peregrine Pharmaceuticals, Inc. has announced that the U.S. Patent and Trademark Office has issued U.S. Patent Number No. 7,455,833, which includes broad claims covering anti-viral applications of antibodies that directly bind to aminophospholipids.

Previously unknown regulatory step during HIV replication provides potential new target for HIV/AIDS therapy

A previously unknown regulatory step during human immunodeficiency (HIV) replication provides a potentially valuable new target for HIV/AIDS therapy, report researchers at the Salk Institute for Biological Studies and the University of Wisconsin, Madison.

XDR-TB declining in the U.S.

A new report suggests that the number of cases of extensively drug-resistant tuberculosis (XDR-TB) in the U.S. has declined in the past fifteen years, but new cases continue to be reported, according to the study published in the November 12 issue of JAMA.

Astragalus root plant chemical used to fight HIV

Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division.

New advances in diagnosis and treatment of allergic diseases

Researchers are presenting more than 450 abstracts on investigational findings in the diagnosis and treatment of allergic diseases at the ACAAI Annual Meeting in Seattle, Nov. 6-11. Following are highlights of some key studies in allergy-immunology.

T-cell-based strategy for HIV-1 vaccines still viable option

The question of whether or not to continue to pursue the development of T-cell-based HIV-1 vaccines has been a source of controversy following last year's widely publicized failure of the field's most promising candidate, a vaccine developed by Merck known as V520.

Gene research sheds light on T-cell production

New research, just published by researchers from the University of Georgia, provides the first evidence that a key gene may be crucial to maintaining the production of the thymus and its disease-fighting T-cells after an animal's birth.

The sooner the better when it comes to HIV/AIDS treatment

New research into HIV/AIDS therapy has found that starting treatment with drugs for the AIDS virus may be better sooner than later as victims are more than 70% less likely to die when they started taking cocktails of HIV drugs earlier than currently recommended.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.
