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.

The extremes of BMI a cause for concern in liver transplantation

A recent study by doctors at the University of Washington explained that patients who are significantly underweight or very severely obese prior to liver transplantation are at increased risk of death following transplantation surgery.

Researchers map how staph infections alter immune system

Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions.

Cryo-electron tomography shows immature HIV in 3D

Scientists at the European Molecular Biology Laboratory (EMBL) and the University Clinic Heidelberg, Germany, have produced a three-dimensional reconstruction of HIV (Human Immunodeficiency Virus), which shows the structure of the immature form of the virus at unprecedented detail. Immature HIV is a precursor of the infectious virus, which can cause AIDS.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

The 'hijacking mechanism' of HIV-1 pinpointed

Researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital - along with colleagues at the University of Manitoba and the University of British Columbia - may have found a chink in the armour of the human immunodeficiency virus type 1 (HIV-1), the microorganism which causes AIDS. They have pinpointed the key cellular machinery co-opted by HIV-1 to hijack the human cell for its own benefit.

Antiretroviral therapy earlier yields better clinical outcomes

A clinical trial has demonstrated that HIV-infected adults in a resource-limited setting are more likely to survive if they start antiretroviral therapy (ART) before their immune systems are severely compromised.

Gene transfer technology may lead to an HIV vaccine

A research team may have broken the stubborn impasse that has frustrated the invention of an effective HIV vaccine, by using an approach that bypasses the usual path followed by vaccine developers.

Chronic infection clearly linked to key immunity protein

The reason deadly infections like human immunodeficiency virus (HIV) and hepatitis C never go away is because these viruses disarm the body's defense system.

Clues about how blood forms could yield new strategies for treating blood diseases

Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood.

Caribbean success story - drop in HIV infections in the Dominican Republic

The last decade has seen a sharp drop in HIV infections in the Dominican Republic, resulting largely from reductions in risky sexual behavior, according to a paper in a supplement to the May 1 issue of JAIDS: Journal of Acquired Immune Deficiency Syndromes.

HIV/AIDS expert urges routine HIV testing

Two influential medical organizations, along with researchers at the University of Alabama at Birmingham (UAB), have announced they strongly recommend universal and routine testing for human immunodeficiency virus (HIV) to help curb the AIDS epidemic. HIV infects more than 30 million globally; during last year alone, more than 2 million worldwide died from AIDS, which is caused by HIV.

Early initiation of antiretroviral therapy improves HIV survival rates, study says

The New York Times on Thursday examined a study that found asymptomatic HIV-positive people who delayed antiretroviral treatment until their disease reached an advanced stage faced higher mortality rates than those who initiated treatment earlier.

Australian researchers win bumper grant from Bill Gates for HIV research

Australian researchers have won themselves a bumper grant from the Bill & Melinda Gates Foundation to examine the best way of using drugs to treat HIV.

Circumcision reduces risk of contracting HIV without reducing sexual pleasure

Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury without reducing pleasure or causing sexual dysfunction.

Why an effective vaccine for HIV has proven so elusive

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled.

$45 million public awareness campaign on HIV/AIDS epidemic in U.S.

The U.S. government has announced a $45 million program to fight the HIV/AIDS epidemic.

New HIV drug may help patients not responding to treatment

A potential treatment for HIV may one day help people who are not responding to Anti-Retroviral Therapy, suggests new research published tomorrow in The Journal of Immunology.

1 Apr 2009

New discovery could lead to new methods to block the transmission of HIV

A team of researchers at Mount Sinai School of Medicine and the UC Davis Center for Biophotonics Science and Technology have for the first time captured on video the transfer of human immunodeficiency virus (HIV) from infected to uninfected T cells through structures called virological synapses.

The egg makes sure that sperm don't get too old

In contrast to women, men are fertile throughout life, but research at the Sahlgrenska Academy, University of Gothenburg, Sweden, has now shown that a fertilising sperm can get help from the egg to rejuvenate. The result is an important step towards future stem cell therapy.
