Low vitamin D levels may limit effectiveness of HIV treatment

A University of Georgia researcher has found that low levels of vitamin D may limit the effectiveness of HIV treatment in adults.

Virginia Tech researchers study how specific cytokine influences gene expression patterns in T helper cells

Environment can make all the difference in behavior - even at the cellular level. Scientists at the Virginia Tech Carilion Research Institute have discovered even a small shift in environmental factors can change how a cell in the immune system matures.

Research provides leads for new strategies to develop HIV vaccine

Recent research has yielded new information about immune responses associated with--and potentially responsible for--protection from HIV infection, providing leads for new strategies to develop an HIV vaccine.

First primate model can help researchers to study mother-to-fetus CMV infections

Cytomegalovirus (CMV) is the leading infectious cause of birth defects worldwide, but scientists have been frustrated in their efforts to develop a vaccine to protect against infections.

Special CD4+ T cells appear to inhibit cancer growth, enhance tumor-killing powers of other immune cells

The key to immune-based cancer therapies lies in the ability to exploit some weakness within the tumor and its environment or to elude cancer's offenses. Writing in the journal Scientific Reports, researchers led by a group from the Roswell Park Cancer Institute Center for Immunotherapy have shared new insights about a subset of T cells that appear to do both those things, inhibiting cancer growth at the same time that they enhance the tumor-killing powers of other immune cells.

UTEP researchers patent low-cost device that can easily track health of HIV patients

University of Texas at El Paso researchers have patented a low-cost device that can easily monitor the health of HIV patients living in low-resource settings.

New study broadens understanding of how the immune system responds to flu virus

A new study of influenza infection in an animal model broadens understanding of how the immune system responds to flu virus, showing that the process is more dynamic than usually described, engaging a broader array of biological pathways. The researchers say their findings may offer key insights for designing more effective vaccines in general.

New cell type appears to drive life-threatening food allergies

Researchers have discovered a new cell type that appears to drive life-threatening food allergies and may help explain why some people get severe allergic reactions and others do not.

Researchers show how a cell surface protein can mobilize immune cells to attack malignant tumors

Revealing a biological combat strategy worthy of a five-star general, researchers from Houston Methodist Hospital, University of Chicago and Cornell University have shown how a cell surface receptor--a specialized protein which communicates signals between a cell and the outside world--can mobilize immune cells to attack, rather than protect, malignant tumors.

Caltech researchers find antibody that can detect, neutralize HIV viruses in infected patients

Proteins called broadly neutralizing antibodies (bNAbs) are a promising key to the prevention of infection by HIV, the virus that causes AIDS. bNAbs have been found in blood samples from some HIV patients whose immune systems can naturally control the infection.

Multiple HIV-1 variants at the beginning of infection impact viral load setpoints

HIV-1 infection with multiple founder variants points to poorer clinical outcomes than infection with a single variant, according to a paper published today in the journal Nature Medicine.

Cell-to-cell transmission of HIV leads to development of AIDS

Researchers from the Gladstone Institutes have revealed that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another.

Adaptive immune system plays active role in guiding development of mammary glands

In experiments with mouse tissue, UC San Francisco researchers have discovered that the adaptive immune system, generally associated with fighting bacterial and viral infections, plays an active role in guiding the normal development of mammary glands, the only organs--in female humans as well as mice--that develop predominately after birth, beginning at puberty.

AbVitro launches PairMe Grant Challenge to provide access to AbPair technology

AbVitro Inc., an immuno-oncology discovery company, today announced access to its AbPairTM technology by launching the "PairMe Grant Challenge."

Early exposure to inflammatory cytokines can paralyze CD4 T cells

In a discovery that is likely to rewrite immunology text books, researchers at UC Davis have found that early exposure to inflammatory cytokines, such as interleukin 2, can "paralyze" CD4 T cells, immune components that help orchestrate the body's response to pathogens and other invaders.

PHIV children may lack immunity against measles, mumps, and rubella despite vaccination

Between one-third and one-half of individuals in the United States who were infected with HIV around the time of birth may not have sufficient immunity to ward off measles, mumps, and rubella--even though they may have been vaccinated against these diseases.

Researchers create new cell screening method for immunotherapy cancer treatments

Researchers have created a new method for screening cells used in immunotherapy cancer treatments, allowing high-performing immune system cells to be studied in isolation and potentially expanding the number of patients for whom the breakthrough treatment proves successful.

University of Liverpool study finds that HIV can continue to grow in patients despite treatment

HIV can continue to grow in patients who are thought to be responding well to treatment, according to research by the University of Liverpool.

Research: Critical aspects of human genome's regulatory program encoded by genomic sequence elements

Since the classical studies of Jacob and Monod in the early 1960s, it has been evident that genome sequences contain not only blueprints for genes and the proteins that they encode, but also the instructions for a coordinated regulatory program that governs when, where and to what extent these genes and proteins are expressed.

Researchers uncover master regulators that govern the fate of TFH cells

Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear.
