Link found between immune system and high plasma lipid levels
04-12-2007 · EurekAlert!Researchers have found an unsuspected link between the immune system and high lipid levels (cholesterol and triglycerides in the blood) in mice. The finding could lead to new ways to reduce the risk of heart disease by lowering elevated lipid levels.

- The molecular signature of loneliness
09-12-2007 · EurekAlert!
People who experience chronically high levels of loneliness show gene-expression patterns that differ markedly from those of people who don't feel lonely, according to a new molecular analysis in the online open access journal Genome Biology. The findings suggest that feelings of social isolation are linked to alterations in immune system activity, which result in increased inflammatory signaling within the body.

- Effective HIV control may depend on viral protein targeted by immune cells
12-17-2006 · EurekAlert!
An effective response of the immune system's "killer" T cells against infection with HIV may depend on exactly which viral protein is targeted, according to an international group of researchers. A new study finds that HIV-infected individuals in whom virus-specific CD8 T cells are targeted against the Gag protein have lower viral levels than do those with CD8 responses directed against other viral proteins.

- Low level of neuronal receptor linked to mild cognitive impairment and Alzheimer's disease
09-04-2007 · EurekAlert!
Results of a new study indicate a strong link between the loss of the neuronal receptor LR11and onset of mild cognitive impairment (MCI), often a harbinger of Alzheimer's disease. The findings also show that levels of LR11 in the brain tissue reflect the severity of cognitive impairment and may predict which individuals will progress to Alzheimer's disease.

- How White Blood Cells Cannibalize Virus-infected Cells
10-06-2006 · ScienceDaily
Researchers at Oregon Health and Science University have demonstrated how certain white blood cells literally eat virus-infected cells while fighting disease at the microscopic level. The research not only helps provide a clearer understanding of the body's immune system, it also offers hope of a new method for gauging vaccine effectiveness.

- Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses
04-18-2007 · EurekAlert!
Hepatitis A and hepatitis C, two otherwise unrelated liver viruses have one important thing in common: a trick for avoiding destruction by the immune system. Both dodge immune attacks by attacking the same protein -- an essential link in a chain of molecular signals that triggers antiviral responses.

- Immune compound blocks virus' ability to hijack antibodies
12-12-2007 · EurekAlert!
Researchers at Washington University School of Medicine in St. Louis have shown that a controversial phenomenon known as antibody-dependent enhancement of infection is suppressed by C1q, a blood-borne immune system compound. The link may give researchers the lead they need to begin untangling a snarl of evidence from decades of puzzling epidemiological and laboratory-based studies of ADE.

- Sleepless for science: Flies show link between sleep, immune system in Stanford study
05-14-2007 · EurekAlert!
Go a few nights without enough sleep and you're more likely to get sick, but scientists have no real explanation for how sleep is related to the immune system. Now, researchers at the Stanford University School of Medicine are finding that fruit flies can point to the answers.
