Single microRNA plays role in innate immune response

Over the last few years scientists have discovered hundreds of microRNAs - tiny RNAs that regulate the expression of protein-coding genes.

Protein found in the saliva of deer ticks prevents the HIV-1 virus from attaching to the surface of T cells

The HIV-1 virus cripples the human immune system by targeting white blood cells called T cells that form the body's first line of defense in fighting infections.

Major milestone in the culturing of human blood stem cells

Patients with leukemia, certain autoimmune diseases and genetic defects such as sickle-cell anemia can be treated with blood stem cells either from a donor's bone marrow or from cord blood - but the supply of effective stem cells often runs short.

Potential new strategy for treating lupus

Immune cells that would normally die in healthy people accumulate in bodies of patients who have lupus and contribute to the disease, according to new Saint Louis University research published in the Feb. 15 issue of Immunity.

Gene chip technology used to distinguish ventilator-associated pneumonia from underlying critical illness

Critically ill patients who need a ventilator to breathe face a high risk of pneumonia.

Post-traumatic stress disorder leads to long-term health problems

Geisinger research finds that veterans suffering from posttraumatic stress disorder (PTSD) are as likely to have long-term health problems as people with chronic disease risk factors such as an elevated white blood cell counts and biological signs and symptoms.

Researchers use embryonic stem cells to develop functioning immune system blood cells

For the first time, researchers have used embryonic stem cells to develop functioning immune system blood cells -- an important step in eventually using embryonic stem cells as an alternative source of cells for traditional bone marrow transplantations.

14 Feb 2008

Discovery that embryonic stem cells can be used to create functional immune system blood cells

A new study demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells, a finding which is an important step in the utilization of embryonic stem cells as an alternative source of cells for bone marrow transplantation.

Study shows that a key protein appears to enable spread of melanoma to the small intestine

A study by researchers at the John Wayne Cancer Institute at Saint John's Health Center has shown that a receptor protein found on melanoma cells appears to facilitate the disease's spread to the small intestine.

Genetic mutations in the Toll-like receptor 4 gene increase risk of preterm birth

Genetic mutations in the Toll-like receptor 4 (TLR4) gene appear to have significant association with inflammatory injury to the placenta and developing baby, researchers from the University of Pittsburgh's department of obstetrics, gynecology and reproductive sciences report at the 28th annual meeting of the Society for Maternal-Fetal Medicine.

New discoveries on what does and doesn't affect immune system

Scientists know that a number of factors can affect the body's immune system: poor diet, certain steroids, chronic stress. Now researchers at Michigan State University have discovered that an appetite-controlling hormone also affects the immune system, while natural versions of certain steroids do not.

Kidney cancer drug attacks a major type of acute myeloid leukemia

A drug used to treat kidney cancer also targets a genetic mutation active in about one third of patients with acute myeloid leukemia (AML), the most common and lethal form of adult leukemia, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan. 29 edition of the Journal of the National Cancer Institute.

Northwestern Memorial trial may wean kidney transplant patients off antirejection drugs

After a transplant surgery, anti-rejection drugs for the organ recipient are a must, but with prolonged use can have serious side effects, including infections, heart disease and cancer.

Experimental procedure induces tolerance to mismatched kidney transplants

Four of five patients participating in a trial of an experimental protocol designed to induce immune tolerance to HLA-mismatched kidney transplants have been able to discontinue immunosuppressive drugs.

Engineers use blood's hydrodynamics to manipulate stem, cancer cells

A tiny, implantable device has pulled adult stem cells out of a living rat with a far greater purity than any present technique.

Brain molecule from endothelial cells may be a new target for treatment of multiple sclerosis

In the February issue of Nature Immunology, the team provides fresh answers concerning the role of novel adhesion molecules in the pathogenesis of MS, a chronic autoimmune disease of the nervous system that affects approximately 55,000 young adults in Canada.

Studies highlight MRSA evolution and resilience

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain USA300 of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.
