Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Tofacitinib improves disease activity and inhibits progression of joint damage in RA patients

A Phase 3 clinical trial demonstrates that tofacitinib improves disease activity and inhibits progression of joint damage in rheumatoid arthritis (RA) patients who did not respond to methotrexate (MTX).

Boosting estrogen levels may help reduce urinary infections in menopausal women

Estrogen levels drop dramatically in menopause, a time when the risk of urinary tract infections increases significantly.

Normalizing p62 protein levels in immune system cells could reduce infection in CF patients

New research suggests that lowering excessive levels of a protein in immune system cells could be a strategy to clear an infection that is deadly to patients with cystic fibrosis (CF).

NIH's candidate vaccine safe in treating dengue

A candidate dengue vaccine developed by scientists at the National Institutes of Health (NIH) has been found to be safe and to stimulate a strong immune response in most vaccine recipients, according to results from an early-stage clinical trial sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH. The trial results were published online on January 17 in the Journal of Infectious Diseases.

DFG now extends funding for research on immunological therapy at Charité

The DFG (Deutsche Forschungsgemeinschaft) has now extended the funding of a research association which is located at the Charité - Universitätsmedizin Berlin. The Collaborative Research Centre (SFB) will receive funding in excess of ten million Euros over the next four years.

New apatamer can boost therapeutic effect of cell-based vaccines

A small compound called an aptamer that specifically targets and stimulates a human immune cell can greatly increase the effectiveness of an immunotherapeutic drug designed to destroy malignant or virus-infected cells. The development of a novel apatamer that recognizes activated T-lymphocytes and can boost the therapeutic effect of cell-based vaccines is described in an article in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc. publishers.

BH3-mimetics might be new option for treatment of autoimmune conditions

Melbourne researchers have discovered that the death of immune system cells is an important safeguard against the development of diseases such as type 1 diabetes, rheumatoid arthritis and lupus, which occur when the immune system attacks the body's own tissues.

Tall, thin women face increased risk of infection with nontuberculous mycobacteria

Tall, thin women face a greater risk of infection with nontuberculous mycobacteria (NTM), cousins of the organism that causes tuberculosis, according to researchers at National Jewish Health. Women with NTM infections also showed a weakened immune response associated with their fat cells, in a paper published in the Jan. 15, 2013, issue of The American Journal of Respiratory and Critical Care.

Strong link between mortality and reduced innate immune responsiveness in critically ill patients

Investigators from 15 children's medical centers, including Nationwide Children's Hospital, observed and evaluated critically ill children with influenza to evaluate the relationships between levels of systemic inflammation, immune function and likelihood to die from the illness. The study appears in the January issue of Critical Care Medicine.

Novel way to engineer specialized immune cells targeted by the AIDS virus

Researchers at the Stanford University School of Medicine have found a novel way to engineer key cells of the immune system so they remain resistant to infection with HIV, the virus that causes AIDS.

EBV reactivation can increase risk of heart disease

A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems.

Antibodies essential for dendritic cell maturation

Dendritic cells, or DCs for short, perform a vital role for the immune system: They engulf pathogens, break them down into their component parts, and then display the pieces on their surface.

Oral supplement of live R. Opacus may help pigs stay healthy during weaning

A common type of bacteria may help pigs stay healthy during weaning. In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.

Studies suggest a new approach to treating HIV

A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection.

Golden nanoparticle starves cancer cell to death

How do you annihilate lymphoma without using any drugs? Starve it to death by depriving it of what appears to be a favorite food: HDL cholesterol.

Early treatment during primary HIV infection shows promise

Two papers in The New England Journal of Medicine suggest that starting antiretroviral treatment early after HIV infection is diagnosed may improve patients’ immune response, boosting the initial recovery of the immune system and delaying progression of the disease.

Itch-specific nerve cells: an interview with Associate Professor Xinzhong Dong

Itch was actually defined by a German physician more than 350 years ago. His name was Samuel Hafenreffer. He defined itch as an unpleasant sensation that makes people want to scratch. You probably think this is a very simple definition but itch is really a very complex sensory modality.

Scientists discover role of OTUD7B enzyme as TRAF3's protector

Marked for death with molecular tags that act like a homing signal for a cell's protein-destroying machinery, a pivotal enzyme is rescued by another molecule that sweeps the telltale targets off in the nick of time.
