Macrophage News and Research

RSS

A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Starving HIV virus could be the basis for future therapy: Study

In a medical breakthrough researchers at NYU Langone Medical Center and colleagues have shown how some cells in the body can repel attacks from HIV by starving the virus of the building blocks of life.

SAMHD1 protein cuts off raw material that HIV needs to create DNA and replicate

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

Tailoring TB treatment based on a patient's genetic sequence

A gene that influences the inflammatory response to infection may also predict the effectiveness of drug treatment for a deadly form of tuberculosis.

Multiple DNA repair defect in monocytes

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species (ROS).

Leprosy pathogen exploits micro-RNAs to weaken immune response

A team of UCLA scientists has found that the pathogen that causes leprosy has a remarkable ability to avoid the human immune system by inhibiting the antimicrobial responses important to our defenses.

Five scientists named recipients of Damon Runyon-Rachleff Innovation Award for cancer research

The Damon Runyon Cancer Research Foundation announced that five scientists with novel approaches to fighting cancer have been named 2012 recipients of the Damon Runyon-Rachleff Innovation Award.

Alpha-hemolysin may play an unexpected role in UTIs

Researchers from the University of Utah have identified a process by which the most common types of urinary tract infection-causing bacteria are able to trigger bladder cell shedding and disable immune responses. According to this new study, published in the Jan. 19, 2012, issue of Cell Host & Microbe, α-hemolysin, a toxin secreted by many strains of Escherichia coli (E. coli), may play an important, unexpected role during both the establishment and persistence of urinary tract infections.

Vitamin D could prevent age related eye degeneration: Study

A new study showed that increased vitamin D intake can help to prevent age-related diseases, in particular loss of vision and blindness.

Vitamin D supplements can fight against age-related macular degeneration

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have found that vitamin D reduces the effects of ageing in mouse eyes and improves the vision of older mice significantly. The researchers hope that this might mean that vitamin D supplements could provide a simple and effective way to combat age-related eye diseases, such as macular degeneration (AMD), in people.

Intestinal worm infections may not be bad

Intestinal worm infections may not be all bad, according to a new study by William C. Gause, PhD, and colleagues at UMDNJ- New Jersey Medical School. The researchers have found cytokines that help oust intestinal worm infections in mice also soothe associated lung injury and inflammation.

Study identifies netrin-1 as novel target for atherosclerosis

A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries. The research, published online by Nature Immunology on January 8, 2012, explains why cholesterol-laden, coronary artery disease-causing cells called macrophages, accumulate in artery plaques.

Novel target in artery plaque identified as potential therapeutic intervention

A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries.

Study provides hope for stimulating remyelination in MS patients

Scientists at Joslin Diabetes Center, Harvard University, and the University of Cambridge have found that the age-related impairment of the body's ability to replace protective myelin sheaths, which normally surround nerve fibers and allow them to send signals properly, may be reversible, offering new hope that therapeutic strategies aimed at restoring efficient regeneration can be effective in the central nervous system throughout life.
