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.
Research findings could lead to better tests for predicting breast cancer spread

Research findings could lead to better tests for predicting breast cancer spread

A study combining tumor cells from patients with breast cancer with a laboratory model of blood vessel lining provides the most compelling evidence so far that a specific trio of cells is required for the spread of breast cancer. The findings could lead to better tests for predicting whether a woman's breast cancer will spread and to new anti-cancer therapies. [More]

Excess fat in lungs may cause pulmonary fibrosis

Excess fat in lungs may cause pulmonary fibrosis

Pulmonary fibrosis has no cure. It's caused by scarring that seems to feed on itself, with the tougher, less elastic tissue replacing the ever moving and stretching lung, making it increasingly difficult for patients to breathe. [More]
Health benefits of modified formulation of curcumin supplements

Health benefits of modified formulation of curcumin supplements

The health benefits of over-the-counter curcumin supplements might not get past your gut, but new research shows that a modified formulation of the spice releases its anti-inflammatory goodness throughout the body. [More]

Game theory and the cancer ecosystem: an interview with Professor Pienta, Johns Hopkins

The classic description of game theory was described by the prisoner's dilemma, which is a situation in which two players have two options where the outcome depends on the simultaneous choice made by the other. [More]

Discovery offers promising new avenue for prevention, treatment of type 2 diabetes

The surprising discovery of a previously unidentified class of lipid molecules that enhance insulin sensitivity and blood sugar control offers a promising new avenue for the prevention and treatment of type 2 diabetes. [More]
Animal study suggests ibuprofen can reduce lung inflammation in elderly

Animal study suggests ibuprofen can reduce lung inflammation in elderly

New research shows that the lungs become more inflammatory with age and that ibuprofen can lower that inflammation. [More]
Scientists develop unique method to deliver cancer vaccines

Scientists develop unique method to deliver cancer vaccines

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. [More]
Early exposure to marijuana can lead to immune-related diseases in adulthood

Early exposure to marijuana can lead to immune-related diseases in adulthood

When it comes to using marijuana, new research, involving mice and published in the October 2014 issue of the Journal of Leukocyte Biology, suggests that just because you can do it, doesn't mean that you should. That's because a team of Italian scientists have found that using marijuana in adolescence may do serious long-term damage to the immune system. [More]

A new study has revealed how stem cells work to improve lung function in acute respiratory distress syndrome (ARDS). [More]
New breast cancer vaccine provides evidence of immunotherapy in preventing disease recurrence

New breast cancer vaccine provides evidence of immunotherapy in preventing disease recurrence

A new breast cancer vaccine candidate, (GP2), provides further evidence of the potential of immunotherapy in preventing disease recurrence. This is especially the case for high-risk patients when it is combined with a powerful immunotherapy drug. [More]
Scientists identify how immune cells use two critical receptors to clear dead cells from the body

Scientists identify how immune cells use two critical receptors to clear dead cells from the body

In most of the tissues of the body, specialized immune cells are entrusted with the task of engulfing the billions of dead cells that are generated every day. [More]
Investigators make thought-provoking discovery about type of cholesterol believed to be "bad guy"

Investigators make thought-provoking discovery about type of cholesterol believed to be "bad guy"

A team of investigators at the University of Kentucky has made a thought-provoking discovery about a type of cholesterol previously believed to be a "bad guy" in the development of heart disease and other conditions. [More]
Artificial cells to devour undesirables: an interview with Dr. Takanari Inoue

Artificial cells to devour undesirables: an interview with Dr. Takanari Inoue

If junk is not removed, pathological conditions can develop. For example, in one condition, the neutrophil count significantly decreases. Neutrophils remove pathogens and people with a reduced neutrophil count are more prone to infection, especially to rare bacteria that wouldn’t cause infection under normal conditions. [More]

Scientists identify long-overlooked function of vascular smooth muscle cells in atherosclerosis

Scientists at the Interfaculty Institute of Biochemistry (IFIB) have collaborated with colleagues from the Department of Pharmacy and the Department of Dermatology of the University of Tübingen to identify a long-overlooked function of vascular smooth muscle cells in atherosclerosis. [More]
Exploiting chemical response from body's immune system to attack pathogens using copper

Exploiting chemical response from body's immune system to attack pathogens using copper

Harnessing a natural process in the body that pumps lethal doses of copper to fungi and bacteria shows promise as a new way to kill infectious microbes, a team of scientists at Duke University report. [More]

Findings reveal new way to identify non-antibiotic drugs that could help curb bacterial infections

About 100 drugs already approved by the U.S. Food and Drug Administration (FDA) for other purposes can also prevent the growth of certain bacterial pathogens inside human cells, including those that cause Legionnaires' disease, brucellosis, and Mediterranean spotted fever. [More]
