Representative images from four animals demonstrate detectable amounts of bone marrow macrophages in the brain, although at substantially lower levels than in the liver and spleen. Figure 5.

Macrophages in the spleen marginal zone around the follicles keep the ACs out, acting like the defensive line in football or a "final exclusion barrier," says John Mountz, M.D., Ph.D., professor ...

The spleen is a key component of the immune system. It filters old blood cells, bacteria, tumor cells out of the blood and breaks them down. The macrophages then get rid of them.

In fact, Salmonella often infects macrophages in the spleen, which degrade old or damaged red blood cells. Since red blood cells contain large amounts of iron, the sites of their degradation are ...

After a heart attack in normal mice, leukocyte immune cells in the spleen produce SPMs. However, in the ALX/FPR2-null mice, the researchers found lower levels of SPMs in the heart and the spleen ...

In a study with both rats and healthy people, researchers found that after drinking a baking soda solution for two weeks, the macrophage population shifted from M1, or pro-inflammatory macrophages, to ...

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

After heart attack injury, ALX/FPR2 is activated by resolvin D1 in immune cells in the spleen and in immune cells at the heart attack site. This speeds expedited resolution of the heart attack injury.

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

More than 50 billion cells die in the human body every day, a spectacle of programmed cell death called apoptosis. These cells undergo internal degradation and then fracture into apoptotic bodies ...
