Macrophages play numerous roles within tumors, leaving cancer researchers with a choice: eliminate the cells or recruit them.

A new study reveals that a constant stream of ink-gobbling immune cells helps hold tattoos in place.

Immune-like cells in the central nervous system are now recognized as key participants in the creation and maintenance of persistent pain.

The acute pain that results from injury or disease is very different from chronic pain.

From guiding branching neurons in the developing brain to maintaining a healthy heartbeat, there seems to be no job that the immune cells can’t tackle.

In addition to circulating in the blood as immune sentinels, macrophages play specialized roles in different organs around the body.

M proteins from Streptococcus bacteria selectively kill mouse macrophages and human macrophage-like cells by prompting cell death.

Science’s lowest common denominator has always been patterns.

Time-lapse imaging shows the immune cells transferring chemical signals during pigment pattern formation in developing zebrafish.

Immune cells called macrophages shuttle cellular messages in the skin.
