Using fluorescence microscopy, scientists tracked the uptake of
WGP 3-6 (bright green) by immune cells called macrophages (left).
The macrophages break down the WGP 3-6 into smaller fragments
that bind to the surface of white blood cells called neutrophils
(right), activating these key immune cells to protect the body
against a wide range of challenges. Source: Journal of Immunology
