Using fluorescence microscopy, scientists tracked the uptake of
BetaRight WGP (bright green) by immune cells called macrophages (left).
The macrophages break down the BetaRight WGP 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
