Amazing stuff!
"As if immune cells weren’t already weird enough, researchers studying allergic responses in mice have spotted something completely unexpected ... the phenomenon was completely unexpected.
living neutrophils were sitting inside living mast cells ...
“This new understanding of how mast cells and neutrophils work together adds a whole new layer to our knowledge of allergic reactions and inflammation. ..."
This scanning electron microscopy image captures the moment where degranulating mast cells (pseudo-coloured in sepia) attract and start to incorporate living neutrophils (pseudo-coloured in cyan), forming cell-in-cell structures where mast cells trap living neutrophils inside them.
