Doing God's Work

Note the caption adjacent to the natural killer cell.

Clearly NK cells are well-trained Christian soldiers.

"Onward Christian soldiers marching as to war
With the cross of Jesus going on before.
Christ, the royal master leads against the foe
Forward into battle, see His banners go"

Sounds like inspiration for a new tune from our friend Kevin-Z. I'm hearing a Led-Zepplinesque epic about God's NK and CTL armies battling Satan's tumor cells and their pro-inflammatory macrophage minions. What say you KZ? Do you have the backbone for holy immunology?
