Kurloff cells

Kurloff cells are found in the blood and organs of guinea pigs that contain large secretory granules but are of unknown function (also known as Kurloff bodies). They are also found in the capybara. Scientists speculate that these cells along with asparaginase may be what gives the guinea pig cancer resistant properties (Sharon Vanderlip, DVM). The Kurloff cell has NK cytotoxic activity in vitro.
