| Type | MGI:General | Description | Tnfa (TNFalpha) treatment increases leukocyte rolling flux fraction slightly compared to wild-type rolling velocities of leukocytes are slightly greater compared to wild-type mice at times <30 minutes after surgery; >60 minutes after surgery-induced inflammation, rolling velocities are significantly faster than wild-type (58 vs 38 um/second) similar results on rolling velocity are observed with Tnfa-activated rolling as induced by surgical trauma |
