MHV-68 titers in the lungs of μMT mice

Treatment	Days after infection
	17	21	29
Undepleted	0.82  ±  0.17	1.15  ±  0.20	0.10  ±  0.17
Anti-CD4	ND	3.12  ±  0.48	2.95  ±  0.47
Anti-CD8	ND	2.68  ±  0.29	0.00  ±  0.00
Anti-CD4/CD8	8.00  ±  0.01	All dead

The μMT mice were dosed i.p. (27, 32) with the GK1.5 and/or 2.43 mAbs every second day, starting 4 days before i.n. infection with 600 pfu of MHV-68. Groups of three or four mice were sampled at different times after virus challenge, and titers are expressed as mean ± SD log₁₀ values of lung homogenates (pfu/ml). ND, not done.
