TABLE 3.

IFN-γ release, in response to PBS or PPD-B, by cells from calves treated with anti-WC1 MAb (depleted) or control MAb (nondepleted)^a

Day	Mean OD ± SEM in response to PPD-B		P	Mean OD ± SEM in response to PBS		P
	Nondepleted	Depleted		Nondepleted	Depleted
−1	0.45 ± 0.12	0.47 ± 0.09	0.47	0.47 ± 0.10	0.41 ± 0.08	0.41
0	0.48 ± 0.13	0.21 ± 0.06	0.03b	0.49 ± 0.15	0.23 ± 0.08	0.12
1	0.53 ± 0.09	0.38 ± 0.09	0.24	0.47 ± 0.10	0.38 ± 0.10	0.15
4	0.46 ± 0.15	0.38 ± 0.16	0.35	0.45 ± 0.15	0.40 ± 0.15	0.24

^aIFN-γ production expressed as mean OD ± standard error of the mean.

^bNo significant differences between animals depleted of WC1⁺ cells and those not depleted of these cells, except on day 0 with PPD-B (P = 0.03).
