The effect of Δ⁹-THC on the T cell-dependent AFC response in vivo in C57BL/6 wild-type and CB₁^−/−/CB₂^−/− mice (five/group), which were treated with Δ⁹-THC or corn oil vehicle for 3 days. On Day 2, mice were injected with sRBC. On Day 6, mice were killed, and the AFC response was assayed. Two separate experiments are shown (A and B). Results are expressed as mean ± sem. * or **, Values that are significantly different from VH at P < 0.05 or P < 0.01, respectively, within each genotype.
