TABLE 1.

Cytokine production by lymph node cells from mice immunized in the footpads with TSo-pulsed or unpulsed DC or TSo alone^a

Immunization regimen	IFN-γ concn (U/ml)	IL-2 concn (U/ml)	IL-5 concn (U/ml)
DC∼TSo	1,050	0.70	<0.45
DC	<0.9	<0.08	<0.45
TSo	<0.9	<0.08	<0.45

^aMice were injected in the footpads with TSo-pulsed DC (DC∼TSo) or unpulsed DC (DC) or with TSo alone (TSo) or were untreated. Lymph node cells recovered 5 days after immunization were cultured with TSo. The culture supernatants were examined for cytokine production. The peak levels of cytokine in the supernatant are given. Values for IL-2, IFN-γ, and IL-5 were measured at 24, 72, and 96 h of culture, respectively. The results are representative of at least three experiments.
