Cytokine mRNA levels in the lungs of four strains of inbred mice 14 days after infection with C. immitis^a

Cytokine	Valueb for mouse strain:
	D2	B6	BALB/c	CAST/Ei
IL-10	5.2 × 103	4.2 × 105	1.1 × 105	1.9 × 105
IL-4	1.7 × 104	6.2 × 104	3.5 × 105	9.0 × 104
IL-6	1.6 × 105	3.2 × 105	NDc	ND
IL-2	5.0 × 103	4.0 × 104	ND	ND
IL-12 p40	6.0 × 104	1.4 × 104	5 × 104	6.2 × 104
IFN-γ	1.7 × 105	1.1 × 105	9.0 × 105	8.5 × 105
TNF-α	1.5 × 105	1.0 × 106	5.6 × 105	6.4 × 105

^aCFU in lungs were as follows: D2, 8.6 × 10³; B6, 2 × 10⁶; BALB/c, 8.1 × 10⁵, CAST/Ei, >2 × 10⁶. Values are geometric means for surviving mice; there were 10 mice in each group initially.
