FIG. 9.

GRFT modifies pulmonary cytokine responses to SARS-CoV infection. Tissues were harvested at days 2 (A and B) and 4 (C and D) postinfection, and cytokine responses were assessed by multiplex analysis of tissue homogenates as described in Materials and Methods. Results are shown for sham (PBS alone), GRFT alone, SARS-CoV with GRFT treatment, and SARS-CoV alone. The x axis legend for day 4 applies to the corresponding panels above for day 2. Note differences in scale on left and right panels. Results are presented as means ± standard errors. n = 3/group; *, P ≤ 0.05 by t test.
