Onset of the specific IFN-γ response.

First row: estimated onset of the specific IFN-γ response taking into account the organ and day on which it appears. The moment at which the 20 SFU threshold would have been surpassed is linearly interpolated between two consecutive experimental points (last point with SFU20). Second row: organ and BL of the organ that would have triggered the IFN-γ response 2.5 days before its estimated appearance (i.e., organ with the highest BL at that moment).
