In wild-type mice, ML29 and ML29P50 infection induced slightly lower T-cell responses Notably, in wild-type and STAT-1-/- mice infected either with ML29 or with ML29P50, similar levels of IFN-ɣ-secreting cells were induced after stimulation with GPC cocktails derived from LASV or MOPV. Here, IFNA1 is linked to infection.
