IL4 and infection: To help characterize the immune response in the lung tissue and to compare the pulmonary cytokine signatures of ASCVac-1+MPLA-immunized mice followed by infection with PBS- or adjuvant-immunized mice followed by infection, we quantified the cytokines IL-4, IL-5, IL-6, IL-10, IL-13, and IL-33 in the lung homogenate.
