LCT and infection: Another comparison of LAC miRNAs that changed in response to infection vs. infection plus SP-A2 (1A0) protein rescue in the same sex revealed that, in male mice, 25 miRNAs were differentially expressed (≥2-fold) in response to infection compared to 12 miRNAs in response to infection plus SP-A2 (1A0) protein, and in female mice, 26 miRNAs were differentially expressed (≥2-fold) in response to infection compared to 15 miRNAs in response to infection plus SP-A2 (1A0) protein rescue (Supplementary File 1).
