In adults, 3 proteins (LTF, Cathelicidin, PGLYRP1) had the same representation than in young animals while the other 3 proteins were over-represented in infected TB+ (MHC class I antigen, MHCI; Q8SPA3) or TB++ (Heme peroxidase, LTF) animals when compared to uninfected TB- controls (Fig 4A and 4B). Here, HLA-DQA2 is linked to tuberculosis.
