Induction of DIMs in mutants with alterations in their immune response. The MALDI-TOF mass spectra of hemolymph from control and 24-h bacteria-challenged (BC 24 h) Drosophila of the imd (A), wild-type (B), Toll10b (C) and Toll− (D) strains were obtained in the linear mode by using NC and 4HCCA in the sample preparation, as reported in Materials and Methods. The DIMs numbered from 1 to 20 are reported and ▾ represents a molecule at m/z 4,620 induced after a bacterial challenge in the hemolymph of Toll10b and Toll− mutant flies.
