Fig 1. PGRP-LF is mostly expressed in ectodermal derivatives.
(A) PGRP-LFGal4, UAS-nlsGFP larvae showing GFP expression in salivary glands, foregut, hindgut and cuticle and to a lesser extend in fat body. UAS-nlsGFP larvae in a wild-type genetic background is shown as a negative control. (B) Relative PGRP-LF mRNA expression in third instar larvae dissected tissues. mRNA level in whole larvae was set to 100 and values obtained with dissected tissues were expressed as a fold of this value. For (B) histograms correspond to the mean value ± SD of three independent experiments. Values indicated by symbols (*) are statistically significant (t-test, p < 0.05). ns: not significantly different.
