PGRP-LCd07454 mutant adult flies exhibit increased susceptibility to Coxiella burnetii: their post-infection survival rate is significantly reduced compared to wild-type controls.
Mutant animals have a reduced resistance to B.subtilis infection.
PGRP-LC7454 and PGRP-LC7454/Df(3L)29A6 flies show a marked susceptibility to infection by Gram-negative bacteria (Agrobacterium tumefaciens, P.carotovorum.carotovorum and E.cloacae) compared to wild type, but have almost wild-type resistance to infection by Gram-positive bacteria (E.faecalis) or fungi (B.bassiana).
PGRP-LCd07454 has abnormal immune response phenotype, enhanceable by PGRP-LE112
PGRP-LCd07454 is an enhancer of abnormal immune response phenotype of PGRP-LE112
Unlike single mutants, PGRP-LC7454/PGRP-LE112 double mutant animals exhibit a reduced resistance to E.coli and B.megaterium infection, but not E.faecalis and M.luteus infection.
PGRP-LCd07454 is rescued by PGRP-LCd07454/Scer\GAL4hs.PB
Overexpression of PGRP-LC (by driving expression from the Scer\UAS sequences present in the P{XP}PGRP-LC7454 insertion using Scer\GAL4hs.PB) rescues the susceptibility of PGRP-LC7454 flies to infection by E.cloacae.
Excision of the P{XP} element can revert the susceptibility of PGRP-LC7454 flies to E.cloacae infection.
