LGALS4 and bacterial infectious disease: Female flies with NPFR knockdown in Tdc2-marked octopaminergic neurons (Tdc2-GAL4) [58] or a pair of oviduct-born pickpocket neurons (ppk-GAL4) [56,59] or in pLB1 cells that mediate egg-lay decrease after bacterial infection (pLB1-GAL4) [57] did not affect the egg-lay reduction observed after 24 hrs of wasp exposure (Fig 7B).
