Fig. 5. LK neurons function downstream of UNs to mediate increased defensive response in mated females.

Fig. 5

a Putative second order neurons of UNs (red) revealed by trans-Tango (green). Magenta: nc82. Right panel: the abdominal ganglion (Abg) of the VNC was zoomed in. White dashed line outlines the border of the VNC. Scale bar represented 50 μm. b Immunofluorescence of abdominal LK neurons (ABLK) (green) and nc82 (magenta). Scale bar represented 50 μm. c GRASP signal (green) between UNs and LK neurons in the Abg. White dashed line outlines the border of the VNC. Scale bar represented 50 μm. d, e Mutation of the LK gene d or silencing LK neurons with Kir2.1 e blocked the mating-induced defense facilitation. n = 9, 8, 12, 11, 9, 9 (from left to right) in d, n = 10, 10, 8, 8, 9, 8 (from left to right) in e. Error bars indicate mean ± SEM, **p < 0.01, *p < 0.05, p > 0.05 (n.s.), n.s., not significant, two-tailed unpaired t tests. Source data are provided as a Source Data file.
