Ecdysone regulates the imaginal disc epithelial barrier, determining the length of regeneration checkpoint delay.

Regeneration of imaginal discs, larval precursors to adult tissues, activates a regeneration checkpoint that coordinates regenerative growth with developmental progression. This regeneration checkpoint results from the release of the relaxin-family peptide Dilp8 from regenerating imaginal tissues. Secreted Dilp8 protein is detected within the imaginal disc lumen, in which it is separated from its receptor target Lgr3, which is expressed in the brain and prothoracic gland, by the disc epithelial barrier.

Starting Conversations toward Inclusion.

Communal discussions on anti-racism and inclusion are crucial to addressing the history of racism in scientific communities. Unfortunately, universities are not universally implementing these conversations. We provide a blueprint for initiating and executing student-led discussions to empower young scientists to take action toward making science more welcoming and inclusive.
