Gcn5 and mTORC1 mediated regulation of autophagy controls Drosophila blood cell homeostasis.

Hemocyte-specific modulation of Gcn5 in the Drosophila lymph gland controls autophagic flux and perturbs blood cell homeostasis.

• Why it matters: Blood progenitors in the lymph gland must balance niche-driven stemness and differentiation, and how autophagy is tuned by nutritional and systemic signals remains unclear.
• What they did: Using genetic perturbation in the lymph gland, the study tested Gcn5 and mTORC1 by altering their levels or activity, including chemical intervention to probe mTORC1 effects on Gcn5-linked regulation.
• The result: Autophagy is critical for lymph gland blood cell homeostasis, and mTORC1 activity can perturb hematopoiesis while overriding Gcn5’s effect, with organismal Gcn5 levels responding to dietary shifts.
