During #NeuronalDifferentiation, #organelles dramatically reorganize. #Microtubules are essential tracks for transport. But are they just highways, or can they instruct organelle behavior? Are tubulin modifications a regulatory code that guides organelle position or function? 1/9

Protective ApoE variants support neuronal function by effluxing oxidized phospholipids
Ralhan et al. show that ApoE2 and ApoE3 Christchurch on lipid particles efflux oxidized phospholipids from neurons via the ABCA7 transporter. This reduces the burden of oxidized lipids, which improves lysosomal function and protects neurons from ferroptosis.
