Glucocorticoids are associated with stress. Here, the authors show that high levels of glucocorticoid stress promote secretory autophagy of matrix metalloproteinase 9 via a stress responsive chaperone, increasing brain-derived neurotrophic factor processing and potentially altering adult synaptic plasticity.
