Bamburg less Medicine, Biology TLDR It is shown that proinflammatory cytokines (TNF a, IL-1 b, IL-6) also induce rods at the same rate and within the same neuronal population as A b d/t. Abstract Neurites of neurons under acute or chronic stress form bundles of filaments (rods) containing 1:1 cofilin:actin, which impair transport and synaptic function. Rods contain disulfide cross-linked cofilin and are induced by treatments resulting in oxidative stress. Rods form rapidly (5–30 min) in . 80% of cultured hippocampal or cortical neurons treated with excitotoxic levels of glutamate or energy depleted (hypoxia/ischemia or mitochondrial inhibitors). In contrast, slow |
