Good question. If you read how that view came to be, it’s from studies e.g. using isolated mitochondria (excluding neuronal and Ddhd2 activity), supplementing short-chain fatty acids, or by comparing beta-ox capacity to cells with robust beta-ox such as astocytes or cardiomyocytes.

💊 Loss of DDHD2-fatty acid pathway causes hereditary spastic paraplegia (HSP54), a childhood-onset neurodegenerative disorder. Excitingly, we found that a combination of activated fatty acids restored neuronal energy and function in HSP54-model neurons, identifying a potential therapy for HSP54. 2/3

Out study suggests that dynamin function at endocytic pits can be essential for infection with single-receptor viruses, while it is not essential but increases uptake and infection efficiency of multi-receptor viruses that otherwise rely on a functional actin network for infection.
