Astrocyte-Neuron Metabolic Coupling

From Analysis:

Why do systemic anti-inflammatory drugs fail in AD despite cardiovascular efficacy if neuroinflammation is central?

The debate noted clinical failures of TNF-α and IL-6 inhibitors in AD despite their cardiovascular success and shared inflammatory pathways. This paradox suggests unknown mechanistic differences that could inform therapeutic design.
