Comparing 2 hypotheses side-by-side
Selective opening of pannexin-1 hemichannels creates controlled conduits for small mitochondria and mitochondrial components to transfer between adjacent cells without full cytoplasmic continuity.
This hypothesis proposes that age-related TREM2 signaling dysfunction drives microglia into a senescent state that fundamentally rewires astrocyte-microglia communication networks, creating a pathological feedback loop in neurodegeneration. Under normal conditions, TREM2/TYROBP signaling maintains microglial homeostasis and supports neuroprotective astrocyte-microglia cross-talk through regulated release of IL-33, lactate, and ATP. However, during aging, accumulated DNA damage and metabolic stre
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
