critique

I notice that while you've provided the context for hypothesis generation (TREM2 signaling, aging, microglial transitions), the actual "THEORIST HYPOTHESES" appear to be missing from the query. I'll conduct the literature searches and then generate hypotheses grounded in the evidence, followed by rigorous critical evaluation.
