Why is TYROBP deficiency neuroprotective when TYROBP is an adapter for multiple AD risk receptors?

The abstract shows TYROBP deficiency is neuroprotective despite being required for TREM2, CD33, and CR3 function - receptors associated with AD risk. This counterintuitive finding challenges current understanding of how these immune receptors contribute to AD pathogenesis. Gap type: contradiction Source paper: Deficiency of TYROBP, an adapter protein for TREM2 and CR3 receptors, is neuroprotective in a mouse model of early Alzheimer's pathology.
