**Molecular Mechanism and Rationale**
The proposed mechanism centers on alectinib's potential direct interaction with the ITGAM/CD11b subunit of complement receptor 3 (CR3), a critical heterodimeric integrin receptor composed of CD11b (ITGAM) and CD18 (ITGB2) subunits. CR3 functions as the primary microglial receptor for complement component C1q, facilitating the recognition and phagocytic elimination of C1q-opsonized synapses during complement-mediated synaptic pruning.
