Hypothetical representation of PrPC-mediated Endo-MT-like change in the TM. Physiological role of PrPC in the TM: (1) PrPC is expressed on the plasma membrane of TM cells. (2) PrPC maintains cell-ECM interactions by stabilizing β1-integrin and other proteins5,7. Pathological implications: (1) Downregulation of PrPC induces (2) aggregation of β1-integrin and (3) upregulation of fibronectin, collagen 1A, α-SMA, vimentin, and laminin, resulting in (4) increase in IOP and possibly POAG. AH: aqueous humor; PM: plasma membrane; Nu: nucleus.
