CCS and Alzheimer disease: We used supramaximal concentrations of nifedipine (NIFE, 10 μM), ω-conotoxin-GVIA (GVIA; 1 μM), and ω-agatoxin IVA (AGAIVA; 1 μM), which selectively block the L, N, and P/Q components of inward currents through the VDCCs of CCs [20] to characterize possible differences in their expression related to the progression of AD.
