We observed reductions during peak infection in Cacna1d (which encodes Cav1.3, a calcium channel allowing for Ca2+ entry through the apical membrane of enterocytes), S100g (which encodes calbindin CB9k, a binding protein that chaperones Ca2+ to move from apical to basolateral membrane in enterocytes), Atp2b2, Atp2b3, Atp2b4 (which encode the plasma membrane Ca2+ ATPase family that extrude Ca2+ into the blood stream across the basolateral membrane), and Slc8a1 (which encodes sodium calcium exchanger, or NCX1, which also plays a role in the extrusion step) (Table 3) [85]. Here, SLC8A1 is linked to infection.
