In contrast, TRPM3 currents from the post-COVID-19 condition group were similar to those from the ME/CFS group: both groups had tiny PregS-induced TRPM3 currents and resistance to ononetin (Figure 1G, p = 0.8578; Figure 3C, p > 0.9999), strongly suggesting that ME/CFS and post-COVID-19 condition are associated with impaired TRPM3 function in NK cells. This evidence concerns the gene TRPM3 and COVID-19.
