CaMKII activation in ExWS and ExWOS: Serial comparison between time points. Serial values for the CaMKII activity in individual PANDAS patients having an exacerbation correlating with a streptococcal infection (ExWS, subjects 1–6) and an exacerbation without a streptococcal infection (ExWOS, subjects 7 and 8) are shown in Table 6. Here, CAMK2G is linked to streptococcal infection.
