The level of infected mBLats over time in the blood of AIM patients. (A) From the time of initial visit and diagnosis to approximately 1 year for 3 patients. The dotted and unbroken horizontal lines are, respectively, the upper limit and the median values for the blood of healthy carriers (n = 30).19 (B,C) Detailed time course during the first 50 days for 6 patients. The frequency of infected cells (FOIs) is expressed as the percentage of infected memory B cells and is plotted on a log scale to demonstrate the simple exponential decay in the weeks following diagnosis.
