Adenosine deaminase activity during aging. (a) The plasma membrane was obtained from the cerebral cortex of 3-, 6-, and 12-month-old SAMR1 and SAMP8 mice, and adenosine deaminase (ADA) activity was measured as described in the Materials and Methods section. (b) ADA activity measured in the plasma membrane from the cerebral cortex of 4- and 24-month-old C57BL/6J mice. Data are mean ± SEM from three to five different samples. Two-way ANOVA revealed * p < 0.05 is significantly different from the 3-month value; && p < 0.01 is significantly different from the indicated value at 6 months.
