Table 3 Scoring for microglial activation

From: Prevention of hypoglycemia-induced neuronal death by minocycline

Score Cell number (cell number per 200 μm × 200 μm) Morphology (% with amoeboid morphology) CD11b intensity
0 0 0% No expression
1 1-20 1-45% Weak
2 21-40 46-90% Average
3 > 40 > 90% High
  1. Microglia were identified by CD11b immunostaining. Scoring with three criteria were combined to yield an aggregate microglial activation score (0 to 9).
