Figure 5. SalB decreases Aβ levels in P. gingivalis-infected mice. The levels of Aβ1-40 (A) and Aβ1-42 (B) were detected in the hippocampus of P. gingivalis-infected mice. Experimental values were expressed as mean ± SEM (n = 6 per group). *P < 0.05, **P < 0.01 vs. Control; #P < 0.05, ##P < 0.01 vs. P.g.
