Abstract :

Different putative toxic amyloid beta (A beta) peptides, beta (1-42), beta (1-40) and beta (25-35), were infused (0.75, 1.5 or 3 nmol) in the rat medial septum. Memory deficits were then investigated using the social recognition test. A significant amnesia was observed 4, 7 and 14 days after intraseptal injection of 3 nmol of beta (1-42), beta-(1-40)- and beta (25-35). Lower amounts of beta (1-42) were inactive except 1.5 nmol that disrupted memory 7 days post-treatment. Used as control, the inverted peptide beta (40-1) and the scrambled beta (25-35) were inactive. Using the prolongation procedure, rats infused with 3 nmol of beta (1-40) were still able to recognize the same juvenile. Finally, a daily treatment with the non-peptide neurotrophic compound SR 57746A (10 mg/kg p.o.) over 21 days, prevented the deficits in short-term memory induced by the intraseptal infusion of 3 nmol of either beta (1-40) or beta (25-35). These findings suggest that A beta fragments could impair short-term memory when infused in the rat medial septum, an effect that is prevented by SR 57746A.
