Laboratory study
What was measured
MTT reduction, lactate dehydrogenase release and glucose consumption in RBE4 rat brain endothelial cells exposed to beta-amyloid(25-35) with or without carnosine, beta-alanine, homocarnosine, aminoguanidine or superoxide dismutase.

What the authors reported

Beta-amyloid(25-35) was toxic at 200 microg/mL. Carnosine prevented cell damage completely at 200 microg/mL amyloid and partially at 300 microg/mL. Beta-alanine, homocarnosine, aminoguanidine and superoxide dismutase also partially rescued cells but less effectively than carnosine. The authors attribute protection to anti-glycating and antioxidant actions.

Limits of this study

Immortalised cell line with a truncated amyloid fragment. Abstract only.
