Role of Combined Lipoic Acid and Vitamin D3 on Astrocytes as a Way to Prevent Brain Ageing by Induced Oxidative Stress and Iron Accumulation

Figure 1

Cell viability measured in time-course and dose-response studies in astrocytes. In (a), time-course and dose-response (ranging from 10 μM to 100 μM) studies of LA measured in astrocytes are illustrated; in (b), time-course and dose-response studies of 50 μM LA combined with 100 nM vitD measured in astrocytes are reported. LA = lipoic acid, vitD = vitamin D3, and LA+vitD = combination of lipoic acid and vitamin D3. Data are expressed as (%) of five independent experiments normalized to the control (number 1 in the axis corresponds to 100% control values).
