abstract="We have previously reported that caffeine prevented sleep deprivation-induced impairment of long-term potentiation (LTP) of area CA1 as well as hippocampus-dependent learning and memory performance in the radial arm water maze. In this report we examined the impact of long-term (4-week) caffeine consumption (0.3 g/L in drinking water) on synaptic plasticity (Alhaider et al., 2010) deficit in the dentate gyrus (DG) area of acutely sleep-deprived rats. The sleep deprivation and caffeine/sleep deprivation groups were sleep-deprived for 24 h by using the columns-in-water technique. We tested the effect of caffeine and/or sleep deprivation on LTP and measured the basal levels as well as stimulated levels of LTP-related molecules in the DG. The results showed that chronic caffeine administration prevented the impairment of early-phase LTP (E-LTP) in the DG of sleep-deprived rats. Additionally, chronic caffeine treatment prevented the sleep deprivation-associated decreases in the basal levels of the phosphorylated calcium/calmodulin-dependent protein kinase II (P-CaMKII) and brain derived neurotrophic factor (BDNF) as well as in the stimulated levels of P-CaMKII in the DG area. The results suggest that chronic use of caffeine prevented anomalous changes in the basal levels of P-CaMKII and BDNF associated with sleep deprivation and as a result contributes to the revival of LTP in the DG region.<p /> <p>Language: en</p>",
