We hypothesize that the effect of LPS in healthy, adult mice in reducing burrowing and open-field activity is largely mediated by COX-1 mediated PGE2 production by microglia. This study did not address the question whether COX-1 activity might have a similar protective PLX3397 nmr role in LPS-induced behavioural changes in mice with an ongoing neurodegenerative disease. The scientific

and commercial interest in modulating disease onset and progression in Alzheimer’s diseases using NSAIDs has been under scrutiny since clinical trials using predominantly COX-2 inhibitors, have produced disappointing results and failed to demonstrate clinical efficacy (Martin et al., 2008). A recent report compared long-term treatment of a wide range of NSAIDs and found that COX-1 inhibitors (ibuprofen, indomethacin, piroxicam) showed protective effect against the onset or progression

of Alzheimer’s disease (Vlad et al., 2008). In the same study, COX-2 selective inhibitors and non-acetylated NSAIDs (salicylates) had no effect. These clinical studies emphasise the possible importance of COX-1 in neuroinflammation. The authors have no financial conflict of interest.

“In the original publication, the wrong antibodies were listed in the section “Methods and patients; 2.4. ELISA”. All experiments

were performed using the R&D DuoSet ELISA Kit which includes the specific antibodies. The antibodies provided Tolmetin with the R&D DuoSet ELISA kit were used exclusively. There was learn more no exchange of antibodies as indicated in the paper. This section should read as below. […] 96-well-plates were coated overnight with 100 μl capture antibody (4 μg/ml, included within the R&D ELISA kit) at 4 °C. After overnight blocking with 1% protease-free BSA and 5% sucrose, 100 μl of sample or standard were incubated overnight at 4 °C. One hundred microliters detection antibody (150 ng/ml, included within the R&D ELISA kit), solved in PBS with 1% protease-free BSA and 2% normal goat serum was added for 2 hr. […] “
“The association between depression and the metabolic syndrome has assumed greater public health importance due to the rapidly increasing prevalence of these disorders during the past two decades (British Nutrition Foundation, 2004, Ford et al., 2002 and World Health Organization, 2008). All relevant longitudinal studies suggest a higher incidence of the metabolic syndrome and/or its components (high waist circumference, high triglyceride level, low HDL level, high blood pressure, and high glucose level) among those with depressive symptoms (Raikkonen et al., 2002, Raikkonen et al., 2007, Goldbacher et al., 2009, Pulkki-Raback et al., 2009, Vaccarino et al., 2008, Vanhala et al., 2009 and Viinamaki et al.
