Complement C5a is associated primarily with inflammation. The widespread expression of its receptors, C5aR and C5L2 in neuronal cells, however, suggests additional regulatory roles for C5a in the CNS. C5aR agonist (PL37-MAP) evokes Ca(2+)-influx in GT1-7 neuronal cell line and the Ca(2+)-influx is regulated by estradiol. In the present study, we examined(More)
In our earlier results, we demonstrated that cells expressing the complement C5aR are vulnerable since abnormal activation of C5aR caused apoptosis of these cells. In this study, we demonstrate that activation of C5aR by antisense homology box (AHB) peptides synthesized in multiple antigenic peptide form and representing putative interaction sites of the(More)
Dementia is a social problem in Japan, as it is in other countries. Recently, there has been an increase in the number of patients with Alzheimer-type dementia (ATD) in the population. We analyzed 239 cases of patients autopsied at Fukushimura Hospital over a 10-year period. Clinicopathologically, 66% of these cases (158 cases) presented with dementia(More)
