Early increased density of cyclooxygenase-2 (COX-2) immunoreactive neurons in Down syndrome
2017
iNeuroinflammation is one of the hallmarks of Alzheimer's disease. One of the enzymes involved in neuroinflammation, even in early stages of the disease, is COX-2, an inducible cyclooxygenase responsible for the generation of eicosanoids and for the generation of free radicals. Individuals with Down syndrome develop Alzheimer's disease early in life. Previous studies pointed to the possible overexpression of COX-2 and correlated it to brain regions affected by the disease. We analysed the COX-2 expression levels in individuals with Down syndrome and in young, adult and old mice of the Ts65Dn mouse model for Down syndrome. We have observed an overexpression of COX-2 in both, Down syndrome in…
Phenotypic characterization of MCP-1 expressing neurons in the rat cerebral cortex.
2020
Chemokines are small, secreted molecules that mediate inflammatory reactions. Neurons and astrocytes constitutively express chemokines implicated in the process of neuroinflammation associated with neurodegenerative diseases. The monocyte chemoattractant protein-1 (MCP-1) has been widely related to this process. However, the constitutive expression of this molecule by neurons has not been elucidated so far. In this study, we set out to characterize the neurochemical phenotype of MCP-1-expressing neurons in the rat neocortex to infer its role in basal conditions. We observed the presence of two populations of neurons expressing MCP-1: One population of cells with weak expression of MCP-1 cor…
