Temporal patterns of microglial activation when bilirubin enters into the brain
Silva, SL; Osório, CC; Vaz, AR; Barateiro, A; Falcão, AS; Brito, MA; Fernandes, A; Silva, RFM; Brites, DMicroglia turns into an activated state when facing injury and disease entailing two main functions: phagocytosis of cellular debris and propagation of immune response. Once unconjugated bilirubin (UCB) increases proinflammatory cytokine secretion by both astrocytes [1] and microglia [2], we aimed to assess the sequence of events involved in microglia immunophenotype by UCB.

Fernandes, A; Falcao, AS; Silva, RFM; Gordo, AC; Gama, MJ; Brito, MA; Brites, DDuring neonatal hyperbilirubinaemia, astrocytes activated by unconjugated bilirubin (UCB) may contibute to brain toxicity through the production of cytokines. As a first step in addressing the signal transduction cascades involved in the UCB-induced astro
Dissociated primary nerve cell cultures as models for assessment of neurotoxicity
Silva, RFM; Falcao, AS; Fernandes, A; Gordo, AC; Brito, MA; Brites, DExogenous and endogenous neurotoxins may have poisoning effects on living organisms. Neurotoxic signs can result from human intoxication by substances present in natural ecosystems as pollutants, such as inorganic mercury, cadmium, manganese and lead. or
Bilirubin-induced immunostimulant effects and toxicity vary with neural cell ty...
Falcao, AS; Fernandes, A; Brito, MA; Silva, RFM; Brites, DHyperbilirubinemia remains one of the most frequent clinical diagnoses in the neonatal period. The increased vulnerability of premature infants to unconjugated bilirubin (UCB)-induced brain damage may be due to a proneness of immature nerve cells to UCB-t
