Anxious Profile Influences Behavioral and Immunohistological Findings in the Pilocarpine Model of Epilepsy.

Anxiety and epilepsy have a complex bidirectional relationship, where a depressive/anxious condition is a factor that can trigger seizures which in turn can aggravate the depressive/anxious condition. In addition, brain structures such as the hippocampus and amygdala might have a critical relevance in both epilepsy and anxiety. The aim of the present work was to investigate the influence of different anxious profiles to epileptogenesis.

LPS-Induced Systemic Neonatal Inflammation: Blockage of P2X7R by BBG Decreases Mortality on Rat Pups and Oxidative Stress in Hippocampus of Adult Rats.

Neonatal lipopolysaccharide (LPS) exposure-induced brain inflammation has been associated to neuronal injury and facilitates the development of models of neurological disorders in adult rats. The P2X7 receptor (P2X7R) plays a fundamental role in the onset and maintenance of the inflammatory cascade. Brilliant blue G (BBG), a P2X7R antagonist, has been shown to effectively promote neuroinflammatory protection.

c-Jun expression after cerebral hyperstimulation differs between rats and marmosets.

Immediate early genes (IEGs) are a fundamental element in the way we respond and adapt to a variety of stimuli. We have recently reported that IEG response, as measured by c-Fos expression, is different between rodents and primates. Here, we further extend this analysis by assessing the expression of c-Jun, one of the main complements of c-Fos, under the same stimulation protocol.
