Ischaemic, excitotoxic and traumatic brain injuries have been associated with the occurrence of epileptic seizures. Microglia, the principal immune cells in the brain, produce a variety of proinflammatory and cytotoxic factors especially interleukin-1 (IL-1) early after an acute insult. We studied the effect of intracerebroventricularly administered(More)
Seizures are common sequel to brain insults in cases such as stroke, trauma and infection where there is a certain neuroinflammation. Intracerebroventricular (i.c.v.) administration of lipopolysaccharide (LPS) induces an inflammatory state in brain that is used as a model of neuroinflammation. We studied the effect of LPS (0.25 and 2.5 microg/rat, i.c.v.)(More)
OBJECTIVE Identification of key molecular changes occurring during epileptogenesis provides better understanding of epilepsy and helps to develop strategies to modify those changes and thus, block the epileptogenic process. Gap junctional communication is thought to be involved in epileptogenesis. This communication can be affected by changes in expression(More)
Understanding the molecular and cellular mechanisms underlying epileptogenesis yields new insights into potential therapies that may ultimately prevent epilepsy. Gap junctions (GJs) create direct intercellular conduits between adjacent cells and are formed by hexameric protein subunits called connexins (Cxs). Changes in the expression of Cxs affect GJ(More)
OBJECTIVE Frankincense improves memory in different models of learning. However, its influence on models of Alzheimer's disease (AD) has not been studied widely. In the present study, the therapeutic effect of frankincense was evaluated in a model of AD induced by i.c.v administration of streptozotocin. MATERIALS AND METHODS Under stereotaxic surgery, two(More)
