Cell cultures are characterized by their simplicity, controllability, and ability to provide detailed basic information on how a particular cell population responds to specific stimuli or insult. These characteristics led to their extensive application in the study of molecular interactions and represent a valuable tool in the study of different pathologies. However, due to the lack of interactions between the different components that form an in vivo system, the results obtained in pure cell cultures not always translate what occurs in vivo. In this context, the use of co-cultures has the advantage of allowing the study of interactions between different types of cells present in a tissue, which in many situations are determinant for the effects obtained. The present study aimed to characterize cortical neuron-glia and neuron-enriched primary cultures and evaluate their response to an ischemic insult. Cell viability was assessed by the MTT assay and cell number/phenotype was analyzed by immunocytochemistry in control cultures and in cells subjected to 4 h of oxygen and glucose deprivation. The results obtained demonstrate that astrocytes have a substantial impact on the injury induced by an ischemic insult, thus suggesting that the crosstalk between glia and neurons is crucial to the neuronal protection in conditions of ischemia.

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte-microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined.

Post-traumatic epilepsy (PTE) is one of the most common life-quality reducing consequences of traumatic brain injury (TBI). However, to date there are no pharmacological approaches to predict or to prevent the development of PTE. The P2X7 receptor (P2X7R) is a cationic ATP-dependent membrane channel that is expressed throughout the brain.

Background: Serovar Typhimurium (. Typhimurium) infection can cause inflammation and oxidative stress in the body, leading to gastroenteritis, fever and other diseases in humans and animals. More and more studies have emphasized the broad prospects of probiotics in improving inflammation and oxidative stress, but the ability and mechanism of (LA) to alleviate the inflammatory/oxidative reaction caused by pathogens are still unclear.

Introduction: In sports, 80% of all ankle injuries are sprains of the external compartment. Functional bandages are usually used preventively, specially in individuals with a history of lateral ankle injuries. To this day, the actual benefits of such taping remain unknown as important modifications are introduced in the ankle biomechanics.
