Abstract

Schizophrenia is a heterogeneous and multifactorial disorder that affects around 21 million people worldwide. The disease is often characterized by the occurrence of positive, negative and cognitive symptoms. Several studies have shown that patients with schizophrenia present high concentrations of inflammatory molecules in the brain. These molecules could cross the blood brain barrier and change the homeostasis of the central nervous system. They can also interact with microglia, triggering an unsuitable inflammatory response in the brain, impairing the role of resident cells. Recent studies have revealed a decrease of microglia activation in animal models treated with clozapine. Although this antipsychotic is the main choice in refractory schizophrenia, clozapine can induce agranulocytosis as side effect, which may lead to death. Thus, here we are going to perform proteomic analyses of microglia cultures treated with the blood serum of schizophrenia patients, in addition to clozapine treatment, allowing the identification of key metabolic pathways to the disorder. The present project is also going to carry out proteomic analyses of clozapine-induced agranulocytosis in an ex vivo model, searching for potential therapeutic targets that could lead to the improvement of patients' health and quality of life.
