Escherichia coli-induced central nervous system infection and its impact to neurotransmitters' signaling in the host brain.
 Lokočová, Gabriela ; Luptáková, Dominika (advisor) ; Krempaská, Katarína (referee)
Dissemination of microbial pathogens to the central nervous system (CNS) is one of the most severe and life-threatening complications of neurological disorders, especially in neonates. Microbial pathogen-induced CNS meningitis and encephalitis develop through several steps of host-pathogen interactions, including a high level of bacteremia (bacterial blood count >103 mL-1 ), mucosal colonization by the pathogen, microbial invasion of the intravascular space, and inoculation into the cerebrospinal fluid (CSF), leading to penetration of CNS barriers and inflammation of meninges and brain parenchyma. Neuroinfectious diseases are associated with acute changes in mental and motor function that are followed by chronic neurological dysfunction that can persist long after the recovery from the infection event. Increased expression of cytokines and chemokines by brain cells and CNS compartment-dependent infiltration of leukocytes and neutrophils modulate brain metabolism and function via an effect on neuronal signaling by neurotransmitters. This work aims to summarize the current knowledge about the CNS infections induced by Escherichia coli and brain region-specific neuromodulatory changes with focus on the glutamatergic, dopaminergic, and serotonergic pathway that may be further involved in host's...
