The role of immuno-inflammatory abnormalities in neuroprogression
Immuno-inflammatory dysfunction has become a well-consolidated contributor to mental illness pathophysiology. A consistent body of evidence supports the involvement of the immune system in symptomatic expression during acute episodes of severe mental illnesses, but also suggests that this system is involved in longitudinal trajectories of disease. Several explanations have been proposed as possible causes of immune-inflammatory abnormalities in severe mental illnesses, including genetic factors, environmental factors, and complex phenomena such as the premature ageing of the immune system (immunosenescence). Considering the heterogeneity in illness trajectories and the remarkable interindividual variation of immune parameters in individuals with mental illness, it is possible that, for each individual, a unique set of factors operates in a complex interaction of causative and moderator agents. A personalized approach to the role of inflammation in neuroprogression is probably the future for prevention and development of disease-modifying interventions.
