- Psychoneuroimmunological characterization in schizophrenia requires health-related adjustments.

Schizophrenia is severe and complex. It’s etiology, course, and severity are influe nced by biologica l (e.g., genetic) and psychosocial factors (e.g., urbanicity). Altera tions in cytokine s leve ls (im mune function bioma rkers) were reported in schizophrenia, which related to symptom severity, indicating a potentia l role of im mune activity in this dis order. Cytokine leve ls are influenced by life habits (e.g., smoking), personal characteristics (e.g., sex/ gender), and life conditions (e.g., care access).
