Immunophenotypes in psychosis: is it a premature inflamm-aging disorder?

Area of Science:

• Immunopsychiatry
• Neuroscience
• Pathology

Background:

• The immunopsychiatric field links innate and adaptive immunity to psychotic disorders like schizophrenia.
• Meta-analyses reveal conflicting immunophenotype data in psychotic patients, creating interpretational challenges.
• Immune cell heterogeneity and plasticity complicate understanding their role in psychosis.

Purpose of the Study:

• To review known immunophenotypes in psychosis patients.
• To propose premature immune "burnout" or inflamm-aging as a potential primary mechanism.
• To address the discrepancies in immune cell roles (causal, consequential, beneficial, harmful) in psychosis.

Main Methods:

• Literature review of current immunophenotypes in psychosis.
• Analysis of discrepancies in immune cell findings.
• Theoretical proposal of inflamm-aging as a pathogenic mechanism.

Main Results:

• Evidence suggests immune system involvement in psychosis, but findings are often contradictory.
• Immune cells are highly diverse and context-dependent, complicating direct correlations.
• A unifying hypothesis of early immune dysfunction is presented.

Conclusions:

• Premature immune "burnout" or inflamm-aging, starting from organ development, may underlie psychosis pathogenesis.
• This hypothesis offers a potential explanation for the observed immunophenotype discrepancies.
• Further research into early-life immune programming is warranted to understand psychotic disorders.
