Abstract:
Members of tumor necrosis factor (TNF) superfamily have roles in many biological events and pathogenesis of central nervous system (CNS) diseases. A relatively recently found member of this family, TNF-related weak inducer of apoptosis (TWEAK) have importance both in development of pathological CNS processes and as a target for the treatment of these diseases. The aim of this study was to investigate whether TWEAK's plasma levels are different in patients with schizophrenia. For this purpose plasma TWEAK levels of 44 patients diagnosed with schizophrenia and control group of 40 healthy individuals were compared. Although numerical difference was found between TWEAK levels of patients and controls it was not statistically significant. When we tested for female and male patients and controls seperately, TWEAK levels of male patients were significantly lower than male controls. As far as we know this is the first study that investigates levels of TWEAK in patients with schizophrenia. Although we did not find statistically significant results in our study, we believe that difference could be found in future studies with higher number of subjects. Researches with non-studied TNF superfamily members like TWEAK and TNF-related apoptosis-inducing ligand (TRAIL) could contribute to the understanding of immune-cytokine related hypotheses of schizophrenia.
Insights
This study explored tumor necrosis factor-related weak inducer of apoptosis (TWEAK) plasma levels in schizophrenia patients. Male schizophrenia patients showed significantly lower TWEAK levels compared to male controls, suggesting potential immune-cytokine links.
Area of Science:
- Neuroscience
- Immunology
- Psychiatry
Background:
- Tumor necrosis factor (TNF) superfamily members are implicated in central nervous system (CNS) disease pathogenesis.
- TNF-related weak inducer of apoptosis (TWEAK) plays a role in CNS pathological processes and is a potential therapeutic target.
Purpose of the Study:
- To investigate plasma TWEAK levels in individuals diagnosed with schizophrenia.
- To determine if TWEAK levels differ between schizophrenia patients and healthy controls.
Main Methods:
- Plasma TWEAK levels were measured in 44 schizophrenia patients and 40 healthy controls.
- Statistical analysis was performed to compare TWEAK levels between groups.
- Subgroup analysis was conducted for male and female participants separately.
Main Results:
- Overall, no statistically significant difference in plasma TWEAK levels was observed between schizophrenia patients and controls.
- However, male patients with schizophrenia exhibited significantly lower TWEAK plasma levels compared to male controls.
- This is the first study to examine TWEAK levels in schizophrenia patients.
Conclusions:
- While overall TWEAK levels did not differ significantly, the finding in males warrants further investigation.
- Future research with larger cohorts may reveal statistically significant differences.
- Exploring other TNF superfamily members, like TWEAK and TRAIL, could advance understanding of schizophrenia's immune-cytokine hypotheses.
