Serum levels of interleukin-33 and its soluble form receptor (sST2) are associated with cognitive performance in patients with schizophrenia

We found a significant correlation between IL-33 and sST2 levels and cognition in schizophrenia. Our results might help in the understanding of how immune markers are associated with cognitive impairment in schizophrenia. It remains to be determined whether the association between IL-33/sST2 and cognition is restricted to patients with schizophrenia.
