Although previous research has observed significant upregulation of pyroptosis-related genes such as CASP1 (Caspase-1), NLRP3 (NLR family pyrin domain containing 3), and IL1B (interleukin 1 beta) in the serum of schizophrenia patients, and extensive neuron pyroptosis has been documented in various neuropsychiatric disorders, including Alzheimer’s disease, epilepsy, and multiple sclerosis, the occurrence of neuron pyroptosis in schizophrenia remains uncertain. Here, CASP1 is linked to schizophrenia.
