In addition, reverse transcription‐polymerase chain reaction (RT–PCR) analysis revealed elevated Nrg‐1 and ErbB4 mRNA expression in the phosphatidylserine emulsion‐treated group; high Nrg‐1 and ErbB4 expression levels are associated with better myelination (Liu et al., 2022), while Nrg‐1 gene knockdown in mice lead to schizophrenia‐like behavior (Cong et al., 2022). The gene discussed is ERBB4; the disease is schizophrenia.
