The resultsrevealed upregulation of the MET proto-oncogene receptor tyrosine kinase (MET)and KIT proto-oncogene receptor tyrosine kinase (KIT) in the encephalitis group,while interleukin 1 receptor type 2 (IL1R2) was downregulated compared to thenon-SAE group (Fig. 4C). Here, KIT is linked to encephalitis.
