Profiling of autoantibodies in the sera of glioblastoma patients

Aim: This study aimed to determine the expression pattern of autoantibody proteins from the serum of grade IV glioblastoma patients.Materials & methods: We performed high throughput antibody profiling via the Sengenics i-Ome® Protein Array to determine the differentially expressed autoantibodies.Results: The results portrayed that anti-COL4A3BP and anti-HSP90AA1 were among the upregulated autoantibodies in glioblastoma sera.Conclusion: The selected autoantibodies offer promising targets for future glioblastoma pathogenesis. However, further validation is required to elucidate the autoantibody signature in glioblastoma patients.
