Moreover, we confirmed that the expression levels of immunoproteasome subunit correlate with ICT response also when mutational load, tumor purity, IFNγ, and CD8+ T-cell abundance are controlled for via a partial correlation analysis (Kendall tau = 0.26, P < 0.09), pointing to the independent contribution of IP subunits to ICT response. The gene discussed is CD8A; the disease is neoplasm.
