description <p dir="ltr">Colorectal cancer (CRC) is influenced by infiltration of immune cell populations in the tumor microenvironment. While elevated levels of cytotoxic T cells are associated with improved prognosis, limited studies have reported associations between CD4<sup>+</sup> T cells and disease outcomes. We recently performed transcriptomic profiling and comparative analyses of sorted CD4<sup>+</sup> and CD8<sup>+</sup> tumor-infiltrating lymphocytes (TILs) from bulk tumors of CRC patients with varying disease stages. In this study, we compared the transcriptomes of CD4<sup>+</sup> with CD8<sup>+</sup> TILs. Functional annotation pathway analyses revealed the downregulation of inflammatory response-related genes, while T cell activation and angiogenesis-related genes were upregulated in CD4<sup>+</sup> TILs. The top 200 deregulated genes in CD4<sup>+</sup> TILs were aligned with the cancer genome atlas (TCGA) CRC dataset to identify a unique gene signature associated with poor prognosis. Moreover, 69 upregulated and 20 downregulated genes showed similar trends of up/downregulation in the TCGA dataset and were used to calculate “poor prognosis score” (ppScore), which was significantly associated with disease-specific survival. High ppScore patients showed lower expression of Treg-, Th1-, and Th17-related genes, and higher expression of Th2-related genes. Our data highlight the significance of T cells within the TME and identify a unique candidate prognostic gene signature for CD4<sup>+</sup> TILs in CRC patients.</p><p><br></p><h2>Other Information</h2><p dir="ltr">Published in: Vaccines<br>License: <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.3390/vaccines9040334" target="_blank">https://dx.doi.org/10.3390/vaccines9040334</a></p>
