Mutual interaction between Schwann cells and CD4+T cells promotes the progression of perineural invasion in colorectal cancer [ATAC-seq]
Listed in NCBI GEO
Description
Background
Perineural invasion (PNI) is a common pathological feature associated with poor prognosis of colorectal cancer (CRC). However, the mechanisms underlying PNI formation and its relationship with CD4+T cells within the tumor immune microenvironment remain unclear. Aims: This study investigated the role of CD4+T cells in the development and progression of PNI in CRC by examining the interactions between Schwann cells (SCs), primary glial cells in peripheral nerves, and CD4+T cells.

Methods
Single-cell RNA sequencing, spatial transcriptomics, and multiplex immunohistochemistry were used to profile the characteristics and spatial relationship between SCs and CD4+T cells in PNI CRC tissues. This study established an SCs-CD4⁺T-cells co-culture system and used flow cytometry, transcriptomic sequencing, proteomics, and ATAC-seq to investigate the mechanisms of their interaction. The key findings were validated in mouse models of sciatic nerve invasion and subcutaneous tumor formation.
Finally, the origin of PNI was explored by co-culturing SCs with CRC cells.
