The Heterogeneity of B Cells Potentially Contributes to Metastasis of Clear Cell Renal Cell Carcinomas.

Clear cell renal cell carcinoma (ccRCC) exhibits extensive immune infiltration, yet the influence of immunological heterogeneity on clinical outcomes remains poorly elucidated.

Addressing the formidable challenge of metastasis suppression in ccRCC treatment.

Use scRNA-seq analysis and immunofluorescent imaging to categorize B cells into sub-clusters based on distinct gene expression profiles.

Identify two significant B cell subpopulations, B cell (HLA-DRA) and B cell (FKBP11); show the upregulation of six genes (DERL3, FKBP11, MZB1, TNFSF13B, MYO9B, and ACAP1) in infiltrating B lymphocytes associated with poor prognosis of ccRCC; find that B cell (HLA-DRA) displays a noteworthy association with ccRCC metastasis and demonstrates relevance to tumor immunity across diverse cancers.

The heterogeneity within B-cell subpopulations may substantially contribute to the metastatic potential of clear cell renal cell carcinoma. The findings provide insights into targeted interventions and improved clinical outcomes.
