Employing the TIMER tool, we executed an analysis to investigate the relationship between the expression of the IFI6 gene and diverse immune infiltrates in esophageal carcinoma (ESCA), encompassing B cells, CD4+ T cells, CD8+ T cells, neutrophils, macrophages, B cell receptors (BCR), CD4, CD8A, and CD8B (Figure 7A). The gene discussed is BCR; the disease is carcinoma of esophagus.
