However, when it comes to bladder urothelial carcinoma (BLCA), there has not been a comprehensive investigation into the function and prognostic value of different immune cell types.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We integrated data from more than 2300 BLCA patients across 14 public datasets. Then we analyzed the quantity of 170 different immune cell signatures using the ssGSEA algorithm. Through meta\u2010analysis and univariable Cox analysis, we identified prognosis\u2010associated immune cells and established an immune cell related prognostic signature (IRPS). We then conducted survival analyses to observe the differences in survival across different IRPS\u2010risk groups. Furthermore, based on the DEGs associated with IRPS, we screened for potential targeted therapeutic agents. Finally, we integrated IRPS with clinical features to establish a comprehensive prognostic index (ICPI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Our analysis identified 90 immune cell types that were particularly relevant to BLCA. Then we constructed and validated the IRPS, with high IRPS significantly associated with longer overall survival (HR\u2009=\u20090.73, 95% CI, 0.71\u20130.76,\n                      <jats:italic>p<\/jats:italic>\n                      &lt;\u20090.001). In two independent immunotherapy cohorts (IMvigor210 and GSE78220), patients with high IRPS demonstrated significantly prolonged survival following immune checkpoint inhibitor treatment (\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.035,\n                      <jats:italic>p<\/jats:italic>\n                      =\u20090.019).
