CD4 and bladder transitional cell carcinoma: However, TRPM2 was not correlated with B cells (r = 0.023, p = 6.63e−01), CD8+ T cells (r = −0.049, p = 3.49e−01), CD4+ T cells (r = −0.096, p = 6.73e−02), macrophages (r = 0.031, p = 5.58e−01), neutrophils (r = −0.118, p = 2.49e−02), and dendritic cells (r = −0.042, p = 4.21e−01) in BLCA (Figure 5A).
