TLR2 and urinary bladder cancer: Sabah-Ozcan et al. (2017) also detected significant decreases in the expression of TLR2-7 and TLR10 in bladder cancer but failed to observe changes in the expression of TLR1, TLR8, and TLR9. Ayari et al. (2011) systematically analyze TLR expression in FFPE human bladder cancer tissues.
