TLR2 and ovarian carcinoma: Pattern recognition receptors TLR2, 4, and 5 respond to bacterial flagellin (Rutkowski et al. 2015) or LPS (Wang et al. 2020, 2014; Kashani et al. 2020; Kelly et al. 2006; Glezerman et al. 1998; Huleihel et al. 1997; Park et al. 2017; Muccioli and Benencia 2014) and have pivotal roles in driving inflammation in ovarian cancer.
