Immunohistochemical expression of CD 14 in transitional cell carcinoma of the urinary bladder

CD14 is a co-receptor for bacterial lipolysaccharide (LPS) detection. It is found on myelomonocytic cells such as monocytes, macrophages, and Langerhans cells, CD14 expression in bladder cells is necessary for cytokine secretion and increased tumor growth. The goal of this study was to use immunohistochemistry (IHC) to assess CD14 expression in patients with transitional cell carcinoma of the urinary bladder in order to see if there was a link between CD14 marker expression in bladder cancer and cystitis. The immunoexpression of CD14 in paraffin sections from 30 bladder biopsy samples was separated into three groups: cystitis, low grade bladder cancer (L.G), and high grade bladder cancer (H.G), and studied using immunohistochemical assays (IHC). For bladder cancer (L.G & H.G), the percentage of samples that gave positive results for IHC/CD14 expression was 70% and 80%, respectively, compared to 30% for cystitis. The incidence of study samples appear in both sexes
