Rabbit Tonsil-associated M-cells Express Cytokeratin 20 and Take Up Particulate Antigen

Telomerase activity, cytokeratin 20 and cytokeratin 19 in urine cells of bladder cancer patients.

AIM OF THE STUDY This work aims to search for markers suitable for the screening of bladder cancer, which should be specific, sensitive, reproducible, non-invasive and at acceptable cost. PATIENTS AND METHODS The study included 50 patients diagnosed as bladder cancer (35 TCC, 15 SCC) of different stages and grades, 30 patients with various urothelial diseases, besides 20 apparently healthy su...

Cytokeratin 20-positive hepatocellular carcinoma

The differential diagnosis between hepatocellular carcinoma (HCC), cholangiocarcinoma (CC) and metastatic colorectal adenocarcinoma (MCA) may be difficult when only based on morphology. For this purpose immunohistochemical analyses are often required, utilizing antibodies directed against CK8-18, Hep-Par1, glypican 3, CK7, CK19, CK20. Here we report a case of a 65-year-old man who presented wit...

4 Cytokeratin 7 and 20 Agnieszka

Cytokeratins (CK or CKs) are the largest complex group of IF proteins. These are proteins, that are crucial in the development and differentiation of epithelial cells, as well as essential for normal tissue structure and function. The first keratin protein nomenclature was published by Moll et al. (1982) and it has been repeatedly updated in recent years (Schweizer et al., 2006). Based on the r...

Preservation of M. gallisepticum Antigen

Rabbit retinal ganglion cells express functional alpha7 nicotinic acetylcholine receptors.

It is well known that cholinergic agents affect ganglion cell (GC) firing rates and light responses in the retinas of many species, but the specific receptor subtypes involved in mediating these effects have been only partially characterized. We sought to determine whether functional alpha(7) nicotinic acetylcholine receptors (nAChRs) contribute to the responses of specific retinal GC classes i...
