The authors presented advances in the research on isoform of neural cell adhesion molecule CD56/NCAM, which appears to raise interest not only in biology, but also in clinical medicine. Molecular aspects of its synthesis have been presented and universal features of this protein have been underlined. It appears to play an important role in body homeostasis and especially in the interactions between neural, immune and endocrine systems. In relation to the immune system there are data suggesting significance of local protective and regulatory mechanisms in the liver linked to so called NKT (CD56+) cells. Main sites of prevalence of CD56/NCAM have been indicated both in physiology and pathology, especially in malignancy. CD56/NCAM incidence is common in tumors of neuroectodermal and endocrine origin. Besides it may be expressed on cells of several hemopoetic neoplasms originated both, from lymphoid and myeloid lineage. Moreover, the attention was paid to CD56/ NCAM expression in atypical sites as for example on epithelia of bile ducts in children with extrahepatic biliary atresia and on cells of pancreatic ducts in the course of chronic pancreatitis.

Expression of CD56, also known as the neural cell adhesion molecule (NCAM), in the pancreatic ducts of chronic pancreatitis is considered to represent a regenerative process of the pancreatic duct system. CD56 expression was analyzed in 25 tissue samples of invasive ductal carcinoma without mixed ductal-endocrine carcinoma of the pancreas, and in the surrounding non-cancerous pancreatic tissue. CD56 expression was detected in intercalated ducts (ICDs) of lobules in the pancreatic parenchyma showing chronic inflammation close to the carcinoma, but not in the carcinoma itself, in all cases. CD56 showed strong, diffuse expression in the areas with severe inflammation, but expression was weak in ICDs where the inflammation was mild. We suggested that CD56 expression is degenerative process in pancreatic tissue with chronic inflammation, and that examination of CD56 expression may be helpful in the differentiation of atypical degenerative ducts from cancerous ducts.
