Roles of CEACAM1 in cell communication and signaling of lung cancer and other diseases

Abstract

Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a broadly-expressed immunoglobulin-like cell adhesion molecule with a wide range of biological functions to regulate cell signaling. The present article mainly focuses on the role of CEACAM1 as a therapeutic target in lung diseases and discusses the potential of therapeutic strategies targeting CEACAM1. The article overviews the structure and its sub-types, biological function, and potential roles of CEACAM1 in lung diseases. Alterations of CEACAM1 expression and CEACAM1-S/CEACAM1-L ratio promote the growth and metastasis of non-small cell lung carcinoma (NSCLC). Moreover, CEACAM1 mediates bacterial adherence and transcellular transcytosis, resulting in the suppression of immune cell activities and inflammatory responses, which may trigger acute exacerbation of chronic obstructive pulmonary disease (AECOPD). CEACAM1 plays a critical role in the development of NSCLC and AECOPD and can be a diagnostic biomarker and therapeutic target in lung diseases.
