Background
Cytokeratin 18 (CK18) belongs to type-I intermediate-filament family and provides cytoskeletal support for simple epithelia. Expressed in diverse simple epithelia including gastrointestinal, hepatic and pulmonary glandular cells, CK18 heterodimerizes with CK8 to form keratin intermediate filaments, maintaining glandular-epithelial morphology and mechanical resilience. Upon apoptosis, CK18 is proteolytically cleaved into characteristic fragments used for epithelial-cell apoptosis detection. CK18 is a classic glandular-epithelium marker; epithelial-derived tumours commonly retain CK18 expression. Circulating CK18 fragments serve as auxiliary markers for tissue injury. It is widely adopted for epithelial-tissue pathology, glandular-tumour subtyping and epithelial-apoptosis researches.
