The formation of MDB has been previously reproduced by 3,5-diethoxycarbonyl-1,4-dihydrocollidine or griseofulvin administration which cross-link CK8 by tissue transglutaminase, thus forming an entangled network, from which MDB progressively arise.

Immunofluorescence studies with anti-NMB-1, a Mallory body-specific monoclonal antibody, indicate that this is a sensitive method for recognizing Mallory bodies in cryostat sections of liver from griseofulvin-treated mice or patients with liver disease.
The NMB-1 epitope which facilitates morphologic and clinical detection of Mallory bodies is distinct from cytokeratin and appears to be responsible for its immunogenicity.

Lab Invest. 1984 Mar;50(3):303-12.

The appearance of Mallory bodies in hepatocytes is associated with derangement of the cytokeratin intermediate filament cytoskeleton, at least as revealed by immunofluorescence and suggested by immunoelectron microscopy.

Mallory bodies (MBs) are cytoplasmic filamentous aggregates containing cytokeratin (CK) material.
They occur in hepatocytes of patients with alcoholic liver disease (i.e., alcoholic hepatitis) and can also be induced experimentally in mice by chronic griseofulvin intoxication.

Mice primed by feeding griseofulvin or diethyl 1,4-dihydro 1,4,6-trimethyl 3,5-pyridine decarboxylate for 5 months followed by drug withdrawal for 1 month (drug-primed mice) were given thioacetamide intraperitoneally, and the livers were subsequently studied at intervals up to 7 days.
Mallory bodies were identified by immunoperoxidase stains for ubiquitin and cytokeratin.

To study the molecular structure of Mallory body (MB) proteins we applied infrared spectroscopy of the isolated MBs from livers obtained from autopsied patients with alcoholic cirrhosis and griseofulvin-fed (GF-fed) mice.
The relative amount of beta-sheets was increased compared to the alpha-helices in the MBs, indicating that conformational changes in the cytokeratin peptides of the MBs had occurred.
