Abstrakt: Patients with impaired immune systems are particularly vulnerable to infections. With the increasing number of immunocompromised patients, it becomes necessary to design studies that evaluate the effects of toxic contaminants that are a part of our daily lives. Simultaneously, the management of these toxic components also becomes essential. Therefore, the present study evaluated the possible protective role of cinnamaldehyde (Cin) against tenuazonic acid-induced mycotoxicosis in the immunosuppressed murine model. Tenuazonic acid (TeA), a toxin usually produced by Alternaria species, is a common contaminant in tomato and tomato-based products. Evaluating the potential toxicity of a hazardous chemical necessitates the use of in vitro, in vivo, and in silico methods. Here, the immunomodulatory effect of TeA was assessed in vitro using mouse splenocytes. In silico docking was carried out for the tumour markers of eight organs and TeA. The haematological, histopathological, and biochemical aspects were analysed in vivo. The sub-chronic intoxication of mice with TeA showed elevated malondialdehyde, reduced catalase, and superoxide dismutase production, along with abnormal levels of aspartate aminotransferase and alanine transaminase. The treatment with Cin prevented TeA-induced alterations of antioxidant defense enzyme activities and significantly forbade TeA-induced organ damage, showing therapeutic effects and toxicity reduction in TeA-induced mycotoxicosis.
