Abstract

The present paper described the immunomodulatory potential of novel nanocurcumin-based formulation enriched with trace elements and vitamins on cyclophosphamide-induced immunosuppression in rat model. Major immune-related assays were monitored such as hemagglutination assay, delayed-type hypersensitivity (DTH) reaction, cellular immune response, IgG, IgE, IgM, cerebrospinal fluid biomarkers, hematological study, antioxidant profile, and lipid biomarkers. Chemical characterization of novel formulation showed retention time (R t ) 18.98 of curcumin, while LC-MS data revealed the presence of the curcumin mass at m/z 369.01 [M + H]+ (calculated for C21H21O6 +, 369.13). This novel formulation exhibited significantly (p ≤ 0.001) increased primary and secondary antibody titer by 72.41% and 33.25%, respectively, while DTH response being improved by 87.50% (p ≤ 0.01). However, CD4+, CD8+, and CD28+ counts were significantly (p ≤ 0.05) increased by 76.46%, 68.21%, and 19.29%, respectively, while the concentrations of IgE, IgM, and IgG were significantly (p ≤ 0.05) increased by 40%, 28.43%, and 38.75%, respectively. CSF biomarkers analysis showed a decreased level of corticosterone, dopamine, serotonin, and tau protein by 29.38%, 51.73%, 29.93%, and 4.87%, respectively. Antioxidant enzymes such as CAT, GPx, and SOD were increased by 43.74%, 49.00%, and 40.84%, respectively, and non-enzymatic component, GSH, was increased by 55.52%. Similarly, free radical LPO was significantly (p ≤ 0.05) decreased by 40.37%, and acute inflammatory marker, MPO concentration, was reduced by 31.14%, compared with the disease control group. In addition, supportive hematology and lipid profile analysis showed promising results with improved overall animal profile. Thus, trace elements in novel formulation can be used in the various pharmacological activities and as dietary supplement due to its wide properties.
