Abstract

Abstract: This study explores the effects of a composite probiotic yogurt on the immune function of mice with immune suppression induced by cyclophosphamide. Fifty ICR mice were randomly divided into a control group（NC）, a model group （MC）, a low-dose group（LPYC, concentration: 10⁹ CFU/250 g）, a medium-dose group（MPYC, concentration: 10¹⁰ CFU/250 g）, and a high-dose group（HPYC, concentration: 10¹¹ CFU/250 g）. The study measured the mouse weight, organ index, morphology of the spleen tissue, expression levels of immunoglobulins and immune cell factors, to investigate the effects of probiotic yogurt on immune function. The results showed that the mouse weight growth of the MPYC group and HPYC group was significantly higher than that of the MC group（P<0.05）, but lower than that of the NC group（P>0.05）. The spleen and thymus index of the LPYC, MPYC, and HPYC groups were significantly higher than that of the MC group（P<0.05）, but significantly lower than the weight gain of the NC group mice（P>0.05）. HE staining showed that composite probiotic yogurt improved the morphology of the spleen tissue. ELISA showed that compared with the MC group, composite probiotic yogurt significantly increased the expression of immunoglobulin IgG and IgA in mouse serum（P<0.05）. qRT-PCR results showed that composite probiotic yogurt significantly increased the expression of immune cell factors TNF-α, IL-6, and IL-12 in mouse serum （P<0.05）. In conclusion, composite probiotic yogurt has a significant effect on improving the immune function of immune- suppressed mice.
