AI Article Synopsis
- Active polysaccharides were extracted from Brassica rapa L. (BRP), with structural characterization indicating it is an acidic heteropolysaccharide composed primarily of Ara, GalA, and GlcA.
- The study found that BRP effectively improved immune functions in cyclophosphamide-induced immunosuppressed mice by boosting thymus and spleen indices, enhancing immune cell activity, and increasing antioxidant levels.
- BRP also elevated serum cytokines and immunoglobulins, influenced key immune signaling pathways, and modified the composition of intestinal microbiota, suggesting its potential as a natural immunomodulator.
Article Abstract
In this paper, active polysaccharides were extracted from Brassica rapa L. polysaccharide (BRP), and structural characterization was preliminarily investigated. Its immunomodulatory activity and molecular biological mechanisms in cyclophosphamide-induced immunosuppressed mice were also explored, as well as its effects on intestinal microbiota. Results indicate that BRP is an acidic heteropolysaccharide with the main components of Ara, GalA, and GlcA and has α- and β-glycosidic linkages with pyranose bonds. The results of the study showed that BRP could effectively improve the thymus and spleen indices and repair Cy-induced immune tissue damage in immunosuppressed mice. Meanwhile, BRP increased the immune cell activity and antioxidant levels in mice. In addition, BRP increased the secretion of cytokines (IL-1β, IL-6, IL-10, and TNF-α) and immunoglobulins (IgA, IgG) in mouse serum. It also regulates the relative expression of genes related to the TLR4/NF-κB signaling pathways as well as regulates the diversity and composition of mouse intestinal microbiota. In conclusion, BRP was able to regulated the immune function in immunosuppressed mice, providing a theoretical basis for the development of immunomodulators.

This study aimed to investigate the effects of dietary isatidis root polysaccharide (IRP) on diarrhea, immunity, and intestinal health in weanling piglets. Forty healthy piglets were randomly assigned to five groups receiving varying dosages of IRP. The findings indicated that different concentrations of IRP significantly reduced diarrhea scores ( < 0.

The mucosal surfaces of the body are the most vulnerable points for infection because they are lined by single or multiple layers of very active epithelial cells. The main protector of these cells is the mucus system generated by the specialized goblet cells secreting its main components, the gel-forming mucins. The organization of the mucus varies from an attached mucus that is impenetrable to bacteria in the large intestine to a nonattached, more penetrable mucus in the small intestine and airways.

Gut dysbiosis serves as an underlying risk factor for the development of hypertension. The resolution of this dysbiosis has emerged as a promising strategy in improving hypertension. Food-derived bioactive protein peptides have become increasingly more attractive in ameliorating hypertension, primarily due to their anti-inflammatory and anti-oxidant activities.

The negative impact of repeated-mild traumatic brain injury (rmTBI) is profoundly seen in circadian-disrupted individuals. The unrelenting inflammation, glial activation, and gut dysbiosis are key neuropathological aberrations in the aftermath of rmTBI. In this study, we examined the impact of chitosan lactate (CL) on circadian disturbance (CD) + rmTBI-generated neurological dysfunctions and its prebiotic response on the gut-brain axis.

Aging is a complex and universal process marked by gradual functional declines at the cellular and tissue levels, often leading to a range of aging-related diseases such as diabetes, cardiovascular diseases, and cancer. Delaying the aging process can help prevent, slow down, and alleviate the severity of these various conditions, enhancing overall health and well-being. Alpha-glucosidase inhibitors (AGIs) are a class of widely used antidiabetic drugs that inhibit alpha-glucosidase in the small intestinal mucosa, delaying carbohydrate absorption and reducing postprandial hyperglycemia.
