Abstract

One hundred mice were randomly divided into five groups. The mice in one group were injected with physiological saline as the normal control group. The mice in the other four groups were injected with physiological saline, sulfated Chuanminshen violaceum polysaccharides (SCVP), Chuanminshen violaceum polysaccharide (CVP) and astragalus polysaccharide (AP) once daily for 7 d and then with cyclophosphamide (CY) in the last 3 d. The serum cytokine level, apoptosis protein expressions, spleen lymphocyte proliferation, changes in peripheral blood T-cell subsets, and immune organ index were then measured. Results showed that SCVP and CVP can overcome CY-induced immunosuppression by promoting spleen lymphocyte proliferation, raising serum IFN-γ and IL-2 levels, enlarging immune organ indexes, and decreasing excessive apoptosis. Moreover, SCVP and CVP showed the potential to treat autoimmune diseases based on CD4(+)/CD8(+) ratios. Results suggested that SCVP and CVP exhibited the potential to treat autoimmune and immunosuppression diseases.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
