Abstract
Saponins are extracted from different parts of plants such as seeds, roots, stems, and leaves and have a variety of biological activities including immunomodulatory, anti-inflammatory effects, and hypoglycemic properties. They demonstrate inherent low immunogenicity and possess the capacity to effectively regulate both the innate and adaptive immune responses. Plant saponins can promote the growth and development of the body's immune organs through a variety of signaling pathways, regulate the activity of a variety of immune cells, and increase the secretion of immune-related cytokines and antigen-specific antibodies, thereby exerting the role of immune activity. However, the chemical structure of plant saponins determines its certain hemolytic and cytotoxicity. With the development of science and technology, these disadvantages can be avoided or reduced by certain technical means. In recent years, there has been a significant surge in interest surrounding the investigation of plant saponins as immunomodulators. Consequently, the objective of this review is to thoroughly examine the immunomodulatory properties of plant saponins and elucidate their potential mechanisms, with the intention of offering a valuable point of reference for subsequent research and advancement within this domain.

Su F, Xue Y, Ye S, Yu B, Li J, Xu L, Yuan X. Integrative transcriptomic and metabolomic analysis in mice reveals the mechanism by which ginseng stem-leaf saponins enhance mucosal immunity induced by a porcine epidemic diarrhea virus vaccination. Vaccine 2023; 41:6379-6390. [PMID: 37704497 DOI: 10.1016/j.vaccine.2023.09.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/31/2023] [Accepted: 09/07/2023] [Indexed: 09/15/2023]
Abstract
Porcine epidemic diarrhea virus (PEDV) is a main cause of severe enteric disease in piglets, leading to millions of dollars lost annually in the global pig industry. Parenteral vaccination is limited in generating sufficient mucosal immunity, which is crucial for early defense against PEDV. Here, we orally administered ginseng stem-leaf saponins (GSLS) to mice before parenteral vaccination and found that GSLS significantly enhanced the phagocytosis of dendritic cells, promoted the activities of CD4+ T cells and increased PEDV-specific IgA antibodies in the intestinal mucosa. Transcriptomic results showed that the altered genes following GSLS treatment were mostly related to the immune response and metabolism. In addition, integrated analysis of the transcriptome and metabolome revealed that the mechanism by which GSLS enhances mucosal immunity may be associated with progesterone-related pathways. Further studies are needed to explore the detailed molecular mechanisms.
