Equine colostral carbohydrates reduce lipopolysaccharide-induced inflammatory responses in equine peripheral blood mononuclear cells
Equine Veterinary Journal , Volume 44 - Issue SUPPL. 43 p. 68- 72
Reasons for performing study: Increasing evidence suggests that reactions to lipopolysaccharide (LPS), particularly in the gut, can be partly or completely mitigated by colostrum- and milk-derived oligosaccharides. Confirmation of this hypothesis could lead to the development of new therapeutic concepts. Objectives: To demonstrate the influence of equine colostral carbohydrates on the inflammatory response in an in vitro model with equine peripheral blood mononuclear cells (PBMCs). Methods: Carbohydrates were extracted from mare colostrum, and then evaluated for their influence on LPS-induced inflammatory responses in PBMCs isolated from the same mares. mRNA expression of tumour necrosis factor-α, interleukin-6 and interleukin-10 was measured as well as the protein levels of tumour necrosis factor-α (TNF-α) and interleukin-10 (IL-10). Results: Equine colostral carbohydrates significantly reduced LPS-induced TNF-α protein at both times measured and significantly reduced LPS-induced TNF-α, IL-6 and IL-10 mRNA expression by PBMCs. Moreover, cell viability significantly increased in the presence of high concentrations of colostral carbohydrates. Conclusions: Carbohydrates derived from equine colostrum reduce LPS-induced inflammatory responses of equine PBMCs. Potential relevance: Colostrum and milk-derived carbohydrates are promising candidates for new concepts in preventive and regenerative medicine.
