Background: As an important nutrient, soybean protein-derived peptides (SPP) affect the immune function of animals. Objective: This study describes the effects of nutrient supplementation with SPP on the negative nitrogen balance in the burn injury-induced inflammatory response of aged rats. Design: Soybean protein isolate (SPI) was hydrolyzed to obtain SPP. A negative nitrogen-balance aged rat model and a major full-thickness 30% total body surface area (TBSA) burn-injury rat model were utilized. Results: The results show that SPP can increase the speed and ability of inflammatory stress by adjusting white blood cell counts. Soybean protein-derived peptides significantly increased serum immunoglobulin M (IgM), immunoglobulin G (IgG) and immunoglobulin A (IgA) levels; significantly decreased serum interleukin-1 beta (IL-β), tumor necrosis factor-alpha (TNF-α) and regulated upon activation normal T-cell expressed and secreted (RANTES) levels. These results give conclusive evidence that SPP has a significantly positive effect in improving the immune function on the condition of negative nitrogen balance with burn-injury, and reducing excessive inflammation. Conclusions: Nutrient supplementation of SPP can, therefore, be used as an adjuvant treatment to inhibit the development and severity of inflammatory reactions caused by burns, providing a novel therapy for the treatment and positive prognosis of burn patients.

Antarctic krill (Euphausia superba) protein hydrolysates were produced by simulated gastrointestinal digestion (KPHSD) and alkaline proteinase hydrolysis (KPHAP), respectively. The effects of the hydrolysates on cholecystokinin (CCK) secretion and cAMP response element-binding protein (CREB) activation were tested in murine enteroendocrine cell line STC-1. Meanwhile, the signaling mechanism by which the hydrolysates induce CCK secretion was investigated by using inhibitors of signaling proteins. Results indicated that KPHSD and KPHAP both could significantly stimulate CCK secretion and CREB activation. The stimulating effects on CCK release showed a positive correlation with the relative content of peptides with molecular weight ranging from 1,000 to 3,000 Da, indicating this component may mainly account for the ability. The inhibitors on calcium-sensing receptor, PKA, Ca 21 /CaMKII, P 38 -MAPK, and an intracellular calcium chelator all inhibited krill protein hydrolysates-induced CCK secretion and CREB activation, indicating the involvement of the Ca 21 /CaM/CaMK, cAMP/PKA and MAPK pathways in the stimulation of CCK secretion. PRACTICAL APPLICATIONSAlthough Antarctic krill (Euphausia superba) has a large biomass and high-quality protein, its consumption by mankind, especially for its protein, is limited. In recent years, krill protein hydrolysates (KPHs) have attracted increasing attention due to their various health benefits. KPH is usually produced by using a proteolysis and centrifugation process, and the protein from muscle and internal tissue is reserved, but the cuticle is removed. The process can produce low-fluoride krill proteins (peptides) because the fluoride in krill is mainly located in the cuticle. The present study showed that KPHs produced by simulated gastrointestinal digestion and by alkaline proteinase hydrolysis were able to highly stimulate CCK secretion in intestinal endocrine STC-1 cells, indicating KPHs have potential application prospect as functional food ingredients for food intake-inhibitory effects.
