Inflammation is a mechanism that provides protection against injury, trauma, or infection caused by damaged cells, irritants, or pathogens. This process removes harmful agents and damaged tissue components. Nevertheless, chronic low-grade inflammation is often associated with various pathologies. Diet could be a promising way of action. Indeed, bioactive peptides derived from the hydrolysis of dietary proteins could modulate key inflammatory factors and consequently delay the onset of these chronic diseases. Furthermore, lactic acid bacteria, components of fermented milk products, exhibit anti-inflammatory properties both in vitro and in vivo studies. Among them, Streptococcus thermophilus (ST) is regularly consumed by a significant part of the population. Studies have shown that some strains of ST display anti inflammatory activity in vitro with an unknown mechanism of action. In this work, it was hypothesized that peptides released after hydrolysis by digestive proteases of the surface or intracellular proteins of this bacterium could be involved at least partially in this activity. Firstly, hydrolysates were obtained by shaving surface proteins with trypsin or pepsin followed or not by trypsinolysis. The tandem mass spectrometry analysis indicated that the majority of the identified peptides belonged to the surface proteins of this bacterium. Secondly, the anti inflammatory activity of the hydrolysates was evaluated in two inflamed cell models. The hydrolysate obtained after tryptic shaving and trypsinolysis of surface proteins of ST LMD 9 significantly decreased the secretion of the pro-inflammatory cytokine IL 8 in lipopolysaccharide (LPS) stimulated HT 29 cells. The same hydrolysate also reduced production of IL 8 and of the pro-inflammatory cytokine IL 1β as well as protein expression levels of Pro IL 1β and COX 2 in LPS-stimulated THP 1 macrophages. It was proposed that the surface protease PrtS could be a source of active peptides during gastrointestinal digestion. To verify this hypothesis, hydrolysates were prepared by shaving with pepsin followed or not by trypsinolysis of the surface proteins of two phenotypically distinct strains of ST: LMD 9 (PrtS+) and CNRZ 21N (PrtS-). Modulation of pro-inflammatory mediators IL 8, IL 1β, Pro IL 1β and COX 2 was assessed in LPS-stimulated THP 1 macrophages and IL 8 in LPS stimulated HT 29 cells. The hydrolysates from the two strains showed an anti inflammatory action but modulation of all these inflammatory mediators was strain, hydrolysate, and concentration dependent. Interestingly, the strain lacking PrtS also showed anti-inflammatory activity. Therefore, peptides released from surface proteins of ST strains by proteases of the gastrointestinal tract during digestion of a product containing this bacterium could exert anti-inflammatory effects and thus could reduce the risk of inflammation related chronic diseases. Finally, the intracellular proteins of the LMD 9 and CNRZ 21N strains were recovered by sonication and hydrolysed with Corolase PP, a mixture of pancreatic proteases. Hydrolysates generated from a fraction of these proteins of both strains demonstrated anti inflammatory action by modulating some of the pro-inflammatory mediators in LPS stimulated THP 1 macrophages. To our knowledge, this is the first study demonstrating the anti inflammatory activity of peptides derived from surface proteins and a fraction of the intracellular proteins of ST strains. These paraprobiotics or postbiotics, likely to be released in the digestive tract of the consumer, could participate in the overall anti inflammatory effect of S. thermophilus which had been demonstrated with certain strains. They could display beneficial effects on human health and therefore could be a promising bioactive ingredient for the development of novel functional foods for the prevention of low grade inflammation

Milk fat globules are composed of a triglyceride core and a natural biological membrane, milk fat globule membrane (MFGM). Proteins account for 70% of MFGM. Certain of those proteins are important for the secretion and structural stability of milk fat globule. However, composition of MFGM is restructured after homogenization, and the newly formed membrane mainly consists of caseins and whey proteins. The aim of this study was to examine the lipolysis of milk fat in raw milk, HTST milk, and homogenized HTST milk by pancreatic lipase during in vitro intestinal and gastrointestinal digestion, with and without the presence of trypsin. The results of in vitro intestinal digestion indicated that whether presence trypsin or not, homogenized HTST milk showed higher level of free fatty acids release than raw milk and HTST milk. Releasable free fatty acids were not significantly different among raw milk, HTST milk, and homogenized HTST milk on gastrointestinal digestion. During in vitro gastrointestinal digestion, the hydrolysis rate of milk fat in raw milk, HTST milk, and homogenized HTST milk increased on early stage of lipolysis after pepsin digestion. However, trypsin treatment could not further increase milk fat hydrolysis rate on gastrointestinal digestion early stage of lipolysis. Homogenized HTST milk and HTST milk fat hydrolysis rate on early stage of trypsin presence in vitro intestinal digestion were higher than trypsin absence in vitro intestinal digestion. In conclusion, gastrointestinal proteases play a coordinative role to increase fresh milk fat hydrolysis on early stage of in vitro digestion.
