Project description:The proteins of the milk fat globule membrane (MFGM) have a number of functions, such as the regulation of milk fat secretion and metabolism, the uptake and transportation of fatty acids in the intestine and potential protection from bacterial or viral infection. While the proteome of the MFGM in bovine milk has been extensively characterised, our knowledge of these proteins in buffalo milk is limited. In this study, a proteomic approach was used to characterise the proteome of the buffalo MFGM. Multiple extraction techniques were employed to increase the coverage of proteins identified, while label free relative quantitative liquid chromatography tandem mass spectrometry was used for comparison between the buffalo and bovine MFGM proteome. A total of 220 buffalo MFGM proteins and 234 bovine MFGM proteins were identified after being filtered from the initial dataset of 757 and 680 proteins respectively. Significantly greater amounts of xanthine oxidoreductase, platelet glycoprotein 4, heat shock cognate and calcineurin B homologous protein were identified per mass of buffalo MFGM protein extracted. The higher expression of xanthine oxidase in the MFGM of buffalo milk was confirmed by Western blot analysis and a heterogeneous distribution of this protein observed in situ on the surface of the MFGM. The high concentration of fat in buffalo milk, together with the differences in the MFGM proteome indicate differences in the nutritional profile, biological function, and potential ease of processing of buffalo and bovine milk products.

Project description:The detection of dairy processing is pivotal to our understanding of ancient subsistence strategies. This culinary process is linked to key arguments surrounding the evolution of lactase persistence in prehistory. Despite extensive evidence indicating the presence of dairy products in ceramics in the European Neolithic, questions remain about the nature and extent of milk (and lactose) processing and consumption. In order to investigate past patterns of dairy processing, here we analyse ancient proteins identified from Late Neolithic Funnel Beaker ceramics, scrutinising the principle that curd and whey proteins partition during the production of dairy foods from milk. Our results indicate the presence of casein-rich dairy products in these vessels suggesting the creation of curd-enriched products from raw milk. Moreover, this analysis reveals the use of multiple species for their dairy products in the Late Neolithic Funnel Beaker culture, adding to a growing body of evidence that multiple taxa were exploited for dairying in the Neolithic. Alongside palaeoproteomic analysis we also apply lipid residue analysis, with discrepancies in these two approaches suggesting that effects from isotope mixing may be underestimating the frequency of milk use in prehistoric pottery, highlighting the utility of a multi-stranded approach.

Project description:The study reports a differential proteomic analysis of the Mediterranean buffalo milk to evaluate the changes induced by Staphylococcus spp. during a subclinical intramammary infection (IMI). A number of 12 quarter milk samples, 6 of which with somatic cell count (SCC) < 50,000 cells/mL and culture-negative, and the other 6 with SCC ˃ 3,000,000 cells/mL and culture-positive to Staphylococcus aureus (SAU, n=3), SAU, or non-aureus staphylococci (NAS, n=3) was selected. Samples were analyzed using a shotgun proteomics approach, based on filter-aided sample preparation (FASP) followed by LC-MS/MS and label-free analysis. Here, the largest buffalo milk protein dataset described so far was reported. Moreover, the results demonstrated that staphylococcal IMI mostly affected proteins involved in structural functions and in innate immune defense, with changes in their abundance that were generally more intense in SAU than in NAS samples. Further, an increase in the abundance of different cathelicidins was observed, as already reported for other animals with mastitis disease (1,2).

In conclusion, our results provide the first in depth characterization of buffalo milk proteins, describe the changes induced by SAU and NAS subclinical intramammary infection and suggest indications to reveal subclinical staphylococcal mastitis in buffalo by the milk proteome investigation.
