Abstract
Allergy by cow's milk proteins is among the major food allergies and could be reduced by the partial hydrolysis of these proteins by proteases, without significantly affecting its physicochemical properties. In addition, the peptides generated through enzymatic hydrolysis of the cow's milk can present prebiotic and bioactive properties. In this work, the cow's milk proteins were submitted to a controlled hydrolysis by Novo-Pro D® and the influence of the degree of hydrolysis (DH) on peptide size distribution was evaluated, as well as the prebiotic and antimicrobial properties of milk hydrolysates. It was shown that for DH-10%, all the peptides have sizes lower than 12 kDa which is the size of the most allergenic proteins, without apparent changes in the milk, as long as heating of the hydrolysate is avoided. The protein hydrolysis promoted a great improvement in the milk functional properties. In addition, the obtained milk peptides presented great prebiotic activities, as indicated by the significant improvement of the growth of prebiotic L. acidophilus and L. reuteri and by the production of bacteriocins indicated by the inhibition halos in the growth of a pathogenic microorganism.

Abstract
Infections of microbial and non-microbial origins have been associated with significant immunological manifestations, thereby underscoring the need for a thorough understanding and investigation of novel immunomodulatory and antioxidant molecules that could prevent these incidences. To this end, we herein aim to identify fermented milk peptides with antioxidant and immunomodulatory properties that could be exploited for specific future applications. Our computational prediction models indicate that these peptides are non-toxic and possess considerable hydrophobicity (19.82-38.96 %) and functionality. Further analyses reveal that two of the four peptides, i.e., Pep 1 (AGWNIPM) and Pep 4 (YLGYLEQLLR), possess higher in-vitro antioxidant activity. The immunomodulatory potential of these two peptides (Pep 1 and Pep 4) is further demonstrated by using a combination of molecular simulation trajectory and ex-vivo approaches. Both peptides demonstrate ability to control the production of pro- inflammatory (TNF-α, IL-1, and IL-6) and anti-inflammatory (IL-10) cytokines as well as nitric oxide release in LPS-stimulated murine peritoneal macrophages. Similarly, peptide interferences also lead to significant (P < 0.05) improvement in macrophage phagocytic capacity. Taken together, these findings highlight the antioxidant and immunomodulatory properties of fermented milk peptides (Pep 1 and Pep 4) within the cellular environment and should facilitate prospective studies exploring such bioactive peptides and related functional molecules mediating the benefits of fermented milk products on human health.

Abstract
The COVID-19, an acute respiratory syndrome caused by SARS-CoV2 is a major catastrophic event of the twenty first century. Relentless efforts for the development of effective pharmaco-therapeutics are in progress but the respite is the development of effective vaccines. However, monotherapy might not always exhibit complete efficacy and may culminate in the rapid evolution of drug-resistant viral strains. Hence, simultaneous modulation of multiple druggable targets not only enhances therapeutic efficacy but also quell the prospects of mutant viruses. Currently, milk peptides have bloomed beyond just being a quintessential part of nutrition to prominent therapeutic implications in human health and diseases. Hence, we have focused on colostrum/milk peptides as they have already been acknowledged for their high potency, target specificity with significantly low or no side effects and bio-toleration. The results presented provide a conceptual strategy for the rational designing of prospective multitargeted peptide inhibitors for SARS-CoV2.

Abstract
Infant Milk Formula (IMF) is designed as a breastmilk substitute to satisfy the nutritional requirements during the first months of life. This study investigates the effects of two IMF processing technologies on cow milk protein digestion using an infant static in vitro gastrointestinal model. The degree of protein hydrolysis at the end of the gastric phase was 3.7-fold higher for IMF produced by high temperature (IMF-HT), compared to IMF produced by cascade membrane filtration (IMF-CMF), as assessed by free N-terminal group analysis. The processing type also influenced the panel of bioavailable peptides detected in basolateral compartments of Caco-2 monolayers exposed to gastrointestinal digested IMFs. In addition, IMF-CMF significantly increased tight junction protein, claudin 1, whilst IMF-HT significantly reduced tight junction integrity. In conclusion, producing IMF by CMF may preserve intestinal barrier integrity and can deliver its own unique inventory of bioavailable peptides with potential bioactivity.

Abstract
Human milk is a dynamic protein-protease system that delivers bioactive peptides to infants. The pH of milk changes from the mother's mammary gland to the infant's digestive tract. Although the release of human milk peptides has been studied during in vivo or in vitro digestion, these models did not explicitly vary nor observe the effect of pH. The objective of this research was to determine the effect of pH on the proteolysis of human milk. Using high-resolution accurate-mass Orbitrap mass spectrometry, profiles of endogenous human milk peptides before and after incubation at various pH levels have been mapped. Over 5000 peptides were identified. Comparative analyses classified 74 peptides that were consistently found independent of pH alterations, and 8 peptides that were released only at pH 4 or 5 (typical infant gastric pH). Results documented that the proteolysis of milk proteins, particularly β-casein, polymeric immunoglobulin receptor, and α-lactalbumin, is pH-dependent.
