Abstract
Bovine milk contains bioactive proteins, carbohydrates, and phospholipids with immunomodulatory properties impacting human immunity, potentially contributing to resistance to infections and allergies through diverse mechanisms. One such mechanism is the enhancing of the innate immune response to secondary pathogen-related stimuli, termed innate immune training. Although in vitro studies demonstrate that milk immunoglobulin G (IgG) can train human monocytes, evidence for in vivo immune training is limited. To explore the potential of bovine IgG for inducing innate immune training in vivo, this human study utilized an IgG-rich whey protein concentrate (WPC). Healthy male volunteers were assigned to a high dose WPC, low dose WPC, or placebo group. Blood was collected pre- and post-two weeks of WPC consumption. Peripheral blood mononuclear cells (PBMCs) were isolated and stimulated with TLR ligands, evaluating IL-6 and TNF-α production by monocytes, myeloid DCs, and plasmacytoid DCs. Additionally, RNA was isolated for differential gene expression (DGE) analysis. Results indicated that the two-week WPC intervention did not influence the ex vivo response of studied cells to TLR agonists. Furthermore, PBMC gene expression patterns showed no significant differences between the placebo and high dose WPC groups. The data suggests that oral WPC ingestion did not enhance immune responses in young, healthy male participants.

The Modification of H3K4me3 Enhanced the Expression of CgTLR3 in Hemocytes to Increase CgIL17-1 Production in the Immune Priming of Crassostrea gigas. Int J Mol Sci 2024; 25:1036.

Abstract
Increasing evidence confirms that histone modification plays a critical role in preserving long-term immunological memory. Immune priming is a novel form of immunological memory recently verified in invertebrates. Toll-like receptor (TLR) signaling and cytokines have been reported to be involved in the immune priming of the Pacific oyster Crassostrea gigas. In the present study, the expression of Toll-like receptor 3 (CgTLR3), myeloid differentiation factor 88-2 (CgMyd88-2) and interleukin 17-1 (CgIL17-1) was found to be elevated in the hemocytes of C. gigas at 6 h after the secondary stimulation with Vibrio splendidus, which was significantly higher than that at 6 h after the primary stimulation (p < 0.05). A significant increase in histone H3 lysine 4 trimethylation (H3K4me3) enrichment was detected in the promoter region of the CgTLR3 gene at 7 d after the primary stimulation with inactivated V. splendidus (p < 0.05). After the treatment with a histone methyltransferase inhibitor (5'-methylthioadenosine, MTA), the level of H3K4me3 at the promoter of the CgTLR3 gene decreased significantly at 7 d after the primary stimulation with inactivated V. splendidus (p < 0.05), and the expression of CgTLR3, CgMyD88-2 and CgIL17-1 was significantly repressed at 6 h after the secondary stimulation with V. splendidus (p < 0.05). Conversely, the treatment with monomethyl fumarate (MEF, an inhibitor of histone demethylases) resulted in a significant increase in H3K4me3 enrichment levels at the CgTLR3 promoter at 7 d after the primary stimulation (p < 0.05), and the expression of CgTLR3, CgMyD88-2 and CgIL17-1 was observed to increase significantly at 6 h after the secondary stimulation (p < 0.05). These results suggested that H3K4me3 regulated MyD88-dependent TLR signaling in the hemocytes of C. gigas, which defined the role of histone modifications in invertebrate immune priming.

Abstract
β-glucan, one of the homopolysaccharides composed of D-glucose, exists widely in cereals and microorganisms and possesses various biological activities, including anti-inflammatory, antioxidant, and anti-tumor properties. More recently, there has been mounting proof that β-glucan functions as a physiologically active "biological response modulator (BRM)", promoting dendritic cell maturation, cytokine secretion, and regulating adaptive immune responses-all of which are directly connected with β-glucan-regulated glucan receptors. This review focuses on the sources, structures, immune regulation, and receptor recognition mechanisms of β-glucan.

Nutrients 2022; 14:nu14214452. [PMID: 36364714 PMCID: PMC9654672 DOI: 10.3390/nu14214452] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 10/10/2022] [Accepted: 10/20/2022] [Indexed: 01/24/2023] Open
Abstract
Bovine milk IgG (bIgG) was shown to bind to and neutralize the human respiratory synovial virus (RSV). In animal models, adding bIgG prevented experimental RSV infection and increased the number of activated T cells. This enhanced activation of RSV-specific T cells may be explained by receptor-mediated uptake and antigen presentation after binding of bIgG-RSV immune complexes (ICs) with FcγRs (primarily CD32) on human immune cells. This indirect effect of bIgG ICs on activation of RSV-specific T cells was confirmed previously in human T cell cultures. However, the direct binding of ICs to antigen-presenting cells has not been addressed. As bovine IgG can induce innate immune training, we hypothesized that this effect could be caused more efficiently by ICs. Therefore, we characterized the expression of CD16, CD32, and CD64 on (peripheral blood mononuclear cells (PBMCs), determined the optimal conditions to form ICs of bIgG with the RSV preF protein, and demonstrated the direct binding of these ICs to human CD14+ monocytes. Similarly, bIgG complexed with a murine anti-bIgG mAb also bound efficiently to the monocytes. To evaluate whether the ICs could induce innate immune training more efficiently than bIgG itself, the resulted ICs, as well as bIgG, were used in an in vitro innate immune training model. Training with the ICs containing bIgG and RSV preF protein-but not the bIgG alone-induced significantly higher TNF-α production upon LPS and R848 stimulation. However, the preF protein itself nonsignificantly increased cytokine production as well. This may be explained by its tropism to the insulin-like growth factor receptor 1 (IGFR1), as IGF has been reported to induce innate immune training. Even so, these data suggest a role for IgG-containing ICs in inducing innate immune training after re-exposure to pathogens. However, as ICs of bIgG with a mouse anti-bIgG mAb did not induce this effect, further research is needed to confirm the putative role of bIgG ICs in enhancing innate immune responses in vivo.

Abstract
Respiratory infections place a heavy burden on the health care system, particularly in the winter months. Individuals with a vulnerable immune system, such as very young children and the elderly, and those with an immune deficiency, are at increased risk of contracting a respiratory infection. Most respiratory infections are relatively mild and affect the upper respiratory tract only, but other infections can be more serious. These can lead to pneumonia and be life-threatening in vulnerable groups. Rather than focus entirely on treating the symptoms of infectious disease, optimizing immune responsiveness to the pathogens causing these infections may help steer towards a more favorable outcome. Nutrition may have a role in such prevention through different immune supporting mechanisms. Nutrition contributes to the normal functioning of the immune system, with various nutrients acting as energy sources and building blocks during the immune response. Many micronutrients (vitamins and minerals) act as regulators of molecular responses of immune cells to infection. It is well described that chronic undernutrition as well as specific micronutrient deficiencies impair many aspects of the immune response and make individuals more susceptible to infectious diseases, especially in the respiratory and gastrointestinal tracts. In addition, other dietary components such as proteins, pre-, pro- and synbiotics, and also animal- and plant-derived bioactive components can further support the immune system. Both the innate and adaptive defense systems contribute to active antiviral respiratory tract immunity. The initial response to viral airway infections is through recognition by the innate immune system of viral components leading to activation of adaptive immune cells in the form of cytotoxic T cells, the production of neutralizing antibodies and the induction of memory T and B cell responses. The aim of this review is to describe the effects of a range different dietary components on anti-infective innate as well as adaptive immune responses and to propose mechanisms by which they may interact with the immune system in the respiratory tract.

Abstract
Background and Aim: The transition period is extremely critical for pregnant producing animals. However, there is very limited research on the metabolic and immunological changes in Egyptian water buffalo cows during the transition period. Therefore, this study was conducted to investigate the immunometabolic changes occurring during the transition period in Egyptian water buffalo cows. Materials and Methods: A total of 50 multiparous pregnant Egyptian water buffalo cows were subjected to weekly blood sampling 3 weeks before calving and 3 weeks after calving and on the day of parturition to determine the complete blood count, including red blood cell count, total leukocyte count (TLC), differential leukocyte count, hemoglobin level, and packed cell volume (PCV). Some selected serum biochemical and immunological parameters were analyzed, including serum glucose, beta-hydroxybutyric acid (BHBA), non-esterified fatty acids, triglycerides, high-density lipoprotein, low-density lipoprotein (LDL), very LDL (VLDL), cholesterol, total protein, albumin, globulin, creatinine, blood urea nitrogen (BUN), aspartate aminotransferase, alkaline phosphatase, alanine transaminase, gamma-glutamyl transferase, Haptoglobin, and C-reactive protein and the pro-inflammatory cytokines interleukin β1, interleukin 6 (IL-6), and tumor necrosis factor-alpha. All data were statistically analyzed using the IBM Statistical Package for the Social Sciences statistics software. Results: The neutrophil count showed a statistically significant increase at 2 weeks preparturition. There was also a significant increase in PCV, TLC, neutrophil count, and IL-6 and TNF-a level at the time of parturition and even at 2 weeks post parturition, except PCV that returned to normal levels in the 1st week post parturition. BHBA and BUN levels were increased significantly in the 2nd and 3rd weeks postcalving. Serum creatinine and VLDL levels were decreased significantly at the time of parturition, and VLDL levels showed a significant decrease even till the 3rd week postcalving, whereas creatinine levels gradually returned to the pre-calving levels in the 3rd week postcalving. Other parameters showed no significant changes. Conclusion: The most important immunometabolic changes occur in the first 2 weeks post parturition in Egyptian water buffalo cows, which exhibit a potent, remarkable physiological adaptation achieved by their functional liver, which can help the animal overcome the stressful conditions during the transition period.
