Abstract
Carbohydrates have long been known to mediate intracellular interactions, whether within one organism or between different organisms. Sialic acids (Sias) are carbohydrates that usually occupy the terminal positions in longer carbohydrate chains, which makes them common recognition targets mediating these interactions. In this review, we summarize the knowledge about animal disease-causing agents such as viruses, bacteria and protozoa (including the malaria parasite Plasmodium falciparum) in which Sias play a role in infection biology. While Sias may promote binding of, e.g., influenza viruses and SV40, they act as decoys for betacoronaviruses. The presence of two common forms of Sias, Neu5Ac and Neu5Gc, is species-specific, and in humans, the enzyme converting Neu5Ac to Neu5Gc (CMAH, CMP-Neu5Ac hydroxylase) is lost, most likely due to adaptation to pathogen regimes; we discuss the research about the influence of malaria on this trait. In addition, we present data suggesting the CMAH gene was probably present in the ancestor of animals, shedding light on its glycobiology. We predict that a better understanding of the role of Sias in disease vectors would lead to more effective clinical interventions.

Nair SS, Chauhan TKS, Kumawat M, Sarkhel R, Apoorva S, Shome A, Athira V, Kumar B, Abhishek, Mahawar M. Deletion of both methionine sulfoxide reductase A and methionine sulfoxide reductase C genes renders Salmonella Typhimurium highly susceptible to hypochlorite stress and poultry macrophages. Mol Biol Rep 2021; 48:3195-3203. [PMID: 33954903 DOI: 10.1007/s11033-021-06381-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 04/24/2021] [Indexed: 10/21/2022]
Abstract
Salmonella Typhimurium survives and replicates inside the oxidative environment of phagocytic cells. Proteins, because of their composition and location, are the foremost targets of host inflammatory response. Among others, Met-residues are highly prone to oxidation. Methionine sulfoxide reductase (Msr), with the help of thioredoxin-thioredoxin reductase, can repair oxidized methionine (Met-SO) residues to Met. There are four methionine sulfoxide reductases localized in the cytosol of S. Typhimurium, MsrA, MsrB, MsrC and BisC. MsrA repairs both protein-bound and free 'S' Met-SO, MsrB repairs protein-bound 'R' Met-SO, MsrC repairs free 'R' Met-SO and BisC repairs free 'S' Met-SO. To assess the role(s) of various Msrs in Salmonella, few studies have been conducted by utilizing ΔmsrA, ΔmsrB, ΔmsrC, ΔmsrAΔmsrB, ΔmsrBΔmsrC and ΔbisC mutant strains of S. Typhimurium. Out of the above-mentioned mutants, ΔmsrA and ΔmsrC were found to play important role in the stress survival of this bacterium; however, the combined roles of these two genes have not been determined. In the current study, we have generated msrAmsrC double gene deletion strain (ΔmsrAΔmsrC) of S. Typhimurium and evaluated the effect of gene deletions on the survival of Salmonella against hypochlorite stress and intramacrophage replication. In in vitro growth curve analysis, ΔmsrAΔmsrC mutant strain showed a longer lag phase during the initial stages of the growth; however, it attained similar growth as the wild type strain of S. Typhimurium after 5 h. The ΔmsrAΔmsrC mutant strain has been highly (~ 3000 folds more) sensitive (p < 0.001) to hypochlorite stress. Further, ΔmsrA and ΔmsrAΔmsrC mutant strains showed more than 8 and 26 folds more susceptibility to poultry macrophages, respectively. Our data suggest that the deletion of both msrA and msrC genes severely affect the oxidative stress survival and intramacrophage proliferation of S. Typhimurium.

Poult Sci 2020; 99:7055-7065. [PMID: 33248622 PMCID: PMC7705041 DOI: 10.1016/j.psj.2020.09.073] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 09/20/2020] [Accepted: 09/24/2020] [Indexed: 12/14/2022] Open
Abstract
Salmonella Typhimurium (S. Typhimurium) infection in broiler chickens threatens public health and livestock production. In this study, we explored the effects of highly nutritious (crude protein 21.8%, metabolizable energy 3.16 Mcal/kg) and lowly nutritious (crude protein 18.1%, metabolizable energy 2.98 Mcal/kg) diets on S. Typhimurium infection by altering the intestinal morphology and environment in broiler chickens. The highly nutritious diet significantly increased the body weight gain and reduced feed conversion ratio on day 1 to 21 (P < 0.01). The highly nutritious diets promoted the intestinal villus height, crypt depth, and their ratio to improve the intestinal epithelial maturation (P < 0.05). Highly nutritious diets significantly increased the expression of claudin-1, occludin, and NF-κB genes in the intestinal epithelium on the days of 14 and 21 (P < 0.05). S. Typhimurium activated the expression of TLR4, MyD88, and NF-κB genes to cause an inflammatory response. The S. Typhimurium can increase the activity of myeloperoxidase, which cause an inflammatory response. The S. Typhimurium significantly reduced the diversity indexes of the ileal microbiota (P < 0.05), increased the abundance of Cyanobacteria which can synthesize toxins. The highly nutritious diet group challenged with S. Typhimurium can increase the abundance of Lactobacillus in the ileum, which lead to improved intestinal health (P < 0.05). It is concluded that increasing the nutritional level of dietary is beneficial to improve the resistance to S. Typhimurium infection by altering the intestinal bacterial community.

Abstract
Macrophages are part of the first line of defense against invading pathogens. In mammals, the in vitro culture of macrophages from blood monocytes or bone marrow cells is well established, including culturing conditions to differentiate them towards M1 or M2-like macrophages. In chicken, monocyte-derived macrophages have been used in several studies, but there is no uniform protocol or actual characterization of these cells. Therefore, to generate proinflammatory M1-like macrophages, in this study blood monocytes were differentiated using GM-CSF for 4 days and characterized based on cell morphology, surface marker expression and cytokine expression response to TLRs stimulation at each (daily) time point. Cell morphology showed that one-day-cultured cells contained a mixture of cell populations, while the homogenous population of cells on day 3 and day 4 were flat and had a 'fried-egg' like shape, similar to human M1 macrophages. In addition, cell surface marker staining showed that 3 and 4- days-cultured cells expressed a high level of MRC1L-B (KUL01) and MHC-II. Furthermore, LPS stimulation of the cultured cells induced gene expression of the proinflammatory cytokines IL-1β, IL-6 and IL-8 after 3 days of culture. Finally, it was shown that day 3 macrophages were able to phagocytose avian pathogenic E. coli (APEC) and respond by nitric oxide production. Overall, our systematic characterization of the monocyte derived cells from blood showed that a 3-days culture was optimal to obtain pro-inflammatory M1 like macrophages, increasing our knowledge about chicken macrophage polarization and providing useful information for studies on chicken macrophage phenotypes.

Abstract
Targeted drug delivery mediated by nanocarriers is a major issue in modern-day medicine. Upon coming in contact with biological fluids (e.g. blood), nanocarriers are rapidly covered by biomolecules (proteins, lipids, etc.) which results in the formation of a surface layer, widely known as the biomolecular corona. The biomolecular corona subsequently confers a certain biological identity to the corona-covered nanocarriers which can be crucial during their subsequent interactions with cells or other biological entities. In contrast to the proteins of the corona, little is known about the impact of the non-protein constituents of the corona, such as sugars. Here, we investigate the role of protein glycosylation of the corona in cellular uptake. We show that deglycosylation of clusterin (CLU) and apolipoprotein AI (Apo AI) significantly changes (increases and decreases, respectively) the cellular uptake of nanocarriers covered with these proteins.
