    Abstract Background: Mast cell (MC)-derived mediators induce vasodilatation and fluid extravasation, leading to cardiovascular failure in severe anaphylaxis. We have previously revealed a synergistic interaction between the cytokine IL-4 and the MC-derived mediator histamine in modulating vascular endothelial (VE) dysfunction and severe anaphylaxis. The mechanism by which IL-4 exacerbates histamine-induced VE dysfunction and severe anaphylaxis are unknown.
    Objective: To identify the IL-4-induced molecular processes regulating the amplification of histamine-induced VE barrier dysfunction and the severity of IgE-mediated anaphylaxic reactions.
    Methods: RNAseq, Western blot, Ca
    Results: IL-4 enhancement of histamine-induced VE barrier dysfunction was associated with increased VE-Cadherin degradation, intracellular calcium flux, phospho-Src levels and required transcription and de novo protein synthesis. RNAseq analyses of IL-4 stimulated VE cells identified dysregulation of genes involved in cell proliferation, cell development, and cell growth and transcription factor motif analyses revealed a significant enrichment of differential expressed genes (DEGs) with putative STAT3 and STAT6 motif. IL-4 stimulation in EA.hy926 cells induced both STAT3
    Conclusions: These studies unveil a novel role of the IL-4/ STAT6 signaling axis in the priming of VE cells predisposing to exacerbation of histamine-induced anaphylaxis.

    Abstract Background: Supplementation of sulfur (S) and folic acid (FA) are known to spare the dietary requirement of methionine (Met) in chicken. An experiment was conducted to determine the effects of feeding graded concentrations of FA (0, 2, 4, 6, 8 mg kg
    Results: Broilers fed the NC diet had lower body weight gain (BWG), high feed conversion ratio, lower ready-to-cook yield, higher lipid peroxidation and reduced concentrations of protein and albumin in serum. BWG improved with FA at day 21 and showed a trend of improvement at day 42. Similarly, BWG improved with S supplementation at day 42. The FA and S interaction indicated a significant reduction in lipid peroxidation with S supplementation at the majority of FA levels. Serum protein fractions increased with increased dietary FA content and increased further with S supplementation.
    Conclusion: Based on the results, it is concluded that the combination of FA (4 mg kg

    Abstract The study was designed with the objective of expression analysis of pro-apoptotic BAX and anti-apoptotic BCL-2 genes on lactation performance in Bos indicus and HF crossbred cows during early lactation. BAX/BCL-2 mRNA expression ratio in HF crossbreds showed a steady increase from 30th day to 90th day, but in Deoni cows the ratio exhibited a different pattern, which increased from day 30 to day 60, decreased on day 75, and then increased on day 90. BAX/BCL-2 expression ratio in Deoni and HF crossbreds were lowest on day 30 and highest on day 90. On contrary, the milk yield was highest on day 30 and lowest on day 90 suggesting BCL-2 gene favors milk production and BAX gene oppose milk production. In comparison to HF crossbreds, Deoni cows exhibited highest BAX/BCL-2 ratio at the end of early lactation, indicating Bos indicus cows were more sensitive to apoptosis than HF crossbreds. Comparison of daily milk yield with BAX/BCL-2 mRNA expression ratio revealed significant negative correlation with a correlation coefficient of −0.98 (P < 0.01) and −0.95 (P < 0.05) in Deoni and HF crossbred cows, respectively. Our study provides new insights into understanding the genetic control of mammary apoptosis between Bos indicus and HF crossbreds.

    Abstract Background and aims: The long-term effect of immune tolerance has not been explored so far in atherosclerosis. In the present study, we assessed the effect of mucosal tolerance to a multi antigenic construct expressing three peptides from ApoB, HSP60, and outer membrane protein from Chlamydia pneumonia (AHC) for 30 weeks at every 6-week interval to understand the kinetics of immune modulation in disease progression. The safety profile of the molecule was also evaluated in mice.
    Methods: Apob
    Results: Treated animals showed an efficient reduction in plaque growth and lipid accumulation at 6 weeks (49%, p < 0.01) and 12 weeks (42.3%, p < 0.01) which decreased to 29% (p = 0.0001) at 18 weeks and at later time points. Macrophage accumulation was significantly lower at all time points (53% at 12 weeks to 27% at 30 weeks). Regulatory T cells increased in the spleen following treatment until 12 weeks (week 0 (2.57 ± 0.18 vs. 6.36 ± 0.03, p = 0.02), week 6 (4.52 ± 0.2 vs. 8.87 ± 0.32, p = 0.02), and week 12 (8.74 ± 0.37 vs. 15.4 ± 0.27, p = 0.02)) but showed a decline later. A similar trend was observed with tolerogenic dendritic cells. We observed an increase in antibody levels to low-density lipoprotein and oxidized LDL at later stages. AHC molecule was found to be safe in acute and repeated dose toxicity studies.
    Conclusions: Our results suggest that immune tolerance to AHC protein by oral administration is able to provide efficient atheroprotection up to 18 weeks and moderately at later stages. Apart from immune regulatory cells, protective antibodies may also have a role in controlling atherosclerosis.

    Abstract Objective An experiment was conducted to determine the effects of supplementing graded concentrations of inorganic sulphur (S) without and with folic acid (FA) in maize-soybean meal diets on performance, slaughter and anti-oxidant variables, immune responses and serum protein fractions in broiler chicken. Methods Inorganic S was supplemented at 0.05%, 0.10%, 0.15%, and 0.20% alone or in combination with FA (4 mg/kg) in basal diet (BD) containing no supplemental methionine (Met) and FA. A control group was fed with the recommended concentration of Met. Each diet was offered to 10 pens of 5 male broiler chicks (Cobb 400) and fed ad libitum from day 1 to 42. Results The broilers fed the BD had lower body weight gain (BWG), feed efficiency (FE), higher lipid peroxidation (LP), lower activity of glutathione peroxidase (GSHPx), lower lymphocyte proliferation ratio (LPR), and reduced concentrations of total protein, albumin, and globulin in serum. Supplementation of FA and S to the BD improved the BWG (all concentrations of S) and FE (0.20% S) similar to the control group. Similarly, the combination of S and FA significantly improved the concentrations of total protein, albumin, and globulin in serum, reduced the LP and increased the activity of GSHPx and LPR. However, responses in the above parameters were related to the concentration of S in the diet. The slaughter variables and antibody titres against the Newcastle disease were not affected with the treatments. Conclusion Based on the results, it is concluded that the combination of S (0.2%) and FA (4 mg/kg) improved the BWG and FE, similarly supplementation of these nutrients improved the concentration of protein fractions and reduced the stress (reduced LP and improved GSHPx) variables in serum and improved the cell mediated immune response (LPR) in broilers fed sub-optimal concentrations of Met in diet.

    Abstract BACKGROUND: Supplementation of sulfur (S) and folic acid (FA) are known to spare the dietary requirement of methionine (Met) in chicken. An experiment was conducted to determine the effects of feeding graded concentrations of FA (0, 2, 4, 6, 8 mg kg⁻¹) and two concentrations of S (0 and 2 g kg⁻¹) in 5 × 2 factorial design. Diet without FA and S was considered as negative control (NC). Another diet with the recommended concentration of Met was considered as the positive control (PC). Each diet was offered ad libitum from day 1 to 42 to 10 pens of 20 male chicks each. RESULTS: Broilers fed the NC diet had lower body weight gain (BWG), high feed conversion ratio, lower ready‐to‐cook yield, higher lipid peroxidation and reduced concentrations of protein and albumin in serum. BWG improved with FA at day 21 and showed a trend of improvement at day 42. Similarly, BWG improved with S supplementation at day 42. The FA and S interaction indicated a significant reduction in lipid peroxidation with S supplementation at the majority of FA levels. Serum protein fractions increased with increased dietary FA content and increased further with S supplementation. CONCLUSION: Based on the results, it is concluded that the combination of FA (4 mg kg⁻¹) and S (2 g kg⁻¹) improved BWG. Similarly, the feed efficiency with 6 mg FA alone or with S was similar to the PC group. The improvement was probably due to the increase in protein accretion and reduction in lipid peroxidation with FA and S supplementation. © 2022 Society of Chemical Industry.
