Objective(s):Recent evidence have proposed that Tretinoin produced in the gut preferentially promote differentiation of FoxP3+Treg cells but inhibits Th17 lymphocytes, and this may be the main immunomdulatory mechanism of Tretinoin  in vivo. This study was done to investigate the effects of Tretinoin in outbred white mice after challenge with sheep red blood cells (SRBC). Materials and Methods:...

the objective of this study was to evaluate the effects of cottonseed meal (csm) treated with sodium bentonite (sb) on certain blood components and immune response of laying hens. a 3 × 3 factorial arrangement with 3 levels of sb (0, 10, and 20 g/kg of diet) and 3 levels of csm (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. nine mash diets were fed to ...

We have recently demonstrated that immunization with hepatitis C virus-like particles (HCV-LPs) generated in insect cells can elicit both humoral and cellular immune responses in BALB/c mice. Here, we evaluate the immunogenicity of HCV-LPs in HLA2.1 transgenic (AAD) mice in comparison to DNA immunization. HCV-LP immunization elicited a significantly stronger humoral immune response than DNA imm...

Especially complicated, renal lithiasis contributes to the general inflammatory syndrome development that interferes with nonspecific, humoral and cellular immune system. The surgical treatment of nephrolithiasis is closely related to drug therapy of urinary infection, one of the reasons being the reduction of the immune status. The work is performed by evaluating the immunological status preop...

Chickens which were given cyclophosphamide during the first three to five days of life showed a marked depression in their humoral antibody response to sheep erythrocytes and Bmcel/a antigen. Thei r ability to deve...

Immunization with Pseudomonas lipopolysaccharide induced both cellular and humoral immunity in rabbits, particularly in the respiratory tract after intranasal immunization. Either parenteral (i.m.) or intranasal immunization elicited an IgG antibody response in respiratory secretions, but only intranasal immunization produced secretory IgA antibody. Immunization by both routes stimulated serum ...

Tumor-specific immunotherapy holds the promise of eradicating malignant tumors with exquisite precision without additional toxicity to standard treatments. Cancer immunotherapy has conventionally relied on cell-mediated immunity while successful infectious disease vaccines have been shown to induce humoral immunity. Efficacious cancer immunotherapeutics likely require both cellular and humoral ...

Congenital rubella syndrome still occurs throughout the world despite an effective vaccine being used in developed countries. Heat and light lability, as well as contraindications in immunocompromised persons, limit the use of the vaccine. An improved, more durable and less reactive rubella vaccine such as a peptide or subunit vaccine would address these unmet needs. We have sought to identify ...

In a recent study, we reported that a recombinant protein from fusion expression of flagellin to porcine circovirus type 2 (PCV2) Cap induced robust humoral and cell-mediated immunity that afforded full protection for PCV2 infection using BALB/c mice. Here, we further evaluated the immunogenicity and protection of the recombinant protein using specific pathogen free (SPF) pigs. Twenty-five 3-we...
