| Six bovines were infested with 60 first instar larvae of Dermatobia hominis. The animals were bleed weekly, and their antibodies levels to D. hominis L1, L2 and L3 instars measured during the time, following the infestation course. The antisera were submitted to a titration against optimal dilutions of antigen coated wells of microplates, previously sensitized with L1, L2 and L3 preparations, respectively. The ELISA assay was used to test single dilutions of antisera, which results were comparatively analyzed with a control of not infested animals. Antibodies against L1 were detected between the first and 21st day post-infestation (DPI) and, from the 42nd DPI on. Anti-L2 antibodies, could be detected on the 21st DPI and from the 35th DPI until... |

| ABSTRACT: Advances in the fields of glycobiology and immunology have provided many insights into the role of carbohydrate-protein interactions in the immune system. Jacalin of Artocarpus integrifolia (JCA) and structural mannoprotein of Saccharomyces uvarum (MPS) are molecules with immunomodulatory properties. JCA is an IgA human lectin binding molecule that causes the mitogenic stimulation of immune cells, production of cytokines, chemotaxis, and activation of leukocytes. Studies on the immunomodulatory properties of JCA and MPS in mammals and fish suggest that they have an action on antibody production. The aim of this study was to investigate the possible action of JCA and MPS on the production of specific antibodies in laying hens. For this, laying... |
