A B Cell Epitope Peptide Derived from the Major Grass Pollen Allergen Phl p 1 Boosts Allergen-Specific Secondary Antibody Responses without Allergen-Specific T Cell Help
More than 40% of allergic patients suffer from grass pollen allergy. Phl p 1, the major timothy grass pollen allergen, belongs to the cross-reactive group 1 grass pollen allergens that are thought to initiate allergic sensitization to grass pollen. Repeated allergen encounter boosts allergen-specific IgE production and enhances clinical sensitivity in patients. To investigate immunological mech...

The induction of humoral immune responses to a variety of antigens requires the cooperative participation of both thymus-derived (T) and bone marrowderived (B) lymphocytes. The former cells exert very definite regulatory influences on the responses of IgM and IgG B lymphocyte precursors of antibody-forming cells with respect to triggering and differentiative events after exposure to antigen (re...
متن کاملRecent Progress in Allergen Immunotherapy
The efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. Immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...
متن کاملImpaired antibody responses in H-2Ab mice.
In murine in vivo systems, Ags administered in physiologic solutions together with specific IgE induce a significantly higher Ab response than Ags administered alone. In vitro, IgE in complex with Ag enhances B cell-mediated presentation of the Ag to T cells. Both phenomena require an intact low affinity receptor for IgE (Fc epsilon RII/CD23), suggesting that the effect on in vivo Ab responses ...
متن کاملPoor association of allergen‐specific antibody, T‐ and B‐cell responses revealed with recombinant allergens and a CFSE dilution‐based assay
BACKGROUND The adaptive immunity underlying allergy comprises two components, the allergen-specific antibody (i.e. IgE, IgG) and the T-cell response. These two components are responsible for different disease manifestations and can be targeted by different therapeutic approaches. Here, we investigated the association of allergen-specific antibody and T- as well as B-cell responses in pollen-all...
