1. Antibody Feedback Regulation and T Cells
Abstract : Antibodies, passively administered or actively produced, regulate immune responses to the antigen they recognize. This phenomenon is called antibody-mediated feedback regulation. Feedback regulation can be positive or negative, resulting in >1000-fold enhancement or >99% suppression of the specific antibody response. READ MORE

2. Early Immunostimulatory Effects of IgE- and IgG Antibodies
Abstract : Antibodies have the ability to influence their own production in a process called antibody feedback regulation. Depending on the type of antigen and the subclass of the antibody, the outcome of feedback regulation can be complete suppression or several hundred-fold enhancement of the antibody response.

3. Modulation of B cell access to antigen by passively administered antibodies : an explanation for antibody feedback regulation?
Abstract : Antibody responses can be up- or down-regulated by passive administration of specific antibody together with antigen. Depending on the structure of the antigen and the antibody isotype, responses can be completely suppressed or enhanced up to a 1000-fold of what is seen in animals immunized with antigen alone.

4. Why Is It So Hard to Kill a Mast Cell?A Study of Mast Cell Activation and Survival
Abstract : Mast cells have a long life in tissues, where they are involved in inflammatory and hypersensitivity reactions. Activation through cross-linking of the high-affinity IgE-receptor (FcεRI) is a primary stimulus capable of degranulating mast cells, contributing to symptoms of allergy. READ MORE

5. Mast Cell Progenitor Trafficking in Allergic Airway Inflammation
Abstract : Mast cell progenitors originate from the bone marrow and migrate to the lungs via the blood. During maturation, these cells acquire granules that contain a potent array of bronchoconstrictive mediators. READ MORE
