1. 6. Modulation of B cell access to antigen by passively administered antibodies : an explanation for antibody feedback regulation?

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; IgG3; IgE; suppression; enhancement; epitope masking; antigen transport; antigen presentation; follicular B cells; marginal zone B cells; Immunologi; Immunology;

   Sammanfattning : 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.

3. 7. Early Immunostimulatory Effects of IgE- and IgG Antibodies

   Författare :Fredrik Hjelm; Birgitta Heyman; Sandra Kleinau; Robert Harris; Uppsala universitet; []
   Nyckelord :Immunology; Antibodies; Fc receptors; Antigen presentation; B cells; T cells; Immunologi;

   Sammanfattning : 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. LÄS MER
