3. 12. Antibody Feedback Regulation : From Epitope Masking to T Helper Cell Activation

   Författare :Andrew Getahun; Birgitta Heyman; Hans-Gustaf Ljunggren; Daniel Conrad; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Immune regulation; B cells; T cells; Antibodies; Fc Receptors; Antigen presentation; Transgenic Knockout Mice; Immunologi; Immunology; Immunologi;

   Sammanfattning : Antibodies have the ability to influence the antibody response against the very antigen they are specific for, in a process called antibody feedback regulation. Depending on the nature of the antigen, the antibody response can be either enhanced or almost completely inhibited. LÄS MER

4. 13. 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.

5. 14. Antibody Feedback Regulation and T Cells

   Författare :Fredrik Carlsson; Birgitta Heyman; Alf Grandien; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fc receptors; B cell; T cell; antigen presentation; complement receptors; complement; IgE; IgG3; CD23; antibody; Immunology; Immunologi;

   Sammanfattning : 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. LÄS MER

7. 15. IgM and Complement in Regulation of Antibody Responses

   Författare :Anna Sörman; Birgitta Heyman; Michael Holers; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; GC responses; feedback regulation; T-cell responses; antigen presentation; complement receptors 1 and 2; Immunologi; Immunology;

   Sammanfattning : Animals deficient in complement components C1q, C4, C3, and CR1/2 have severely impaired antibody responses. C1q is primarily activated by antibody-antigen complexes. Antigen-specific IgM in complex with an antigen is able to enhance the antibody response against that antigen. This is dependent on the ability of IgM to activate complement. LÄS MER
