Cell-bound and circulating IgE antibody to herpes simplex virus

Area of Science:

• Immunology
• Virology
• Allergy

Background:

• Herpes simplex virus (HSV) infections are common.
• The role of immunoglobulin E (IgE) in viral pathogenesis is not fully understood.

Purpose of the Study:

• To investigate the development of IgE-specific antibodies against HSV in a mouse model.
• To explore methods for detecting both cell-bound and circulating IgE antibodies to HSV.

Main Methods:

• Mice were immunized with UV-inactivated HSV or injected with infectious HSV.
• Histamine release from peritoneal mast cells challenged with HSV antigens was measured to detect cell-bound IgE.
• Rat basophilic leukemia (RBL-2H3) cells were sensitized with mouse sera and challenged with antigens to detect circulating IgE.

Main Results:

• Mice immunized or infected with HSV developed IgE-specific antibodies.
• Both cell-bound and circulating IgE antibodies to HSV were successfully detected using the described methods.
• Histamine release correlated with the presence of IgE antibodies.

Conclusions:

• Immunization or infection with HSV can induce an IgE antibody response.
• The methods employed are effective for detecting IgE antibodies against viral antigens.
• IgE antibodies may play a role in the pathological processes of viral infections like HSV.
