Demonstration of specific antibodies in the central nervous system of horses naturally infected with Borna disease virus.
Abstract: From 18 horses with clinical symptoms of an affection of the central nervous system and with histopathologic alterations in the brain, four were demonstrated to have Bornavirus-specific antibodies. The antibodies are monospecific, recognizing identical antigens from infected brains of different animal species as well as from persistently infected tissue culture cells. Discrete immunoglobulin species (oligoclonal IgG) can be demonstrated in concentrated horse cerebrospinal fluid; they carry Bornavirus antibody specificity. Their presence, together with the higher antibody titers in the cerebrospinal fluid as compared to those in the serum, indicate that in these natural Bornavirus infections local antibody production occurred in the central nervous system.

This research considers horses showing signs of a nervous system affection and brain alterations, discovering that four of the 18 horses studied contained specific antibodies for Borna disease virus. The findings imply that these natural Borna virus infections lead to the local production of these antibodies within the central nervous system.
Objectives and Methodology
- The goal of the researchers was to identify the presence of specific antibodies geared toward the Borna disease virus in the central nervous system of horses displaying related symptoms.
- They conducted their study on 18 horses that exhibited signs of a central nervous system disorder and histopathologic changes in the brain.
- These horses were screened for Bornavirus-specific antibodies, which could provide clear indications of a Borna disease virus infection.
Findings
- Out of the 18 horses investigated, four were found to possess Bornavirus-specific antibodies, suggesting they once fought off the Borna disease virus.
- These antibodies displayed monospecificity, indicating they recognized the same antigens from infected brains across different animal species and persistently infected tissue culture cells.
- Discrete immunoglobulin species (oligoclonal IgG) were identified in concentrated horse cerebrospinal fluid, and these demonstrated Bornavirus antibody specificity.
- The higher detection rate of the antibodies in the horses’ cerebrospinal fluid compared to the serum (blood) suggests local antibody production in the central nervous system.
Implications
- The presence of specific antibodies against the Borna virus in the animal’s cerebrospinal fluid implies that the body is mounting a direct immune response within the central nervous system itself to fight the infection.
- This research might offer valuable insight into the pathophysiology of Borna disease and how the immune system naturally combats the virus.
