Topic:Antigen
Antigens are substances that can induce an immune response in horses, typically by being recognized as foreign by the immune system. These substances can include proteins, polysaccharides, or lipids, and are often components of pathogens such as bacteria, viruses, or parasites. In horses, antigens are essential for the activation of both the innate and adaptive immune responses, leading to the production of antibodies and the activation of immune cells. The study of antigens in equines encompasses understanding their structure, the mechanisms by which they are recognized by the immune system, and their role in vaccine development. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, characterization, and immunological impact of antigens in equine health and disease.
The quantitative determination of the extent of despeciation of modified equine antitoxin. 1. A method is presented for estimating the relative reactivity with respect to horse serum of antitoxins processed from horse plasma, by observing skin reactions of sensitized rabbits.
2. It is feasible to test 4 preparations, each on 3 rabbits, with standard fiducial limits of from 53% to 188% of the true value.
3. As the sensitizing dose was increased, the relative reactivity of a given test material appeared greater. The function was asymptotic at higher dose levels.
4. The greater the sensitizing dose, the smaller was the variance of the relative reactivity within its replicates.
5. M...

Antiproteins in Horse Sera: III. Antibodies to Rabbit Serum Albumin and Their Reaction with Antigen. 1. Two horses were injected subcutaneously with alum-precipitated rabbit serum albumin. 2. The resulting antibody resembled diphtheria antitoxin and anti-egg albumin in the horse in giving a sharp zone of flocculation with antigen, in being water-soluble, in reactivity toward an anti-antibody rabbit serum, and in its electrophoretic properties. 3. The effect of continued immunization, and of variation in volume and temperature on the reactivity of the antibody are discussed. 4. Intravenous injection of the same antigen into horses did not give rise to detectable amounts of antibody of the same...
