Characterization of a homogeneous paraprotein from a horse with spontaneous multiple myeloma syndrome

Veterinary Immunology and Immunopathology
R K SeideJ M Kehoe


A novel myeloma paraprotein has been isolated from a horse with a lymphoid tumor. The protein was a euglobulin and consequently was readily isolated from serum in pure form and high yield by simple dilution in distilled water. The purified intact protein had a molecular weight of 150,000 and was composed of heavy and light chains, both of which had blocked amino-termini and were thus not susceptible to amino-terminal sequence analysis. The amino acid compositions of these respective chains corresponded to those of comparable chains from immunoglobulins of other species. Peptide maps of paraprotein light chains prepared by high pressure liquid chromatography corresponded in part to those of normal pooled equine light chains. The identification of this paraprotein as an equine AI (aggregating immunoglobulin) protein was confirmed by serological analysis using a specific antiserum. The relationship of this particular protein to other members of the immunoglobulin family was further demonstrated by the production of an anti-idiotypic antiserum individually specific for this molecule.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
