Independent appearance of anti-thymocyte and anti-RNA antibodies in NZB/NZW F1 mice

R GoldblumN Talal


NZB and NZB/NZW (B/W) mice were studied for natural thymocytoxic autoantibody(NTA) and antibody to reovirus RNA by cytotoxicity and radioimmunoassay respectively.NZB mice developed NTA by 2-3 months of age. RNA antibodies appeared later if atall. NTA and anti-RNA were present in B/W mice starting at 4-5 months and increased in frequency with age. Either activity could appear first and could be present without the other. Thus, all four possible patterns of autoantibody occurrence were found. NTA and anti-RNA in 12-month B/W sera were separable by sucrose density gradient ultracentrifugation; NTA is a 19S IgM antibody whereas anti-RNA is 7S.

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.
