Abstract: Provided herein are methods for diagnosing the probability of extended duration of severe COVID19 symptoms in a subject infected with a SARS-CoV2 virus or suspected of being infected with the SARS-CoV2 virus, the method including (a) providing a biological sample from the subject; and (b) detecting the presence of an anti-ACE2 IgM antibody in the biological sample, thereby diagnosing the probability of extended duration of severe COVID19 symptoms in the subject.

Abstract: The present inventors identified a subpopulation of genes induced by type I and type II IFNs in a human submandibular gland (HSG) epithelial cell line. Unexpectedly, it was found that the majority of genes that are highly up-regulated by IFN-? are also highly induced by IFN-?. In contrast, there was a substantial group of genes that are highly induced by IFN-? only. In target tissues, this identified subpopulation of genes and probes allow different IFN patterns to be discerned, enabling more precise molecular classification of patient subpopulations. The identified gene probes are useful for selecting and monitoring therapy, and for defining efficacy of novel agents in the autoimmune rheumatic diseases.

Abstract: This document relates to materials and methods for assessing and/or treating subjects (e.g., subjects having autoimmune diseases). For example, materials and methods for determining if a subject (e.g., a human having an autoimmune disease) has one or more antibodies that can be used to identify the subject as having a lower risk of cancer or as having a higher risk of cancer are provided. Materials and methods for treating a subject (e.g., a human) identified as having a higher cancer risk for cancer are also provided.

Abstract: The present disclosure provides, among other things, compositions (e.g., autoantibodies) that inhibit the growth, viability, or mobility of (invasion by) a cancer cell. Also provided are applications, such as therapeutic and diagnostic methods, in which the agents are useful, as well as screening methods for identifying autoantibodies useful in the applications.

Abstract: Autoimmune diseases are thought to be initiated by exposures to foreign antigens that cross-react with endogenous molecules. Analyses of peripheral blood lymphocytes and serum suggested that mutations in autoimmune antigen targets sparked cellular immunity and cross-reactive humoral immune responses. Acquired immunity to autoimmune antigens can help control naturally occurring cancers.

Abstract: In one or more embodiments, the present invention provides a novel biomarker which provides a link between a distinct clinical phenotype and a biochemical effect of an autoantibody on an enzyme implicated in disease pathogenesis. In particular, the present invention provides an isolated or purified human autoantibody to PAD3 protein. Methods of diagnosis of subjects for rheumatoid arthritis (RA) using these antibodies as well as diagnosis of the severity of RA in the subject, and methods for monitoring treatment of a subject with RA are also provided. The biomarkers provided herein are also useful in the diagnosis of connective tissue-interstitial lung disease (CT-ILD) in patients having or suspected of having RA.
