The human choroid plexus and autoimmune nephritis

Abstract

The choroid plexus resembles the glomerular basement membrane (GBM) and may be a site of injury or source of antigen in Goodpasture syndrome. Immunohistologic studies were performed on the choroid plexus of a patient with auto-immune nephritis and pulmonary hemorrhage. The studies showed linear deposition of host IgG, IGM, and beta1c. Antibody eluted from the diseased kidney fixed in a linear pattern to normal choroid plexus and could be absorbed by either choroid plexus or GBM. Antibody to choroid plexus fixed to GBM and the linear staining was no longer observed after absorption with GBM or choroid plexus. Antibody to GBM fixed to normal choroid plexus and was obsorbed by both choroid plexus and glomerular basement membrane. The studies suggest an immunologic relationship between choroid plexus and GBM and a role for the choroid plexus in autoimmune nephritis.

COVID-19

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.
