Properties of Fcgamma receptors in normal and malignant human tissues

Scandinavian Journal of Immunology

Abstract

Properties of the IgG receptors were studied by treating tissue sections or suspensions of peripheral mononuclear cells with various chemical reagents and determining changes in their ability to react with IgG-sensitized erythrocytes (EA). A heterogeneity of the Fc receptors was revealed. Iodoacetamide, 2-mercaptoethanol, sodium azide, EDTA, and a pH varying from 6.0 to 8.2 had no effect on Fc receptors in sections of normal lymphoreticular tissue and malignant tissue. Formaldehyde, low pH, and high salt concentrations affected receptor activity to various degrees. Receptors in liver sections and on monocytes were generally more resistant than receptors in spleen sections and on B lymphocytes. Receptors in malignant tissue behaved either like receptors in spleen or like receptors in liver. Although all tissues were sensitive to periodic acid, the Fc receptors in malignant tissue were always more resistant.

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
