A comparison of EA-Rosette formation on lymphocytes using rabbit and human sensitizing antibodies

Scandinavian Journal of Immunology

Abstract

The IgG receptors of peripheral blood lymphocytes were studied to determine whether those detected by a rabbit anti-ox erythrocyte antibody (EARa) and a human anti-human erythrocyte antibody (EAHu) were the same. With cells separated by Ficoll-Hypaque and freed of adherent cells by exposure to plastic surfaces, both EA systems gave similar numbers of rosettes. Mixed rosetting occurred when both types of sensitized cells were added simultaneously. EAHu and EARa rosettes showed similar kinetics of formation. Depletion of rosette-forming lymphocytes was possible by using both systems, and depletion by one system showed depletion in the other. sIg-bearing lymphocytes were also removed, the amount of depletion being dependent on the degree of RBC sensitization with antibody. EAHu and ERRa rosettes were equally inhibited by IgG of a given species of subclass. Normal human and rabbit IgG were more inhibitory than bovine or guinea-pig IgG. All of the human subclasses inhibited, but IgG and IgG3 were more inhibitory than IgG and IgG4. These results indicate that Fc gamma receptors on human lymphocytes react with an IgG configuration that is present on IgG of many species, although it is variably expressed among them. Human IgG1 and rabb...Continue Reading

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
