Effects of levamisole on the proliferation of thymic lymphocyte subpopulations

I G OtternessM L Bliven


The ability of levamisole to enhance proliferation of murine lymphocyte preparations stimulated by concanavalin A was examined. Levamisole substantially augmented the proliferation of C57Bl/6 thymic lymphocytes, but had only marginal effects on the proliferation of splenic lymphocytes. The possibility that this difference was related to the degree of cell maturation was examined by peanut agglutinin fractionation of the thymic lymphocytes. Levamisole was found to stimulate proliferation most effectively in the mature fraction. However, since the focus of levamisole activity might be on macrophages, also shown to be present in preparations of splenic and thymic lymphocytes and in both PNA separated fractions, the drug's activity was compared to several macrophage replacements: LAF-IL 1, 2-mercaptoethanol, and added splenic adherent cells. Added plastic adherent cells and 2-mercaptoethanol were effective in augmentation of proliferation of both mature and immature populations whereas LAF-IL 1 like levamisole was most effective on the mature population.

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 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.

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.


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.
