In Vitro Evaluation of Toxicant Influences on the Immune System.

Current Protocols in Toxicology
Jane Kasten-Jolly, David A Lawrence

Abstract

Culture of human peripheral blood mononuclear cells (PBMCs) still remains a convenient and sensitive method for measurement of a person's immune system health. Basic elements of the process, namely PBMC purification and culture medium formulation, were first reported in the late 1960s, and the utility of the method for clinical application was reported in the 1970s. Clinically, the approach can provide information about the ability of an individual's immune system to fight off attacks by various pathogens. Over the years, the method has undergone many improvements, which have been aided by advancements made in flow cytometry technology and the development of fluorescent reagents. The protocols presented here describe flow cytometry-based techniques for PBMC culture that can be employed to determine the impact of various environmental toxicants on the immune system. A major advantage of these procedures is that they will provide information about a toxicant or drug through in vitro methods. As the relationship between exposures to certain toxicants and an individual's response to vaccinations has been of concern, one of the protocols described shows how to test an environmental toxicant for potential modification of the immune r...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.
