A microculture system for generating haemolytic antibody responses from human tonsillar lymphocytes

Journal of Immunological Methods
R J Booth

Abstract

Small numbers of Ficoll-Hypaque purified human tonsillar lymphocytes were stimulated with PWM to produce SRBC-specific PFC in a microculture system. The magnitude of the response varied among different tonsils but was typically between 200 and 1000 PFC/10(6) cells cultured. Little or no response was observed in the absence of PWM. SRBC failed to stimulate a SRBC-specific response and the presence of this antigen in PWM-stimulated cultures depressed the response. The time of the maximum response was inversely related to the number of cells cultured. In addition, the duration of the response was limited by rapid depletion of critical medium requirements and/or build up of inhibitory factors especially when the cell concentration exceeded 5 x 10(5) cells/culture. This effect could be partially overcome by daily feeding of cultures with fresh medium. Fractionation studies indicated a requirement for both T and B cell populations. Constant efficiency of PFC production with respect to cell number could be achieved by the addition of inactivated autologous 'filler' cells. The significance of these results and applicability of the microculture system to a detailed analysis of human antibody responses will be discussed.

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.
