Abstract

We produced a series of T cell hybridomas that produce IL-2 when cultured with syngeneic APC coupled to FITC or TNP. These hybridomas are hapten specific and Ia restricted. The hybridomas were used to detect hapten-bearing APC in draining lymph nodes of mice sensitized with trinitrochlorobenzene or FITC in vivo. Hapten-bearing APC capable of stimulating the hybridomas were detectable in draining lymph nodes of hapten-painted mice within 3 h after sensitization. The ability of lymph node APC to stimulate the hybridomas peaked at 24 h and declined by 48 h. The dendritic cell subpopulation was the subpopulation of cells that were found in the regional lymph nodes of hapten-painted animals that were capable of stimulating the hybridomas to produce IL-2. Prior treatment of the skin with low dose UVB irradiation before epicutaneous application of contact sensitizers significantly reduced the capacity of hapten-bearing APC to stimulate the hybridomas. This observation was corroborated by results obtained from flow microfluorometry analysis of lymph node cells from FITC-sensitized mice. Lymph node dendritic cells obtained from FITC-painted mice contain a brightly staining group of cells by flow microfluorometry analysis. Lymph node den...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.
