Abstract

It was found that anti-MM2 serum, which had been prepared by immunizing C3H/He mice with syngeneic MM2 mouse mammary ascites tumor, detected molecules of 44-46,000 and 12,000 daltons on EL4 leukemic cells and on C57BL/6 lymph node cells, as well as on somatic cell hybrids between the MM2 and mouse L cells. Experiments with a known rabbit anti-mouse beta2-microglobulin serum showed that the two molecules detected by anti-MM2 serum were hydrophobically associated with each other in membrane extracts; thus, the antigen detected by anti-MM2 serum was structurally similar to H-2K and D antigens. Preclearing of lysates from C57BL6 lymph node cells with a mixture of anti-H-22, anti-H-2.33, and anti-H-2.28 sera did not remove the "H-2-like" antigen, indicating that the antigen was distinct from the H-2Kb and Db molecules. Neither C3H/He nor B10.BR lymph node cells expressed the "H-2-like" antigen, but B10.A(4R) and B10.AM lymph node cells did possess the antigen. Absorption of anti-MM2 serum with EL4 cells abolished the capacity of the absorbed serum to precipitate the "H-2-like" antigen activity on C57BL/6 lymph node cell extracts and reduced the "H-2-like" radioactive peaks of the hybrid cells. These results indicate that there are a...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.
