Abstract

El Moro Canyon hantavirus (ELMC, previously known as HMV-1) is associated with the western harvest mouse Reithrodontomys megalotis. The interpretation that ELMC is a novel hantavirus was based upon comparisons of the nucleotide sequence of the S genomic segment with those of other hantaviruses. We now show that the ELMC M genome, like the S genome, is genetically similar to but distinct from that of Four Corners hantavirus (FC). The ELMC M genome is 3801 nt in length and encodes a glycoprotein precursor of 1139 amino acids. The G1 and G2 genes are 71 and 73.1% identical to those of FC and the corresponding glycoproteins are 73.5 and 82.3% identical. A portion of the G1 glycoprotein of ELMC that is homologous to an important linear epitope of FC differs from the FC epitope by 10 of 31 residues. That domain and flanking sequences were expressed in Escherichia coli. G1 antibodies from 3 of 19 FC-infected patients showed cross-reactivity with ELMC by Western blot assay. The portion of the ELMC G1 antigen recognized by those antibodies is the region of homology to the FC epitope. These data support our previous interpretation that ELMC is distinct from FC and other hantaviruses.

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.
