Abstract

We have developed a polyclonal antibody for human papillomavirus (HPV)-related antigens specific to epidermodysplasia verruciformis (EV). Using this antibody, immunohistochemical studies on 12 EV patients were performed. The polyclonal antibody was obtained from rabbits immunized with roughly purified virions of HPV from an EV patient. Sections from 12 EV patients were treated with the polyclonal antibody and then the peroxidase-antiperoxidase method was used to observe the reaction. The observations revealed not only papillomavirus genus-specific common structural antigen (pgs-antigen) but also HPV-related antigens specific to EV. Pgs-antigen was observed in the nuclei of the upper keratinized cells of the benign lesions and HPV-related antigens specific to EV were observed in the nuclei and cytoplasm of both keratinizing cells of the benign lesions and malignant skin tumor cells. HPV-related antigens specific to EV were observed in sections of all 12 EV patients infected by HPV-5, 5-related, 14, 20, 21 and 38, but not in sections of other HPV infections. Using the immunoblot technique, we detected the main papillomavirus structural polypeptide (MW, 58 Kd) and two other unknown proteins (MW, 42 Kd and 33 Kd) in the benign lesi...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.
