Abstract

The immunocytochemical distribution of several neuronal and glial antigens was investigated in the cerebellum of the developing and adult rabbit. Neurofilament positive neurons appeared at embryonic day (E) 25. Purkinje cells transiently expressed neurofilament polypeptides from postnatal day (P) 0 to 15. At later postnatal ages, staining was localised to the parallel fibres, the axonal arbors of the basket cells and fibres of the white matter. Neuron specific enolase (NSE) immunoreactivity was first detected at E25. At P0 Purkinje cells were positive and their staining intensity increased up to P25. From P30 to adulthood virtually all cells in the molecular and Purkinje cell layers were stained. Scattered PGP 9.5-immunoreactive neurons appeared in the cerebellar anlage at P25. Purkinje and Golgi cells were labelled by P0. Synaptophysin immunoreactivity was first observed at P0 in the form of a fine punctate reaction surrounding the perikarya and proximal dendrites of Purkinje cells. By P10, it became particularly intense within the cerebellar glomeruli of the granular layer. Neurons of the deep cerebellar nuclei expressed NSE and PGP 9.5 starting from E25. GFAP and S-100 immunoreactivities were first detected at P10. GFAP-immu...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.
