Early development of noradrenaline-containing sympathetic nerves in the choroid plexus system of the rabbit

Cell and Tissue Research
M Lindvall, C Owman

Abstract

The development of the adrenergic sympathetic innervation of the rabbit choroid plexus system was studied prenatally and up to two months after birth by a combination of fluorescence histochemistry (formaldehyde and glyoxylic acid methods) and quantitative enzymatic determinations of noradrenaline. The first signs of adrenergic nerves are found in the plexus of the third ventricle within the first day after birth. Fluorescent fibres subsequently appear in the choroid plexuses of the lateral ventricles (five days post partum) and the fourth ventricle (two weeks post partum). During the following development nerve fibres grow along blood vessels to form a plexus located between small vessels and the overlying epithelium. The nerve plexus, with varicose axon terminals, is fully developed at three weeks post partum, and maturation is then established by an increase in the number of terminals within the network of axons. There is a good agreement between (a) the development of the fluorescent nerves and histochemically visible adrenergic innervation, and (b) the tissue level of noradrenaline in the various choroid plexuses. Against the background of available information on the development of the secretory functions in choroid plexu...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.
