Dopamine D2 receptor mRNA is expressed in maturing neurons of the human hippocampal and subicular fields

Neuroreport

Abstract

Pyramidal neurons of the adult and fetal hippocampus and subicular fields were shown to express D2 mRNA using non-radioactive in situ hybridization histochemistry. At the earliest developmental stages examined (embryonic week (E) 13), cell packing within the CA1 region is dense and immature neuroblasts express D2 mRNA at high levels, as do more mature pyramid-like neurons in the deep aspect of the pyramidal cell layer. With development (E19 and E24), cell packing density is reduced, maturing neurons of the pyramidal layer are prominently D2 mRNA positive, while the majority of immature cells lining the superficial layer are D2 mRNA negative. In Layer II of the presubiculum there is a high density of immature D2 mRNA negative cells at E13 with D2 mRNA positive cells located on the periphery of the clusters. By E24, the cells in the layer II clusters are larger, express D2 mRNA, and D2 mRNA negative cells are rarely observed. Thus, expression of D2 mRNA in humans is an early and permanent feature of pyramidal neurons of these regions.

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.
