Evidence for dopaminergic modulation of pancreatic polypeptide secretion in man

Life Sciences
J R SowersI L Taylor


This study examines the role of dopaminergic mechanisms in the regulation of human pancreatic polypeptide (hPP) secretion in 11 normal male volunteers. Administration of domperidone (20 mg iv), an extracerebral inhibitor of dopamine receptors, resulted in a hPP rise (p less than 0.05) within 10 min and a peak response (p less than 0.01) at 15 min after drug administration. Administration of the dopaminergic agonist, bromocriptine, 2.5 mg tid for 4 days eliminated hPP responses to isometric handgrip exercise in these 11 volunteers. These results suggest that dopaminergic mechanisms may exert a tonic inhibitory effect on hPP secretion in normal subjects.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
