The influence of preganglionic nerves on the superior cervical ganglion of the rat

Neuroscience Letters
C E Hill, I A Hendry


Sympathetic neurones grown in tissue culture with non-neuronal cells become cholinergic. Such a change from an adrenergic to cholinergic character does not occur in vivo and it has been suggested that this may be due to the determination of the adrenergic character by electrical activity. Electrical activity in the superior cervical ganglion by young rats were prevented by transection of the preganglionic nerve trunk. In no case did this operation result in an increase in the intrinsic choline acetyltransferase (CAT) of the ganglion. We conclude that electrical activity is not the factor responsible for the difference between in vivo and in vitro results.

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.
