Effect of Corynebacterium parvum on hemopoietic stem-cell kinetics

Abstract

The intravenous administration of 548 microgram of killed Corynebacterium parvum (C. parvum) into C57BL mice leads to a significant decrease in the number of bone-marrow colony-forming-units in spleen (CFUs) as early as 12 h after the injection of the bacterium. This decrease persisted in varying degrees for 3 weeks. After an initial fall at 24 h, the splenic CFUs exhibited a rapid expansion and reached values 10 times higher than the control range on the ninth day. A significant rise in the number of circulating CFUs, reaching a first peak at 2 h and a second one on the fifth day, was also observed. The proliferative status of femoral CFUs was increased at 48 and 72 h, while that of splenic CFUs presented a significant increase only 48 h after the injection of C. parvum. The sequence of events which were observed in these experiments indicates that an accelerated migration of hemopoietic stem cells from bone marrow to spleen via the blood circulation has to take place.

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.

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.
