Regeneration of sensory neurons after spinal cord injury depends on the function of dividing neuronal-glial antigen 2 (NG2)-expressing cells. We have shown that increases in the number of dividing NG2-positive cells through short-term pharmacologic inhibition of matrix metalloproteinases contributes to

Extracellular nucleotides acting through P2 receptors facilitate natriuresis. To define how purinergic mechanisms are involved in sodium homeostasis, we used transgenic (TG) mice that globally overexpress human CD39 (hCD39, NTPDase1), an ectonucleotidase that hydrolyzes extracellular ATP/ADP to AMP, resulting in

SAMHD1 is a nuclear deoxyribonucleoside triphosphate triphosphohydrolase that contributes to the control of cellular deoxyribonucleoside triphosphate (dNTP) pool sizes through dNTP hydrolysis and modulates the innate immune response to viruses. CyclinA2-CDK1/2 phosphorylates SAMHD1 at Thr-592, but how this modification controls
