Abstract
Interest for extracellular nucleotides has increased since the pioneer work of Burnstock in the early seventies. Research on cellular functions modulated by purines and pyrimidines has led to the identification and characterization of the different components of purine signaling, namely purinoceptors and ecto-nucleotidases. Receptors for tri- and diphosphonucleosides, known as P2 nucleotide receptors, are designated either P2Y receptors, for those coupled to Gproteins, or P2X for those which are ligand gated-ion channels. Ecto-nucleoside triphosphate diphosphohydrolase (NTPDase; EC 3.6.1.5), previously identified as ecto-ATPase, ecto-ATPDase or CD39, is now considered as the main ecto-nucleotidase responsible for the sequential hydrolysis of beta and gamma phosphates of tri- and diphosphonucleosides. More recently, research has been focused on the development of specific agonists and antagonists to P2 purinoceptors. The need to develop specific inhibitors for NTPDase to understand the role of this enzyme has clearly emerged. This paper covers the development of specific molecules targeting purinergic signaling, more specifically the inhibition of NTPDase and their impact on the different physiological systems.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
RNA Molecules in the Treatment of Human Diseases
Messenger and non-coding RNAs, including long and small transcripts, are mediators of gene expression. Gene expression at the RNA level shows significant aberrations in human diseases, including cancer, leukemia, lymphoma, cardiovascular diseases, and neurological disorders. Human transcripts serve either as biomarkers of diagnosis, prognosis, prediction of treatment response and/or therapy ...read more
