A pyrimidine 5'-nucleotidase deficiency in an adult is reported. Interestingly, the P5'N-1 deficiency was associated to a polymalformative syndrome and was characterized by a chronic, pancytopenic evolution with concomitant dyserythropoiesis.

Targeting the influencing factors in tumor growth and expansion in the tumor microenvironment is one of the key approaches to cancer immunotherapy. Various factors in the tumor microenvironment can in cooperation stimulate tumor growth, suppress anti-tumor immune responses, promote drug resistance, and ultimately enhance tumor recurrence. Therefore, due to the dependence and close cooperation of these axes, their combined targeting can have a greater effect compared to their individual targeting.

CD73, an ectoenzyme responsible for adenosine production, is often elevated in immuno-suppressive tumor environments. Inhibition of CD73 activity holds great promise as a therapeutic strategy for CD73-expressing cancers. In this study, we have developed a therapeutic anti-human CD73 antibody cocktail, HB0045.

CD73, an important metabolic and immune escape-promoting gene, catalyzes the hydrolysis of adenosine monophosphate (AMP) to adenosine (ADO). AMP has anti-inflammatory and vascular relaxant properties, while ADO has a strong immunosuppressive effect, suggesting that CD73 has pro-inflammatory and immune escape effects. However, CD73 also decreased proinflammatory reaction, suggesting that CD73 has a positive side to the body.

Streptococcus oralis is a commensal oral bacterium that acts as an opportunistic pathogen, causing systemic diseases, such as infective endocarditis and aspiration pneumonia. However, the specific molecular mechanisms underlying its transition from commensal to pathogenic state remain unclear. In this study, to further elucidate the mechanisms underlying virulence expression, we identified and characterized the cell surface-associated ecto-5'-nucleotidase (Nt5e) in S.

Background: Despite the development of various therapeutic approaches over the past decades, the treatment of glioblastoma multiforme (GBM) remains a major challenge. The extracellular adenosine-generating enzyme, CD73, is involved in the pathogenesis and progression of GBM, and targeting CD73 may represent a novel approach to treat this cancer. In this study, three-dimensional culture systems based on three hydrogel compositions were characterized and an optimal type was selected to simulate the GBM microenvironment.
