Background and Purpose Adenosine as a signalling molecule modifies blood–brain barrier (BBB) tightness in pathological conditions. Our aim was to investigate the direct and polarized effects of adenosine on the BBB using co‐culture and in vivo models. Experimental Approach The expression of adenosine receptors was measured by qRT‐PCR.

Inhibition of Escherichia coli cytidine deaminase by a phosphapyrimidine nucleoside.
The nature of the interaction between Escherichia coli cytidine deaminase and the phosphapyrimidine nucleoside 1 has been studied kinetically and spectrophotometrically. Compound 1 was designed as a transition-state analog, and is a potent, slow-binding inhibitor of cytidine deaminase (Ashley, G. W., and Bartlett, P. A. (1982) Biochem. Biophys.

Combined familial adenosine deaminase and purine nucleoside phosphorylase deficiencies. [PDF]
We studied an Arab family in which two infants died of severe combined immunodeficiency caused by adenosine deaminase (ADA) deficiency. One infant had purine nucleoside phosphorylase (PNP) activity in the leucocytes only half that of normal. Four other infant siblings had previously died from infections before the age of 2 months.

Transgenic selection and underlying mechanisms in apicomplexan parasites
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Lymphospecific toxicity in adenosine deaminase deficiency and purine nucleoside phosphorylase deficiency: Possible role of nucleoside kinase(s) [PDF]
Inherited deficiencies of the enzymes adenosine deaminase (adenosine aminohydrolase; EC 3.5.4.4) and purine nucleoside phosphorylase (purine-nucleoside:orthophosphate ribosyltransferase; EC 2.4.2.1) preferentially interfere with lymphocyte development while sparing most other organ systems.

A large intracellular drug‐repurposing screen identifies a potent synergy between 5‐fluoro‐2′‐deoxycytidine and rifapentine, acting through dual host–pathogen targeting to reduce Staphylococcus aureus burdens across strains, cell types, and infection models (created with BioRender).

Repurposing Purine Analog Antivirals to Modulate Serum Uric Acid: Evidence From Real‐World Data
ABSTRACT Xanthine oxidase (XO) inhibitors remain the standard pharmacologic therapy for hyperuricemia. However, additional enzymatic components of the purine degradation pathway may contribute to uric acid synthesis. Guanine deaminase (GD) catalyzes the conversion of guanine to xanthine, providing substrate for downstream oxidation by XO.

Emerging Roles of Adenosine Metabolism in Astrocytes During Brain Injury
Adenosine, as a key metabolic and neurotransmitter in the brain, has become an important therapeutic target for improving the efficacy of immunotherapy for stroke. However, gaps in knowledge about its metabolic pathways have become a key factor limiting its clinical translation.

Protective mechanisms of Camellia oleifera seed cake extract (SCE) against hyperuricemia and renal injury via modulation of uric acid metabolism, Nrf2/Keap1 signaling, and NLRP3 inflammasome activation. ABSTRACT Camellia oleifera seed cake is a major byproduct of the oil industry, often underutilized despite its richness in bioactive compounds.
