Control Strategies in Guanine Biocrystallization

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

open access: yesAdvanced Science, Volume 13, Issue 35, 24 June 2026.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

Insights into phosphate cooperativity and influence of substrate modifications on binding and catalysis of hexameric purine nucleoside phosphorylases. [PDF]

open access: yesPLoS ONE, 2012
The hexameric purine nucleoside phosphorylase from Bacillus subtilis (BsPNP233) displays great potential to produce nucleoside analogues in industry and can be exploited in the development of new anti-tumor gene therapies.

Boron‐10 carriers and their applications in boron neutron capture therapy

open access: yesPrecision Radiation Oncology, Volume 10, Issue 2, Page 205-241, June 2026.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

Structural insights into urocanate reductase using room‐temperature X‐ray crystallography

open access: yesActa Crystallographica Section D, Volume 82, Issue 6, Page 603-614, June 2026.
The active‐site dynamics of the microbial enzyme urocanate reductase were revealed by room‐temperature X‐ray crystallography.Urocanate reductase (UrdA) is a bacterial enzyme that converts urocanic acid to imidazole propionate. Its catalytic residue Arg411 undergoes a large conformational change in the substrate‐bound versus product‐bound states.

Metabolic Strategies Under Heat Stress in Non‐Adapted and High‐Temperature‐Adapted Lines of a Marine Diatom

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
Proteomics reveal Chaetoceros simplex‐evolved populations adopt a conservative, resource‐recycling strategy when exposed to above‐optimal temperatures. This involves downregulating biosynthesis, which helps the organism withstand heat stress. However, this strategy may limit their ability to adapt to high temperatures in environments with low nitrate ...

Gene Expression and Structural Differences Underpinning Black and White Colouration in Spiders

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The presence of multiple color variants within a single population, known as color polymorphism, is a striking example of intraspecific phenotypic variation and a model for studying evolutionary processes. These processes depend on the underlying mechanisms such as the genes and pigments involved; but we currently lack such information for non‐

Tri-Cyclic Nucleobase Analogs and Their Ribosides as Substrates of Purine-Nucleoside Phosphorylases. II Guanine and Isoguanine Derivatives

open access: yesMolecules, 2019
Etheno-derivatives of guanine, O6-methylguanine, and isoguanine were prepared and purified using standard methods. The title compounds were examined as potential substrates of purine-nucleoside phosphorylases from various sources in the reverse ...

Luminescence of N2,3‐etheno‐2‐aminopurine Embedded in Polyvinyl Alcohol Films at Room Temperature

open access: yesLuminescence, Volume 41, Issue 5, May 2026.
The spectral characteristics of N2,3‐etheno‐2‐aminopurine immobilized in poly(vinyl alcohol) films are presented. Direct excitation to the triplet state and the occurrence of room‐temperature phosphorescence were observed. These findings could be useful for developing tools to study biomolecules that are unstable under high‐energy excitation.

Emerging Roles of Adenosine Metabolism in Astrocytes During Brain Injury

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
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.
