Background/objectives: presents a significant threat to healthy individuals. Titan cell formation, a key virulence factor, is influenced by the nutritional environment and plays a critical role in immune evasion and stress resistance. This study investigates the molecular and biophysical changes in titanized cells grown in nutrient-rich Neurobasal™ medium, a potent inducer of titan cells.
Methods: An integrative approach was used, combining scanning electron microscopy, optical tweezers, fluorescence microscopy, and physicochemical methods to analyze cells grown in Neurobasal™ medium and minimal media.
Results: Cells grown in Neurobasal™ medium exhibited significant differences compared to those grown in minimal media. These included a thicker and more defined polysaccharide capsule, enhanced capsule elasticity, and the secretion of more elastic polysaccharides. Furthermore, cells grown in the enriched medium showed reduced susceptibility to antifungals and delayed mortality in infection models.
Conclusions: adapts to nutritional cues by forming titan cells, thereby enhancing its pathogenicity. Targeting nutritional sensing pathways may offer novel therapeutic strategies against cryptococcal infections.

Mesenchymal stem/stromal cells (MSCs) have been identified as a promising therapeutic option for osteoarthritis, graft vs. host disease and cardiovascular diseases, among others. For widespread application of these therapies, robust and scaled manufacturing processes are required that reliably yield high amounts of high quality MSCs.

Despite the overall conservation of ribosomes across all domains of life, differences in their 3D architecture, rRNA sequences, ribosomal protein composition, and translation factor requirements reflect lineage-specific adaptations to environmental niches. In the domain Archaea, structural studies have primarily focused on non-methanogenic thermophiles and halophiles, leaving it unclear whether these represent the broader archaeal domain. Here, we report the cryo-electron microscopy (cryo-EM) structure of the ribosome from Methanosarcina acetivorans, a previously unreported high-resolution structure from a model mesophilic methanogenic archaeon.

Enterovirus D68 (EV-D68) is an emerging respiratory virus associated with extra-respiratory complications, especially acute flaccid myelitis. However, the pathogenesis of acute flaccid myelitis is not fully understood. It is hypothesised that through infection of skeletal muscles, the virus further infects motor neurons via the neuromuscular junction.

Phosphorus (P) is an essential macronutrient for plant growth and development; however, both its deficiency and excess can be harmful. Although the effects of excess P are still poorly understood, research has shown that plants exposed to excessive levels of P exhibit reductions in stomatal conductance, photosynthesis, and growth. The aim of this study was to investigate the effect of different P concentrations on stomatal responses, photochemical parameters, growth, and development of three Solanum lycopersicum genotypes: wild type, Never ripe (lower sensitivity to ethylene), and Notabilis (deficient in ABA production).
