Insights into microscopic fabrication, macroscopic forms and biomedical applications of alginate composite gel containing metal-organic frameworks.

Overcoming the poor physicochemical properties of pure alginate gel and the inherent shortcomings of pure metal-organic framework (MOF), alginate/MOF composite gel has captured the interest of many researchers as a tunable platform with high stability, controllable pore structure, and enhanced biological activity. Interestingly, different from the traditional organic or inorganic nanofillers physically trapped or chemically linked within neTtworks, MOFs crystals can not only be dispersed by crosslinking polymerization, but also support self-assembly in-situ under the help of chelating cations with alginate. The latter is influenced by multiple factors and may involve some complex mechanisms of action, which is also a topic discussed deeply in this article while summarizing different preparation routes.

Research progress on the molecular mechanism of immune escape of porcine reproductive and respiratory syndrome virus.

Porcine reproductive and respiratory syndrome (PRRS), caused by the porcine reproductive and respiratory syndrome virus (PRRSV), is a severe and highly contagious disease that results in significant economic losses for the pig industry. Currently, vaccination is one of the most effective methods for controlling PRRS; however, due to the extensive genetic variation of PRRSV and the generation of homologous immunity, vaccines provide protective effects only against homologous strains and lack effective cross-protection against heterologous strains. Furthermore, PRRSV encodes a variety of proteins with immune escape functions, and the mechanisms underlying these functions are complex and not yet fully understood.
