Summary:
When antimicrobial proteins and nanomaterials are combined, they have the potential to produce immunopotentiators, which can boost organism immunity and provide a preventive approach to diseases when taken orally. The study highlighted the effectiveness of CMCS-20a nanoparticles in protecting against grass carp reovirus (GCRV) infection. CXCL20a (CiCXCL20a) from grass carp was loaded onto carboxymethyl chitosan (CMCS) to create the nanoparticles. The low temperature vacuum drying technique (LD-CMCS-20a) significantly increased the survival rate of the grass carp post-GCRV challenge, whereas the high temperature method did not. LD-CMCS-20a improved several immune markers, reduced tissue damage, and decreased viral load in the spleen, according to mechanistic studies. This suggests that CMCS-20a nanoparticles can boost fish defenses against viral threats, providing a novel preventative strategy for such infections.
