Aim: The present study aims at preparation of CARP antibody and analysis of CARP expression pattern.
Methods: Through bioinformatics analysis the antigenicity of CARP, 279 bp cDNA fragment coding CARP N-terminal 93 amino acid was amplified by RT-PCR from mouse heart RNA, then cloned into pET-28b to construct the prokaryotic expression pET 28b-CARP N93. The plasmid was transformed into E.coli(BL21). The target fusion protein was expressed with induction of IPTG, and purified by affinity chromatography. The antiserum against CARP was obtained from the mice immunized with CARP. CARP expression patterns were examined by Western blot and immunofluorescence.
Results: Prepared CARP antibody; CARP specific expression in mouse heart and mainly localized in the nucleus in rat cardiac primary cells.
Conclusion: Successfully generated CARP antibody and examined the expression pattern. The present study has laid a foundation for functional study of CARP.

Immunological memory in a teleost fish: common carp IgM B cells differentiate into memory and plasma cells.
Front Immunol

Article Synopsis
- All vertebrates, from ancient fishes to mammals, possess adaptive immunity and immunological memory, although the specific responding cells in fish have not been clearly defined.
- Researchers infected common carp with a cnidarian parasite and observed that B cells proliferated and showed signs of differentiation, indicating they can form memory cells.
- The study revealed that these memory B cells can persist for at least six months, alongside identifying a distinct population of plasma cells, suggesting that teleost fish possess the necessary immune components for effective long-term disease protection akin to other vertebrates.
Effects of (L.) fruit extract on the profile of hematology of ranchu goldfish ().

Article Synopsis
- The study investigates the effects of calabash fruit extract (BFE) on the growth and blood health of ranchu goldfish, showing that higher concentrations of BFE improve these aspects.
- Group P6, which received the highest BFE concentration, demonstrated the best growth performance and increased levels of specific immune cells (CD4+).
- The findings suggest that BFE could serve as an effective immunostimulant in fish diets, impacting both performance and hematological profiles positively.

CyHV-2 is the pathogen of herpesvirus hematopoietic necrosis (HVHN), resulting in significant economic losses in crucian carp. Although multiple oral vaccines have been developed to prevent CyHV-2, they have not achieved ideal protective effects. To improve the protective effect of oral vaccine, a combination vaccine was conducted by mixing recombinant Saccharomyces cerevisiae displaying ORF132 or ORF25 on the cell surface in a 1:1 ratio.

Article Synopsis
- The common carp, a key freshwater fish in aquaculture, is facing high mortality rates due to bacterial infections linked to intensive farming practices.
- The study analyzed the relationship between infection concentration and immune response by measuring mortality rates, serum LZM, IgM levels, and gene expression in the fish's head kidney.
- Findings revealed that higher pathogen concentrations correlated with increased mortality and immune markers, identifying numerous immune-related genes and pathways that are crucial for understanding carp’s immune response to infections.
