Evaluation of Adjuvant Effect of Cytosine-Guanosine-Oligodeoxynucleotide in Meat-Type Chickens Coadministered <i>In Ovo</i> with Herpesvirus of Turkey Vaccine
Boone, A. C., Kulkarni, R. R., Cortes, A. L., Gaghan, C., Mohammed, J., Villalobos, T., … Gimeno, I. M. (2024, February 1). VIRAL IMMUNOLOGY, Vol. 2.
author keywords: herpesvirus of turkey; toll-like receptor 21; cellular immunity; immunocompetence; in ovo vaccination; chickens
TL;DR:
Adding cytosine-guanosine oligodeoxynucleotides (CpG ODNs) to the HVT vaccine could enhance the adjuvant effect of HVT, and CpG ODN administration in ovo with or without HVT significantly increased frequencies of activated CD4+ and CD8+ T cells.
