ABSTRACT
Human immunodeficiency virus (HIV) infection is still a global public health issue, and the development of an effective prophylactic vaccine inducing potent neutralizing antibodies remains a significant challenge. This study aims to explore the inflammation-related proteins associated with the neutralizing antibodies induced by the DNA/rTV vaccine. In this study, we employed the Olink chip to analyze the inflammation-related proteins in plasma in healthy individuals receiving HIV candidate vaccine (DNA priming and recombinant vaccinia virus rTV boosting) and compared the differences between neutralizing antibody-positive (nab + ) and -negative(nab-) groups. We identified 25 differentially expressed factors and conducted enrichment and correlation analysis on them. Our results revealed that significant expression differences in artemin (ARTN) and C-C motif chemokine ligand 23 (CCL23) between nab+ and -nab- groups. Notably, the expression of CCL23 was negatively corelated to the ID50 of neutralizing antibodies and the intensity of the CD4+ T cell responses. This study enriches our understanding of the immune picture induced by the DNA/rTV vaccine, and provides insights for future HIV vaccine development.
