An Il12 mRNA-LNP adjuvant enhances mRNA vaccine–induced CD8 T cell responses IL-12 is dispensable for CD8 T cell responses to mRNA vaccination, but an Il12 mRNA-LNP enhances CD8 T cell memory and protection.

mRNAs encoding adjuvant proteins boost immunity. A fantastic study from Hunter et al shows the value of IL12. Study validates original work on this concept, ref below.
Kudos to the authors on this exciting discovery!

ABSTRACT
A leading HIV vaccine strategy requires a priming immunogen to induce broadly neutralizing antibody (bnAb) precursors, followed by a series of heterologous boosters to elicit somatic hypermutation (SHM) and produce bnAbs.
In two randomized, open-label phase 1 human clinical trials, IAVI-G002 in the United States and IAVI-G003 in Rwanda and South Africa, we evaluated the safety and immunogenicity of mRNA-encoded nanoparticles as priming immunogens (both trials) and first-boosting immunogens (IAVI-G002).
The vaccines were generally safe and well tolerated, except 18% of IAVI-G002 participants experienced skin reactions. Priming induced bnAb precursors with substantial frequencies and SHM, and heterologous boosting elicited increased SHM, affinity, and neutralization activity toward bnAb development.
The results establish clinical proof of concept that heterologous boosting can advance bnAb-precursor maturation and demonstrate bAb priming in Africa where the HIV burden is highest.

Two phase 1 clinical trials tested the first steps of a germline-targeting HIV vaccine strategy to induce broadly neutralizing antibodies (bnAbs). A nanoparticle antigen (multicolored sphere) delivered via mRNA activated immune cells, including bnAb precursor B cells (red) and other B cells (blue). The red cells began producing bnAb precursors (red Y-shapes). In one trial (IAVI G002), a second, distinct nanoparticle antigen (larger multicolored sphere) further guided those precursors toward developing the features of bnAbs. Credit: Scripps Research

As a first #ImmunoSky post, I’m excited to share our latest pre-print, by the fantastic Mitchell Zheng!

Our group is interested in virus-specific CD4 T cells, which means we often use in vitro stimulations (like the AIM assay) to find our cells of interest. 🧵 1/9
