No cDC1, no worries: cDC2 and cross-dressing prime T cells in response to mRNA-LNP vaccination
April 29, 2026
cDC1s play essential roles in CD8+ T cell priming in response to protein- and DNA-based vaccination. However, whether mRNA vaccines function via a similar mechanism remains unknown. In a recent Nature publication, Jo et al. uncovered the mechanisms of CD8+ T cell priming induced by mRNA-LNP vaccines. The researchers began by assessing OT-I...
Agonist anti-CD40 converts Tregs from foes to friends
April 22, 2026
Recent investigations into the use of agonist anti-CD40 for cancer immunotherapy have shown that this treatment not only enhances APC functions, but also reduces regulatory T cells (Tregs) within the tumor microenvironment (TME), despite a lack of CD40 on these cells. Exploring the mechanism by which this occurs, and whether it might contribute...
Stopping the shredder to unlock a novel source of valuable neoantigens
April 15, 2026
Inadequate neoantigen presentation in cancer hampers the endogenous antitumor immune response and the efficacy of immunotherapy. One mechanism that limits the production of immune-targetable antigens is nonsense-mediated mRNA decay (NMD). NMD degrades transcripts with premature termination codons (PTCs), eliminating a potential source of frameshift antigens, which may serve as an immune-evasion mechanism in...
