Treatment of a genetic liver disease in mice through transient prime editor expression

This paper demonstrates transient prime editor expression in mice to correct a genetic liver disease, reducing blood phenylalanine levels below the therapeutic threshold.

Transient growth factor expression via mRNA in lipid nanoparticles promotes hepatocyte cell therapy to treat murine liver diseases

The paper demonstrates that transient mRNA-based growth factor expression in lipid nanoparticles enhances PHH engraftment and liver function in murine liver disease models.

Broadly neutralizing antibody induction by non-stabilized SARS-CoV-2 Spike mRNA vaccination in nonhuman primates

Non-stabilized SARS-CoV-2 Spike mRNA vaccination in macaques induces B cell lineages targeting conserved epitopes on Omicron variants or cross-neutralizing epitopes on Sarbecoviruses.

Growth Hormone Accelerates Recovery From Acetaminophen-Induced Murine Liver Injury

This study shows that growth hormone treatment accelerates liver recovery in male mice after acetaminophen overdose, outperforming standard-of-care N-acetyl cysteine.

VEGFA mRNA-LNP promotes biliary epithelial cell-to-hepatocyte conversion in acute and chronic liver diseases and reverses steatosis and fibrosis

Multivalent Human Cytomegalovirus Glycoprotein B Nucleoside-Modified mRNA Vaccines Demonstrate a Greater Breadth in T cell but not Antibody Responses

This study evaluates multivalent HCMV gB mRNA vaccines in rabbits, finding increased T cell responses but no improvement in antibody breadth.

Mutation-Guided Vaccine Design: A Strategy for Developing Boosting Immunogens for HIV Broadly Neutralizing Antibody Induction

The paper demonstrates a mutation-guided vaccine strategy that induces HIV broadly neutralizing antibodies in mice by selecting for rare B cell lineage mutations.

Immunity to seasonal coronavirus spike proteins does not protect from SARS-CoV-2 challenge in a mouse model but has no detrimental effect on protection mediated by COVID-19 mRNA vaccination

This study investigates whether immunity to seasonal coronavirus spike proteins protects against SARS-CoV-2 in mice and affects mRNA vaccine efficacy, finding no increased protection but no detrimental effect on vaccination.

Molecular fate-mapping of serum antibodies reveals the effects of antigenic imprinting on repeated immunization

This study uses molecular fate-mapping to show that repeated immunization preferentially reuses initial B cell clones over recruiting new ones, with imprinting effects decreasing as antigenic distance increases.

A universal influenza mRNA vaccine candidate boosts T-cell responses and reduces zoonotic influenza virus disease in ferrets

This study evaluates a T-cell-inducing mRNA vaccine against influenza, showing it boosts T-cell responses and reduces disease in ferrets.

Nucleoside-modified mRNA-based influenza vaccines circumvent problems associated with H3N2 vaccine strain egg-adaptation

This study compares H3N2 vaccine efficacy between mRNA-LNP and egg-based vaccines, finding that mRNA-LNP vaccines elicit better neutralizing antibodies and protection against wild-type H3N2 virus.
