Comparison of uridine and N1-methylpseudouridine mRNA platforms in development of an Andes virus vaccineNature communications · 2024
Summary (written by the submitters)
Andes virus (ANDV) is a rodent-borne zoonotic orthohantavirus endemic in South America that causes hantavirus pulmonary syndrome in humans, with up to a 40% case fatality rate. We developed ANDV mRNA vaccines based on the M segment of the viral genome that codes for glycoproteins Gn and Gc in a single open reading frame of glycoprotein precursor (GPC).

We generated RNAs either with regular uridine (U-mRNA) or N1-methylpseudouridine (m1Ψ-mRNA). Mice immunized by either ANDV U-mRNA or m1Ψ-mRNA developed similar germinal center responses in lymph nodes. Single cell RNA and BCR sequencing of germinal center B cells from vaccinated mice demonstrated similar levels of activation, except an additional cluster of cells exhibiting strong interferon response that was present in animals vaccinated with U-mRNA but not m1Ψ-mRNA. Furthermore, similar immunoglobulin class-switching and somatic hypermutations were observed for the two vaccines. Golden Syrian hamsters were immunized intramuscularly with 2 doses of the vaccines on days 0 and 21. The titers of Gn/Gc-binding antibodies were moderately greater for U-mRNA construct than for m1Ψ-mRNA construct, however, the titers of ANDV-neutralizing antibodies were equivalent. Vaccinated animals were challenged with a lethal dose of ANDV at 21 days after the boost, along with the naïve control group. All control animals succumbed to infection whereas all vaccinated animals survived without any detectable disease or viral load. The data demonstrate the development of effective vaccines against ANDV and the lack of a significant effect of m1Ψ mRNA modification on immunogenicity and protection in the hamster model.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE240062_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1002186 and SRA study SRP453340. Searching any of these in the dataset finder brings you back here.

Study design
16 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 16 sample titles: 16 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
