Big day for foundational glycoRNA research, with two preprints published in Nature EMM. Both urge greater analytical rigour in the field.
1. RNA-associated glycoconjugates highlight potential
ambiguities in glycoRNA analysis
2. Proteins are a source of glycans found in preparations of glycoRNA

#glycotime We hope our b2b publications serve as a heads-up for the #glycoRNA community, and drive the field forward constructively. Links👇

We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...
DNASE1L3 surveils mitochondrial DNA on the surface of distinct mammalian cells
The extracellular space is a critical environment for discriminating self versus non-self nucleic acids and initiating the appropriate immune responses through signaling cascades to relay information ...
