Split-site ubiquitination gives ZNFX1 new power in RNA defense Recent work by Grabarczyk et al. uncovers the molecular mechanism by which ZNFX1, an interferon-stimulated gene, employs a novel split-site E3 ligase domain structure to ubiquitinate both protein lysi...

Mucosal unadjuvanted booster vaccines elicit local IgA responses by conversion of pre-existing immunity in mice

Nasal vaccines as booster, after i.m vaccination, to improve local IgA production. No additional adjuvant needed (mice and hamsters). Nice paper!

This is where engagement becomes essential. At the very least, communicate back that you actually fully appreciate the work, the literature, or the reviewer's missteps - they aren't infallible either you know !

But "they are smart people, i'm sure they understood". Well, i'm sure most of us are smart people, but i quite often have a hard time appreciating some papers that are outside my immediate -Tcell- comfort zone.
I don't imagine i'm the smartest cat on the block, so it might be a "me" problem.

How is one supposed to interpret a "copy and paste" editorial letter ? Did they even read anything the authors wrote ? Did they understand the work discussed ?

It's incredibly disturbing when journal editors act infallible.

A modicum of engagement, or any sort of scientific discourse, would certainly go along way.

These are simply the moments that make me hate, absolutely hate, doing science - and i have been in it long eough to know better !

'We found that citrullinated MBP160โ€“175 (MBP160โ€“175(cit)), when co-immunized with MOG35โ€“55, indeed no longer suppressed EAE, implying a specific immunomodulatory function for naked MBP160โ€“175 peptides in regulating neuroinflammation'
