@assert_pub @ProfJohnATodd https://t.co/qfVaVysMDs We propose #T1D is primarily caused by immune responses against microbial-enzyme transketolase which contains key insulin-epitope. Our findings link microbial metabolism of polysaccharides, dysbiosis and antigen-specific immune responses to insulin.

When it comes to #thymus protection against autoimmunity, producing normal thymic regulatory T cells is more important than deleting self-reactive T cells, @UZH_en researchers conclude from studies in mice. Check out the 2021 research: https://t.co/0l7Mh9Yn7j #WeekendReads

New research suggests antimicrobial used to promote livestock growth breeds bacteria more resistant to our natural defences. These findings add to the current body of evidence on the negative impact of antibiotics beyond the gut: https://t.co/kxGRIayUT2

Do you work in biomedical #research? Do you also question your #antibodies? Dodgy antibodies waste time & $$$ + drive the reproducibility crisis. Let's talk about it! We've validated >50❗️Tau antibodies: https://t.co/KFbcYOoFUB Here's what we learnt & why it matters A 🧵 1/n

In Australia, the southern greater glider population’s habitat could be destroyed by logging. "To protect this species, we must prevent further logging of Australia’s native forests," argues a new #LetterToScience. https://t.co/eDid9KkWFT

What is the connection between genes, lifestyle, and disease? That’s the question driving most biomedical research today.

A new study in mice suggests that a majority of IgA in the gut is selected to recognize and react to distinct gut bacterial species instead of demonstrating polyspecificity. @IcahnMountSinai @jeremiahfaith1 https://t.co/8I6Z1Rrmo9

New research from @LabListon investigates the #cytokine network of #IL2. Using a new genetic tool, the authors show that response to IL2 depends on the cellular source. This explains old mysteries of clinical adverse events and provides new targets https://t.co/Mm8vQiakwr

Interesting! Extinction of microbiomes changes fine-tuned ecology of the immune responses to commensals. This is particularly important during infant weaning when regulatory T cells to self epitopes are amplified by commensals mimics. See example for #T1D
