On the balance of knowledge - Nature Reviews Immunology Ruslan Medzhitov shares his thoughts on the balance between generating data and developing theories in immunology, with a focus on exploring the rules that govern complex systems.

I'd like to see this problem analysed at the single cell multi-omics level
'Advances in research technolo- gies are crucial for the scientific enterprise but have an unintended consequence: when pow- erful techniques become widely available, they tend to be applied without a good question in mind.'

Glucocorticoids suppress early lung inflammation and impair control of SARS-CoV-2 in non-human primates In severe cases of COVID-19, glucocorticoid treatment improves clinical outcomes. However, in non-hospitalized patients, glucocorticoids have limited benefit and may impair viral clearance. Here, we u...

In this new paper by @nelson-lab.bsky.social, we found that pre-exposure of NHP to glucocorticoids impairs control of SARS-CoV-2 and is associated with reduced pDC, eosinophil and γδT cell responses.

How tumours trick the brain into shutting down cancer-fighting cells Lung cancer in mice hijacks neurons to send a signal that subdues the immune system, study finds.

'Tumours boost their own growth by attracting & commandeering nearby sensory nerves (...) By ‘plugging into’ tumour cells, these nerves can send a signal to the brain that subdues the protective activity of immune cells at the tumour site — allowing the cancerous cells to proliferate unchecked'

Important paper by Björn
Corleis. For decades a central tenet of #tuberculosis immunology has that IFNγ-driven iNOS expression in macrophages is the primary mechanism of bacterial control. Turns out this is really only in mice and maybe cattle. It’s not true in most species including humans an NHP.

Check out our new paper with @nelson-lab.bsky.social. We used scRNAseq to profile the function of Mtb peptide-specific T cells from NHP and human lung granulomas. Beyond IFNγ, Mtb-specific T cells make a bunch of unexpected stuff, and human and NHP cell are really similar.

What we’ve got here is failure to communicate - some macrophages you just can’t reach!

Multiple features of granulomas limit effective T cell:MΦ interactions, posing a major barrier for vaccine-mediated protection.
