Expression of CD103 facilitates localization and activation of CD4+ T cells within Mycobacterium tuberculosis lung-lesions from @rmortensenssi.bsky.social and colleagues www.mucosalimmunology.org/article/S193...
Pleased to see this out now in @jem.org 🔬
We characterise the early immune response during M. tuberculosis infection in mouse models and demonstrate a detrimental role for type I interferon activated neutrophils in TB lesions. Thanks to all involved @crick.ac.uk and i3S, Porto.
A nice discussion here of our work on the early immune response in M. tuberculosis infection and the great recent paper from @bengern.bsky.social et al
Congratulations on a very nice story, Will! I agree an excellent writeup by Dr. Andrea Cooper. It's been great to learn a ton from your paper, and see so many parallels with our findings
Insights from Andrea Cooper: Mtb drives expression of type I IFN–mediated #neutrophil accumulation, which limits interaction btwn CD4 T cells & macrophages. Failure to limit type I IFN very early in the process allows rapid progression of disease rupress.org/jem/article/...

Asthma is a chronic disease characterized by acute, intermittent, recurrent episodes of airway inflammation. A decade of work developing the tools, techniques and collaborations needed to figure out how CD4+ T cells in the lungs propagate disease can be found here:

A recent study from the Gerner and Urdahl labs at UW and @seattlechildrens.org uncovers fundamental determinants of tuberculosis lung pathology. This has important implications for new strategies to prevent or treat tuberculosis.

Happy to share our new pre-print, led by PhD student Linh Pham! We examine inhibition of MHC II expression by NRF2 during Mtb infection and its impact on innate-adaptive crosstalk. Special thanks to the Behar lab who helped us set up a T cell co-culture system for the project! #TB #immunology
We are hiring! The Dept of Microbiology and Molecular Genetics is looking for faculty at the Assistant or Associate professor level (tenure track). Please consider joining our vibrant microbiology and immunology community at the University of Pittsburgh School of medicine

Thanks, @alissarothchild.bsky.social!
In @jem.org, @bengern.bsky.social et al. show that the early interplay between #neutrophils & CD4 T cells is pivotal in determining #TB pathology, and that depleting neutrophils can improve outcomes even at late timepoints, which has therapeutic relevance rupress.org/jem/article/...

I’m excited to announce that our paper, describing early and opposing roles for neutrophils and CD4 T cells in determining #TB lesion structure, is out at @jem.org ! Huge thanks to my lab, and the Urdahl, @michael-gerner.bsky.social, and Aitchison labs who made this possible

Tuberculosis continues to impair quality of life long after the antibiotics have finished...
Need to work out how to prevent and treat these post-TB sequelae.

Happy to share a preprint from the Angelo lab many years in the making. Read on for a saga of multiplexed imaging, immunometabolism, and TB granulomas with some fun side quests into the realms of geographical information sciences and transcriptomics… (1/20) doi.org/10.1101/2025...
Congrats on a really cool story, Erin!
Very excited for this story to be out!! Check out our dissection of how type I IFN promotes NET release, which contributes to Mtb pathogenesis and is associated with granuloma necrosis. Congratulations to all authors!! www.cell.com/cell-host-mi...
Graphical summary of our paper. In mice, prior lower airway exposure to diverse inflammatory stimuli, including chronic bacterial infections such as M. tuberculosis, acute bacterial infections such as pulmonary S. aureus, viral infections such as Influenza A, type-II allergic responses such as the OVA-Alum model, activation of pulmonary TLR9 by CpG or pulmonary TLR1/2 by Pam3CSK4 leads to reduced viral burden upon subsequent infection with SARS-CoV-2 (SCV2). (2) This SCV2 restriction occurs prior to induction of SCV2-specific adaptive immune responses and is mediated through innate immune responses, including the induction of IFN-I, TNFα and IL-1 and sustained changes to the TRM (Tissue resident macrophage) cellular compartment and the pulmonary epithelium. (3) Innate cytokine and TLR signaling to both recruited immune cells and the pulmonary epithelium creates a microenvironment in the lung that limits early replication of SCV2. IFN-I signaling to pulmonary ECs (epithelial cells) increases expression of interferon-stimulated genes, that likely cell-intrinsically limit viral replication. TNF- or IL-1 suppress SCV2 independently of IFN-I signaling. TNF acts exclusively through radio-resistant cell types such as the lung epithelium, whereas IL-1 affords control both direct and indirectly, through either stromal and hematopoietic cell types, to restrict overall early SCV2 burden.

My new book, Everything Is Tuberculosis, explores the history of our deadliest infectious disease. It's also about our horrifying present: TB still kills kills over a million people per year, even though it's been curable since the 1950s.

Ok, in time for the International Day of Pride in STEM, here's a starter pack of LGBTQ+ immunologists. Since not everyone is open (or able to be open) about their identities, we're only adding people by request, so let me know if you'd like to be added #Immunosky #PrideInSTEM 🏳️🌈🏳️⚧️ go.bsky.app/7WTavcd
Hi! Would you include me in the global health starter pack?
