Paired single-cell and spatial transcriptional profiling reveals a central osteopontin macrophage response mediating tuberculous granuloma formation - Single Cell Portal
Granulomas are classic manifestations of tuberculosis pathogenesis. They result from an ensemble of immune responses to Mycobacterium tuberculosis infection, but the identities, arrangement, cellular interactions, and regulation of the cells that comprise them have thus far been incompletely understood. To better understand the composition of granulomas, we conducted spatial and single-cell RNA sequencing of granulomas in biopsy specimens from patients with tuberculosis. We found that granulomas consist of concentric transcriptional laminae surrounding areas of central necrosis. We identified distinct populations of granuloma-associated stromal cells, fibroblasts, lymphocytes, mast cells, dendritic cells, neutrophils, and macrophages. Furthermore, gene expression among these cell populations differed by location within granulomas. We used inferential analysis to predict dominant granuloma cell-cell interactions, the activity of major signaling pathways, and transcription factor activities. Using spatial deconvolution, we mapped a conserved pattern of cellular organization dominated by macrophages rich in SPP1/osteopontin expression. Trajectory analysis of macrophage subtypes mapped their differentiation and supported the importance of SPP1 to granuloma macrophage polarization. Using the Mycobacterium marinum-zebrafish model, we found that mycobacterial infection induces spp1 expression in macrophages and that spp1 ablation results in granuloma formation defects and reduced survival in adult animals. Cumulatively, we have identified a dominant macrophage granuloma population as well as its central regulatory gene in human samples and confirmed the importance of spp1 to granuloma biology in vivo.

Fast väldigt länge sen. Kanske dags att börja om. När jag läste hans första bok (The Search) var jag inte medveten om hur personlig den var, att han lämnade forskningen på grund av en artikel i Nature som visade sig vara inkorrekt.

En grej med långvarig undernäring och svält är att det förstör kroppen på små barn och skapar livslånga men även för dem som överlever.

Congratulations @yichnliu.bsky.social! This is a great moment to launch your #glycotime tools company, we need access to more lectins for glycoprofiling and functional glycomics, and also future therapeutic applications 👏

Så intressant. Tycker att det snarare borde uppfattas som mindre akademiskt. Och användbart.

Kulturdebatt. Bäste Benjamin Dousa, vem har slängt dig under bussen?
Sverker Sörlin frågar i ett öppet brev varför Sveriges biståndsminister har stoppat hjälpen till det svältande och sönderbombade Gaza.
Den här texten av Sverker Sörlin sätter ord på känslan av svek och förvirring som jag också känner. Frustrationen över att inte få ett rakt svar, av att det som sker är både grymt och obegripligt. www.dn.se/kultur/baste...

SA universities face funding crisis as US federal agencies freeze research grants | News24
An investigation into the impact of the US aid freeze on research funding to South African universities has found that 44 programmes worth R2.5 billion were affected.
A not very happy Friday. CERI had 6 NIH grants canceled, which will impact operations, surveillance and response to epidemics. We are working to try to minimize disturbance but not easy with 6 grants terminated at the same moment. A crisis is unfolding in SA www.news24.com/southafrica/...
