Great work out of the Morrissey lab! In our early 2D phagocytosis time lapses, we could only really see "whole cell eating" when cells were splitting from one another so the mitotic vulnerability makes sense.
@kirstin-rollins.bsky.social, @mmorrissey.bsky.social et al show that #macrophages attack adherent cells using #trogocytosis instead of #phagocytosis. Reducing adhesion increased phagocytosis. Mitotic cells, which disassemble adhesions, are more vulnerable to phagocytosis rupress.org/jcb/article/...

Nerve-to-cancer transfer of mitochondria during cancer metastasis - Nature
A study reports the development of a method to trace intercellular transfer of mitochondria, and demonstrates that cancer cells that receive mitochondria from neurons have enhanced metastatic capabilities.

🚨RED ALERT for 🧪:

The Trump NIH just gashed indirect costs. This is a direct attack on universities.

“Pursuant to this Supplemental Guidance, there will be a standard rate of 15% across all NIH grants for indirect costs.” 😮

Just a devastating Friday night news dump. #scicomm #academicaky

A new mechanism for cancer-induced immune evasion. We knew about cancer cells hijacking mitochondria. Now we learn about how their mitochondrial transfer to T cells impairs the tumor immune response.

While I won't be at #CellBio2024 this year, several folks in the Roh-Johnson lab will be presenting interesting data from all facets of the lab: Focal adhesions (Julio Fierro, Kara Jones), Macrophage Polarization (Sophia Varady), and Chimeric antigen receptor macrophages (Minna herself!) Go say hi!

This thread is about HUMAN IMMUNE SYSTEM

Its primary function is to defend the body from pathogens, which are disease-causing organisms such as viruses and bacteria. Tissues, cells, and proteins in the immune system work together to achieve this function. @jama.com

Grant agency: "In the end, despite some initial enthusiasm, the panel was not convinced [...], and expected that the impact in the field is likely to be low."
Despite evidence to the contrary, funding bodies remain confident they can predict the success of a project.
