Good news for Canadians. More international investment means more of our businesses can scale up faster, creating more high-paying career opportunities for Canadians.

next trainee will be critical to the next significant finding. If we don't aggressively defend this remarkably productive wellspring of knowledge, then we're not worthy custodians or participants in it. We'll have let down those who enabled us to succeed. That's our responsibility, we must own it.

Cross-presentation of dead cell-associated antigens shapes the neoantigenic landscape of tumor immunity - Nature Immunology Here the authors show DNGR-1 expressed by cDC1s promotes CD8⁺ T cell priming to cytoskeletal neoantigens from dying tumor cells, thereby shaping cancer immune visibility and tumor evolution through im...

#WeekendRead! #DendriticCellPower! @reisesousalab.bsky.social @drjonlim.bsky.social &co show @natimmunol.nature.com that cDC1s exploit DNGR1 to crosspresent #tumor #neoantigens derived from F-actin binding proteins protecting against tumorigenesis but favoring cancer immunoediting!

TBK1 and IKKΞ΅ prevent premature cell death by limiting the activity of both RIPK1 and NLRP3 death pathways TBK1 and IKKe prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells.

The loss of TBK1, or both TBK1 and the related kinase IKKΞ΅, results in uncontrolled cell death–driven inflammation. We show that TBK1/IKKΞ΅ prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells. www.science.org/doi/10.1126/...
