Immune evasion through mitochondrial transfer in the tumour microenvironment - Nature Mitochondria with mutations in their DNA from cancer cells can be transferred to T cells in the tumour microenvironment, which leads to T cell dysfunction and impaired antitumour immunity.

I am just reading this paper, and it is absolutely wild. Tumor cells acquire mutations in mitochondria, and then transfer them to T-cells, and the mutant mitochondria drives dysfunction in the T-cells?! www.nature.com/articles/s41...

Tumour-reactive heterotypic CD8 T cell clusters from clinical samples Tumour-reactive CD8+ T cells are enriched in functional clusters with tumour cells and/or antigen-presenting cells and can be isolated and expanded from clinical samples.

As the saying goes, one man’s trash is another man’s treasure: the flow-cytometry doublets that are routinely excluded from analysis are in fact a rich source of tumor-reactive T cells.

Thanks, will try it ! We use cells for unstained/autofluorescence and viability, for the other markers we use beads

Thanks a lot for the informative thread! Looks very exciting

Are single stained cellular controls necessary or only better ? We are using rare human samples so it's difficult to cells for single color controls, can we still hope to see improvements with AutoSpectral unmixing ?

Pre-print alert! And this one really is a must read for anyone that does spectral #flowcytometry. It is a complete, fully-automated spectral unmixing pipeline that reduces error up to 9000-fold.

One mother for two species via obligate cross-species cloning in ants - Nature In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same mother having distinct genomes and morphologies.

Unbelievable news.

Pancreatic is one of the deadliest cancers.

New paper shows personalized mRNA vaccines can induce durable T cells that attack pancreatic cancer, with 75% of patients cancer free at three years—far, far better than standard of care.
