Online Now: DNASE1L3 maintains homeostatic levels of mitochondrial DNA on the mammalian cell surface Online now:

DNASE1L3 maintains homeostatic levels of mitochondrial DNA on the mammalian cell surface
Porat et al. develop cell surface ATAC-See, discovering that mitochondrial DNA is a component of the mammalian cell surface. Cell surface DNA (csDNA) on primary human and murine B cells and monocytes is removed by the secreted nuclease DNASE1L3, and dysregulation of csDNA levels is associated with autoimmunity.

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.

This atlas, when compared to the mRNA-seq from the same cell lines, provides an interesting perspective on the differences one might “learn” from each method applied to the same cells. Surface proteomics, while most complex to accomplish rigorously, was the most revealing for targets for biologics.
