Glycosylation-driven programs coordinate immunoregulatory and pro-angiogenic functions of myeloid-derived suppressor cells Blidner et al. identify a glycosylation-dependent, galectin-driven circuit as a common mechanism that simultaneously induces immunosuppressive and pro-angiogenic functions in myeloid-derived suppresso...

The Rabinovichlab discovered that MDSC-specific deletion of ST6Gal1 enhanced GAL1-driven suppressive signals and accelerated tumor growth, effects that can be ameliorated by GAL1-blocking antibodies www.cell.com/immunity/ful...

Opinion | The White House Tech Bros Owe Their Fortunes to the Research They’re Killing Underlying many investments are breakthroughs in medicine and technology from great universities.

“Given the very real consequences for our competitiveness, our standard of living and, yes, also our bottom lines, we all ought to be making the case for aggressively funding basic science.”

NIH cuts billions of dollars in biomedical funding, effective immediately The move halts a large slice of money for most universities and research institutions virtually overnight, imperiling vital research in everything from cancer to heart disease.

Another assault on US competitiveness at a time when biomedicine is roaring with innovation, an own-goal in a high-stakes international tournament. Of course the real losers are American people needing medicines and cures.
