abstract = {The cell-autonomous balance of immune-inhibitory and
-stimulatory signals is a critical process in cancer immune
evasion. Using patient-derived co-cultures, humanized mouse
models, and single-cell RNA-sequencing of patient melanomas
biopsied before and on immune checkpoint blockade, we find
that intact cancer cell-intrinsic expression of CD58 and
ligation to CD2 is required for anti-tumor immunity and is
predictive of treatment response. Defects in this axis
promote immune evasion through diminished T cell activation,
impaired intratumoral T cell infiltration and proliferation,
and concurrently increased PD-L1 protein stabilization.
Through CRISPR-Cas9 and proteomics screens, we identify and
validate CMTM6 as critical for CD58 stability and
upregulation of PD-L1 upon CD58 loss. Competition between
CD58 and PD-L1 for CMTM6 binding determines their rate of
endosomal recycling over lysosomal degradation. Overall, we
describe an underappreciated yet critical axis of cancer
immunity and provide a molecular basis for how cancer cells
balance immune inhibitory and stimulatory cues.},
