Supplemental Figures 1-10 from Mitochondrial Morphological and Functional Reprogramming Following CD137 (4-1BB) Costimulation

Abstract

<p>Figure S1 shows that CD8 T cells with high mitochondrial transmembrane potential after CD137 stimulation have enlarged mitochondria. Fig S2 shows that CD137 induced mitochondrial changes are not due to enrichment of specific CD8 T cells subsets. Figure S3 shows that mitochondrial enhanced functions induced by CD137 activation are not a consequence of autocrine secretion of cytokines. Fig S4 shows that spare respiratory capacity induced by CD137 activation is dependent on fatty acid oxidation. Figure S5 explores regulation of mitochondrial biogenesis and fusion related genes upon CD137 activation. Fig S6 shows functional effects of OPA knockdown in CD8 T cells. Figure S7 shows the implication of Akt pathway on enhanced mitochondrial function by CD137 activation. Figure S8 shows that CD137KO CD8 T cells have intrinsic mitochondrial defects upon CD28 activation. Figure S9 shows that CD137 activation enhances mitochondrial parameters in tumor infiltrating lymphocytes. Fig S10 shows engrafment abilities and memory markers of OTI cells in B16OVA tumor bearing mice upon OPA silencing and CD137 mAb treatment.</p>
