Supplementary Data from MERTK Acts as a Costimulatory Receptor on Human CD8⁺ T Cells

Abstract

<p>Supplementary Methods. Table S1: primer sequences. Figure S1: PROS1 and MERTK co-expression on 3-day activated CD8+ T cells. Figure S2: TAM receptors TYRO3 and AXL are nearly absent or absent on CD8+ T cells. Figure S3: Phosphatidylserine is not a limiting factor for TAM signaling in CD8+ T cell cultures and is partly non-apoptotic. Figure S4: Bioenergetic properties of PROS1-supplemented cells. Figure S5: PROS1 consumption by cancer cells and T cells affects TIL-mediated killing.</p>
