The natural peptide-major histocompatibility complex (pMHC) ligand for T cell receptors (TCRs) is inactive from solution yet capable of activating T cells at single-molecule levels when membrane-associated. This distinctive feature stems from the mec

Significance Immune cells in the body encounter stimuli in complex temporal patterns, but our understanding of how the timing of stimulation determines immune responses is incomplete. We engineered T cells obtained from healthy human donors to respon

T cells discriminate between self and foreign antigenic peptides, displayed on antigen presenting cell surfaces, via the TCR. While the molecular interactions between TCR and its ligands are well characterized in vitro, quantitative measurements of t

Significance Antigen discrimination by T cells is based on subtle differences in binding of the T cell receptor (TCR) for its peptide major histocompatibility complex (pMHC) ligand. While such binding characteristics are readily mapped with great pre

Here we introduce a form of chromatography that can be imposed on the membrane of a living cell. A cell–cell signaling interaction is reconstituted in a hybrid live cell-supported membrane junction. The chromatographic material consists of a hexago

The galectin family of glycan-binding proteins is thought to mediate many cellular processes by oligomerizing cell surface glycoproteins and glycolipids into higher-order aggregates. This hypothesis reflects the known oligomeric states of the galecti

We present a supported membrane platform consisting of a fluid lipid bilayer membrane embedded with a fixed array of gold nanoparticles. The system is realized by preforming a hexagonal array of gold nanoparticles (∼5–7 nm) with controlled spacin

We demonstrate that the gauche conformation of 1H-nonafluorobutane contains a blue-shifting intramolecular hydrogen bond by recording its 5th overtone spectrum with cavity ringdown spectroscopy and performing electronic structure calculations. The ma
