Abstract
Binding of the T cell receptor complex to its ligand, the subsequent molecular rearrangement, and the concomitant cell-scale shape changes represent the very first steps of adaptive immune recognition. The first minutes of the interaction of T cells and antigen presenting cells have been extensively scrutinized; yet, gaps remain in our understanding of how the biophysical properties of the environment may impact the sequence of events. In particular, many pioneering experiments were done on immobilized ligands and gave major insights into the process of T cell activation, whereas later experiments have indicated that ligand mobility was of paramount importance, especially to enable the formation of T cell receptor clusters. Systematic experiments to compare and reconcile the two schools are still lacking. Furthermore, recent investigations using compliant substrates have elucidated other intriguing aspects of T cell mechanics. Here we review experiments on interaction of T cells with planar artificial antigen presenting cells to explore the impact of mechanics on adhesion and actin morphodynamics during the spreading process. We enumerate a sequence tracing first contact to final spread state that is consistent with current understanding. Finally, we interpret the presented experimental results in light of a mechanical model that captures all the different morphodynamic states.

Abstract
T cell receptor (TCR) clustering and formation of an immune synapse are crucial for TCR signaling. However, limited information is available about these dynamic assemblies and their connection to transmembrane signaling. In this work, TCR clustering is controlled via plug-and-play nanotools based on an engineered irreversible conjugation pair and a peptide-loaded major histocompatibility complex (pMHC) molecule to compare receptor assembly in a ligand (pMHC)-induced or ligand-independent manner. A streptavidin-binding peptide displayed in both tools enabled their anchoring in streptavidin-pre-structured matrices. Strikingly, pMHC-induced clustering in the confined regions exhibit higher density and dynamics than the ligand-free approach, indicating that the size and architecture of the pMHC ligand influences TCR assembly. This approach enables the control of membrane receptor clustering with high specificity and provides the possibility to explore different modalities of receptor activation.

Abstract
Cell-surface receptors mediate communication between cells and their environment. Lateral membrane organization and dynamic receptor cluster formation are fundamental in signal transduction and cell signaling. However, it is not yet fully understood how receptor clustering modulates a wide variety of physiologically relevant processes. Recent growing evidence indicates that biological responses triggered by membrane receptors can be modulated even in the absence of the natural receptor ligand. We review the most recent findings on how ligand-independent receptor clustering can regulate transmembrane signaling. We discuss the latest technologies to control receptor assembly, such as DNA nanotechnology, optogenetics, and optochemistry, focusing on the biological relevance and unraveling of ligand-independent signaling.

Abstract
Membrane receptor clustering is fundamental to cell-cell communication; however, the physiological function of receptor clustering in cell signaling remains enigmatic. Here, we developed a dynamic platform to induce cluster formation of neuropeptide Y2 hormone receptors (Y2R) in situ by a chelator nanotool. The multivalent interaction enabled a dynamic exchange of histidine-tagged Y2R within the clusters. Fast Y2R enrichment in clustered areas triggered ligand-independent signaling as determined by an increase in cytosolic calcium and cell migration. Notably, the calcium and motility response to ligand-induced activation was amplified in preclustered cells, suggesting a key role of receptor clustering in sensitizing the dose response to lower ligand concentrations. Ligand-independent versus ligand-induced signaling differed in the binding of arrestin-3 as a downstream effector, which was recruited to the clusters only in the presence of the ligand. This approach allows in situ receptor clustering, raising the possibility to explore different receptor activation modalities.

Abstract
Designing intelligent molecules and smart nanomaterials as molecular machines is becoming increasingly important in the nanoscience fields. Herein, we report a nanodot actuator with changeable fluorescence by π-π stacking force based on a four-armed foldable phthalocyanine molecule. The assembled nanodot possessed a three-dimensional molecular space structure and multiple supramolecular interactions. The arms of the nanodot could fold and open intelligently in response to environmental molecular stimuli such as natural plant mimosa, which could lead to multiple variable fluorescence emissions. The nanodot was highly sensitive to the biomolecule thyroxine at the molecular level. The accurate molecular recognition and the changeable fluorescence conversion of the nanodot were attributed to multiple supramolecular interactions, including photoinduced electron transfer (PET), intramolecular fluorescence resonance energy transfer (FRET), and π-π stacking of the nanodots, resulting in an intelligent "nanodot machine with folding arms". The self-assembled nanodot actuators with changeable fluorescence have potential applications in advanced intelligent material fields.

Abstract
The spatiotemporal aspects of early signaling events during interactions between cells and their environment dictate multiple downstream outcomes. While advances in nanopatterning techniques have allowed the isolation of these signaling events, a major limitation of conventional nanopatterning methods is its dependence on gold (Au) or related materials that plasmonically quench fluorescence and, thus, are incompatible with super-resolution fluorescence microscopy. Here we describe a novel method that integrates nanopatterning with single-molecule resolution fluorescence imaging, thus enabling mechanistic dissection of molecular-scale signaling events in conjunction with nanoscale geometry manipulation. Our method exploits nanofabricated titanium (Ti) whose oxide (TiO2) is a dielectric material with no plasmonic effects. We describe the surface chemistry for decorating specific ligands such as cyclo-RGD (arginine, glycine and aspartate: a ligand for fibronectin-binding integrins) on TiO2 nanoline and nanodot substrates, and demonstrate the ability to perform dual-color super-resolution imaging on these patterns. Ti nanofabrication is similar to other metallic materials like Au, while the functionalization of TiO2 is relatively fast, safe, economical, easy to set up with commonly available reagents, and robust against environmental parameters such as humidity. Fabrication of nanopatterns takes ~2-3 d, preparation for functionalization ~1.5-2 d, and functionalization 3 h, after which cell culture and imaging experiments can be performed. We suggest that this method may facilitate the interrogation of nanoscale geometry and force at single-molecule resolution, and should find ready applications in early detection and interpretation of physiochemical signaling events at the cell membrane in the fields of cell biology, immunology, regenerative medicine, and related fields.

Abstract
Activation of T-cell proliferation specifically in a tumor is crucial for reducing the autoimmune side effects of antitumor immunotherapy. Herein, we developed a pH-driven interlocked DNA nano-spring (iDNS) to stimulate T-cell activation in vivo in response to the low pH value in a tumor microenvironment. The interlocked structure of iDNS provide a more rigid scaffold in comparison to double-stranded DNA for ligand assembly, which can help to control the spatial distribution of ligands with more accuracy. We have demonstrated that the pH-driven reversible reconfiguration of iDNS provides a powerful way to regulate the nanoscale distribution of T-cell receptors (CD3) on the cell surface. The relatively low pH value (pH 6.5) in a solid tumor was able to drive the springlike shrinking of iDNS and induce significant T-cell proliferation, leading to an enhanced antitumor effect, thus providing a tool for specifically inducing an immune response in a tumor for immunotherapy.
