The TCR Triggering Puzzle [PDF]

Immunity, 2001
Despite extensive efforts, the mechanism of TCR triggering remains poorly understood, and there are a number of competing models. There are major difficulties with more traditional models such as those postulating binding-induced conformational change of the TCR or binding induced-multimerization.

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

Advanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

TCR nanoclusters as the framework for transmission of conformational changes and cooperativity

Frontiers in Immunology, 2012
Increasing evidence favors the notion that, before triggering, the T cell antigen receptor (TCR) forms nanometer-scale oligomers that are called nanoclusters.

Transcript-indexed ATAC-seq for precision immune profiling. [PDF]

, 2018
T cells create vast amounts of diversity in the genes that encode their T cell receptors (TCRs), which enables individual clones to recognize specific peptide-major histocompatibility complex (MHC) ligands. Here we combined sequencing of the TCR-encoding

Recognition of microbial glycolipids by Natural Killer T cells

Frontiers in Immunology, 2015
T cells can recognize microbial antigens when presented by dedicated antigen-presenting molecules. While peptides are presented by classical members of the Major Histocompatibility (MHC) family (MHC I and II), lipids, glycolipids and lipopeptides can be ...

Distinct immune signatures in directly treated and distant tumors result from TLR adjuvants and focal ablation. [PDF]

, 2018
Both adjuvants and focal ablation can alter the local innate immune system and trigger a highly effective systemic response. Our goal is to determine the impact of these treatments on directly treated and distant disease and the mechanisms for the ...

IL‐2 Free Expansion of T Cells with Immunofilaments

Advanced Healthcare Materials, EarlyView.
Ratio and density of stimulatory αCD3 and αCD28 mAb on immunofilaments (IF) influence T cell expansion, cytokine production, and effector phenotype. Moreover, IL‐2 supplementation is not necessary with optimal performing IFs, which leads to simpler culture conditions, and negative side effects of IL‐2 supplementation are reduced.

Safety and efficacy of Tet-regulated IL-12 expression in cancer-specific T cells

OncoImmunology, 2019
We explored whether engineering of T cell specificity and effector function improves immunotherapy of solid tumors. Although IL-12 can enhance cancer immunity, a strategy of safe IL-12 delivery without toxicity is currently lacking. We engineered T cells

Tunable Enhancement of T Cell Expansion Through Modulation of Stiffness and Adhesion Receptor Engagement in an Engineered Hydrogel Platform

Advanced Materials, EarlyView.
We develop a hydrogel scaffold with controlled substrate stiffness and ligand functionalization for cell culture. Stiff substrates presenting CD3/CD28/CD2 ligands induce 2000‐fold expansion of T cells; this is 68% greater than the clinical standard (Dynabeads) and the first hydrogel capable of large‐scale expansion. Although expanding at a lower yield,
