Abstract
Cell-based immunotherapies, such as T cells engineered with chimeric antigen receptors (CARs), have the potential to cure patients of disease otherwise refractory to conventional treatments. Early-on-treatment and long-term durability of patient responses depend critically on the ability to control the potency of adoptively transferred T cells, as overactivation can lead to complications like cytokine release syndrome, and immunosuppression can result in ineffective responses to therapy. Drugs or biologics (e.g., cytokines) that modulate immune activity are limited by mass transport barriers that reduce the local effective drug concentration, and lack site or target cell specificity that results in toxicity. Emerging technologies that enable site-targeted, remote control of key T cell functions - including proliferation, antigen-sensing, and target-cell killing - have the potential to increase treatment precision and safety profile. These technologies are broadly applicable to other immune cells to expand immune cell therapies across many cancers and diseases. In this review, we highlight the opportunities, challenges and the current state-of-the-art for remote control of synthetic immunity.

Abstract
![]()
Activation
of a cytotoxic T-cell is a complex multistep process,
and tools to study the molecular events and their dynamics that result
in T-cell activation in situ and in vivo are scarce. Here, we report the design and use of conditional epitopes
for time-controlled T-cell activation in vivo. We
show that trans-cyclooctene-protected SIINFEKL (with
the lysine amine masked) is unable to elicit the T-cell response characteristic
for the free SIINFEKL epitope. Epitope uncaging by means of an inverse-electron
demand Diels–Alder (IEDDA) event restored T-cell activation
and provided temporal control of T-cell proliferation in vivo.

Abstract
We report the chemical synthesis of the first photo-activatable protein antigen that can be used to study antigen-antibody interaction mediated responses in B cells. This strategy facilitated fine tuning of the caged protein antigen to optimize its bioactivity and photochemical properties. One optimal molecule, HEL-K96NPE, was totally inert to hen egg lysozyme (HEL)-specific B cells and could only restore its antigenicity upon photoactivation. Combined with real time live cell imaging, the utility of HEL-K96NPE was demonstrated as a proof of concept to quantify B cell synapse formation and calcium influx responses at the single cell level.

Abstract
The activation of CD8(+) T-cells requires the uptake of exogenous polypeptide antigens and proteolytic processing of these antigens to octamer or nonamer peptides, which are loaded on MHC-I complexes and presented to the T-cell. By using an azide as a bioorthogonal protecting group rather than as a ligation handle, masked antigens were generated-antigens that are not recognized by their cognate T-cell unless they are deprotected on the cell using a Staudinger reduction.
