T-cell receptor signaling actively regulates gating of the nuclear pore complex (NPC) in T cells by inducing translocation of protein kinase C-θ to the NPC to promote the sumoylation of RanGAP1.
A high-throughput technique to characterize the substrate specificities of tyrosine kinases identifies the key features of kinases and substrates that enforce accurate signaling from T cell receptors.

Controlling the duration of ligand binding to the T cell receptor by light shows that T cells discriminate stimulatory from non-stimulatory ligands by measuring the dynamics of ligand binding.
The strength of TCR signalling determines the rate at which cells initiate a tightly coordinated signalling programme, without altering its organization.

The immunoglobulin E (IgE) B cell receptor promotes plasma cell differentiation in the absence of cognate antigen and limits the competitive fitness of IgE+ B cells in germinal centers.
Antagonistic signaling by the kinases PI3K and Itpkb limits the kinetics and enforces the Notch-dependence of beta-selection – the most important cell-fate determining process in alpha beta T cell development.
Sorting nexin 9, a membrane curvature inducing protein, creates a distinct environment within clusters of the co-receptor CD28 and thereby allows T cell activation to proceed to a successful outcome.
Non-specific sodium entry inhibits T cell receptor induced gene expression and differentiation of T cells by depleting intracellular ATP and disrupting mTORC2 dependent signalling axis.
