The ciliary machinery is repurposed for T cell immune synapse trafficking of LCK [PDF]
, 2018 Upon engagement of the T cell receptor with an antigen-presenting cell, LCK initiates TCR signaling by phosphorylating its activation motifs. However, the mechanism of LCK activation specifically at the immune synapse is a major question.

The immune synapses reveal aberrant functions of CD8 T cells during chronic HIV infection
Nature Communications, 2022 HIV infection over time is thought to result in premature aging and aberrant immune responses including the induction of immunological senescence. Here the authors show altered formation of immune synapses by naive CD8+ T cells and dysregulated synapse ...

Stochastic model of T Cell repolarization during target elimination (I) [PDF]
, 2020 Cytotoxic T lymphocytes (T) and natural killer (NK) cells are the main cytotoxic killer cells of the human body to eliminate pathogen-infected or tumorigenic cells (i.e. target cells). Once a NK or T cell has identified a target cell, they form a tight contact zone, the immunological synapse (IS).

Spatial Organization of the Cytoskeleton enhances Cargo Delivery to Specific Target Areas on the Plasma Membrane of Spherical Cells [PDF]
, 2016 Intracellular transport is vital for the proper functioning and survival of a cell. Cargo (proteins, vesicles, organelles, etc.) is transferred from its place of creation to its target locations via molecular motor assisted transport along cytoskeletal ...

Mechanisms of B cell Synapse Formation Predicted by Stochastic Simulation [PDF]
, 2006 The clustering of B cell receptor (BCR) molecules and the formation of the protein segregation structure known as the immunological synapse appears to precede antigen (Ag) uptake by B cells. The mature B cell synapse is characterized by a central cluster of BCR/Ag molecular complexes surrounded by a ring of LFA-1/ICAM-1 complexes.

Deterministic mechanical model of T-killer cell polarization reproduces the wandering of aim between simultaneously engaged targets [PDF]
, 2009 T-killer cells of the immune system eliminate virus-infected and tumorous cells through direct cell-cell interactions. Reorientation of the killing apparatus inside the T cell to the T-cell interface with the target cell ensures specificity of the immune

The Roles of Membrane Rafts in CD32A-Mediated Phagocytosis [PDF]
, 2007 Membrane rafts are highly dynamic heterogeneous sterol- and sphingolipid-rich micro-domains on cell surfaces. They are generally believed to provide residency for cell surface molecules (e.g., adhesion and signaling molecules) and scaffolding to ...

Temporal dynamics in immunological synapse: Role of thermal fluctuations in signaling [PDF]
, 2016 The article analyzes the contribution of stochastic thermal fluctuations in the attachment times of the immature T-cell receptor TCR: peptide-major-histocompatibility-complex pMHC immunological synapse bond. The key question addressed here is the following: how does a synapse bond remain stabilized in the presence of high frequency thermal noise that ...
