Actin cytoskeletal dynamics in T lymphocyte activation and migration.
Dynamic rearrangements of the actin cytoskeleton are crucial for the function of numerous cellular elements including T lymphocytes. They are required for migration of T lymphocytes through the body to scan for the presence of antigens, as well as for the formation and stabilization of the immunological synapse at the interface between antigen-presenting cells and T lymphocytes. Supramolecular ...
متن کاملThe Actin Cytoskeleton and Lymphocyte Activation
" organized contacts " at the interfaces of physical contact between T cells and APCs (Monks et al., 1997). areas between T cells and APCs incubated with anti-genic peptides indicate that a SMAC is organized into Stanford, California 941010-0269 distinct spatial domains (Monks et al., 1998). The central area of a SMAC contains the TCR, CD3, p56 lck and p59 fyn kinases, and protein kinase C (PKC...
متن کاملCEACAM1 dynamics during neisseria gonorrhoeae suppression of CD4+ T lymphocyte activation.
Neisseria gonorrhoeae colony opacity-associated (Opa) proteins bind to human carcinoembryonic antigen cellular adhesion molecules (CEACAM) found on host cells including T lymphocytes. Opa binding to CEACAM1 suppresses the activation of CD4(+) T cells in response to a variety of stimuli. In this study, we use primary human CD4(+) T cells isolated from peripheral blood to define the molecular eve...
متن کاملVisualizing lipid raft dynamics and early signaling events during antigen receptor-mediated B-lymphocyte activation.
Recent biochemical evidence indicates that an early event in signal transduction by the B-cell antigen receptor (BCR) is its translocation to specialized membrane subdomains known as lipid rafts. We have taken a microscopic approach to image lipid rafts and early events associated with BCR signal transduction. Lipid rafts were visualized on primary splenic B lymphocytes from wild-type or anti-h...
متن کاملB and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation
Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...
