MAIT cells come to the rescue in cancer immunotherapy? [PDF]
Recent progress in immunobiology has led to the observation that, among cells classically categorized as the typical representatives of the adaptive immune system, i.e., T cells, some possess the phenotype of innate cells.

While normal B- and T-lymphocytes require antigenic ligands to become activated via their B- and T-cell receptors (BCR and TCR, respectively), B- and T-cell lymphomas show the broad spectrum of cell activation mechanisms regarding their dependence on BCR

B cell activation involves nanoscale receptor reorganizations and inside-out signaling by Syk
Binding of antigen to the B cell antigen receptor (BCR) initiates a multitude of events resulting in B cell activation. How the BCR becomes signaling-competent upon antigen binding is still a matter of controversy.

Expression of DC-SIGN and DC-SIGNR on human sinusoidal endothelium: a role for capturing hepatitis C virus particles. [PDF]
Hepatic sinusoidal endothelial cells are unique among endothelial cells in their ability to internalize and process a diverse range of antigens. DC-SIGNR, a type 2 C-type lectin expressed on liver sinusoids, has been shown to bind with high affinity to ...

Molecular Mechanisms Used by Salmonella to Evade the Immune System [PDF]
Human and animal pathogens are able to circumvent, at least temporarily, the sophisticated immune defenses of their hosts. Several serovars of the Gram-negative bacterium Salmonella enterica have been used as models for the study of pathogen-host ...

Distinct Roles for Bruton's Tyrosine Kinase in B Cell Immune Synapse Formation
Bruton's tyrosine kinase (Btk) has a key role in the signaling pathways of receptors essential for the B lymphocyte response. Given its implication in B cell-related immunodeficiencies, leukemias/lymphomas and autoimmunity, Btk is studied intensely and ...

Expression of interleukin 2 receptors on activated human B cells. [PDF]
Using anti-Tac, a monoclonal anti-interleukin 2 (IL-2) receptor antibody, we have explored the possibility that certain activated B cells display receptors for IL-2.

Co-receptor CD8-mediated modulation of T-cell receptor functional sensitivity and epitope recognition degeneracy [PDF]
The interaction between T-cell receptors (TCRs) and peptide epitopes is highly degenerate: a TCR is capable of interacting productively with a wide range of different peptide ligands, involving not only cross-reactivity proper (similar epitopes elicit ...

The B cell antigen receptor in B-cell development
During B-cell development, immature and mature forms of the B cell antigen receptor complex are deployed in a regulated fashion; thus, B cell antigen receptor complexes play essential roles in the transit of cells through ontogeny. The past year has seen progress in our understanding of how antigen receptor gene assembly is controlled and in defining ...
