The case for absolute ligand discrimination : modeling information processing and decision by immune T cells [PDF]
Some cells have to take decision based on the quality of surroundings ligands, almost irrespective of their quantity, a problem we name "absolute discrimination". An example of absolute discrimination is recognition of not-self by immune T Cells. We show

Memory control by the B cell antigen receptor
SummaryThe generation of memory B cells (MBCs) that have undergone immunoglobulin class switching from IgM, which dominates primary antibody responses, to other immunoglobulin isoforms is a hallmark of immune memory. Hence, humoral immunological memory is characterized by the presence of serum immunoglobulins of IgG subtypes known as the γ‐globulin ...

Activation of the Rap1 GTPase by the B Cell Antigen Receptor [PDF]
The B cell antigen receptor (BCR) activates Ras, a GTPase that promotes cell proliferation by activating the Raf-1/MEK/ERK signaling module and other signaling enzymes. In its active GTP-bound form, the Rap1 GTPase may act as a negative regulator of Ras-mediated signaling by sequestering Ras effectors (e.g., Raf-1) and preventing their activation.

The second touch hypothesis states that T cell activation, proliferation, induction of homing receptors and polarization are distinguishable and, at least in part, sequential. The second touch hypothesis maintains that full T cell polarization requires T

Summary: This protocol describes how to identify Dual Expressers (DEs), a rare type of lymphocyte that co-expresses B-cell receptors and T-cell receptors, by flow cytometry using a cocktail of four antibodies. It also shows the subsequent gating strategy

Resting and activated states of the B cell antigen receptor [PDF]
Each B cell contains up to 100,000 B cell antigen receptor (BCR) complexes on its surface, which only become fully active on exposure of the B cell to its cognate antigen. Most studies on BCR function aims at a better understanding how the BCR becomes active and transmits its signal to the many signaling pathways inside the cell.

Chronic lymphocytic leukemia B cells express auto/xeno antigen-reactive antibodies that bind to self-epitopes and resemble natural IgM antibodies in their repertoire.

Functional diversity of chemokines and chemokine receptors in response to viral infection of the central nervous system. [PDF]
Encounters with neurotropic viruses result in varied outcomes ranging from encephalitis, paralytic poliomyelitis or other serious consequences to relatively benign infection.

Nanobody based dual specific CARs [PDF]
Recent clinical trials have shown that adoptive chimeric antigen receptor (CAR) T cell therapy is a very potent and possibly curative option in the treatment of B cell leukemias and lymphomas.
