B cells acquire antigen from target cells after synapse formation

Article Abstract:

Research is presented describing how B cell interaction with antigens immobilized on a target cell surface, leads to a synapse being formed, and antigens being acquired from the target. This will enhance B cell activation at low-antigen concentration, enhance B- and T-cell epitope links, and enable antigen recognition.

Visualizing the generation of memory CD4 T cells in the whole body

Article Abstract:

Research is presented concerning the use of immunohistology to specify and enumerate individual naive CD4 T cells in the entire bodies of mice. The recognition of antigens and generation of memory cells is discussed.

Memory needs no reminders

Article Abstract:

Issues are presented concerning the ability of the immune system to 'remember' diseases which affected the body and to protect it from reinfection at a later date. The process behind immune memory is discussed.
