Nаïve B аnd T cells аre recruited tо lymph nоdes fоr they express the chemokine receptor [blank1] while high endothelial cells (HEVs) produce the chemokine [blank2]. Once into the lymph node, B cells further migrate to the B cell zones due to their expression of another chemokine receptor [blank3]. After encounters with antigens in secondary lymphoid organs, some B cells form the primary focus, where they first differentiate into antibody-synthesizing [blank4] that are still dividing. Eventually, the antibody-secreting, long-lived [blank5] emerge. Other B cells migrate back into the B-cell zone and establish the germinal center. The germinal center contains a dark zone and a light zone. In the dark zone, B cells are called [blank6] and they are highly proliferative. B cells that enter the dark zone express chemokine receptor [blank7] in addition to [blank3]. In the light zone, B cells slow down proliferation and are called [blank8]. Here, B cells with high-affinity BCRs will capture antigens trapped on the surface of [blank9] cells and process and present the antigenic peptides to [blank10] cells for their help. Help provided by [blank10] cells includes affinity maturation and class switch. Class switch confers more effector mechanisms to immunoglobulins. For example, the dimeric form of [blank11] is found in secretions such as breast milk, while [blank12] is mostly associated with mast cells underneath the epithelium.
