Organs and Cells of The Immune System Part 1
Lymph containing lymphocytes, antigen, and soluble mediators drains from surrounding tissues and enters the lymph nodes via afferent lymphatic vessels. The lymph node consists of a cortex and a medulla. The outermost area of the cortex has B cells organized into lymphoid follicles, and its deep, or paracortical, area consists mainly of T cells and dendritic cells. After B cells encounter antigens for which they have receptors, along with the appropriate T cells, central areas of marked B cel...
Non-Small Cell Lung Cancer Treatment
Immune checkpoint inhibitor; the panel on the left shows the binding of proteins PD-L1 (on the tumor cell) to PD-1 (on the T cell), which keeps T cells from killing tumor cells in the body. Also shown are a tumor cell antigen and T cell receptor. The panel on the right shows immune checkpoint inhibitors (anti-PD-L1 and anti-PD-1) blocking the binding of PD-L1 to PD-1, which allows the T cells to kill tumor cells.

Differences Between B-Cells and T-Cells
Differences Between B-Cells and T-Cells. T cells and B cells are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity.
