How do plasma cells form, and how do they fight pathogens?

• Adaptive immunity depends on two types of lymphocytes that recognize and respond to specific invading pathogens.

• Like all blood cells, lymphocytes originate from stem cells in the bone marrow.

B cells fully develop and become specialized in the bone marrow.

Immature T cells migrate via the blood to the thymus, a gland in the chest, where they mature and become specialized.

Both B cells and T cells eventually make their way to the lymph nodes and other lymphatic organs and wait to encounter an invader.
