Lymphoid Lineage

The lymphoid lineage refers to a group of immune cells that develop from common stem cells in the bone marrow. These cells include lymphocytes such as T cells, B cells, and natural killer (NK) cells, which are essential for protecting the body against infections and cancer. T cells mature in the thymus, B cells in the bone marrow, and NK cells develop in the same way as other lymphocytes. Together, these cells coordinate immune responses, identify harmful invaders, and remember past infections to provide long-term immunity. The lymphoid lineage is a vital part of the body's immune defense system.
