plasma cells

Biology; Immunology

Plasma cells are terminally differentiated B lymphocytes and are the main antibody-secreting cells of the body. They are found in the medulla of the lymph nodes, in splenic red ...

linkage disequilibrium

Biology; Immunology

c-Kit

Biology; Immunology

The cell-surface receptor c-Kit, present on developing B cells and other developing white blood cells, binds to the stem cell factor on bone marrow stromal cells. Kit has protein ...

terminal complement components,

Biology; Immunology
