|
Adaptive Immunity |
Protection provided by immune responses that mature through life; involves B cells and T cells |
|
|
Antibody |
Y shaped protein that binds antigen |
|
|
Antigen |
Molecule that reacts specifically with either an antibody or an antigen receptor on a lymphocyte |
|
|
Antigen-Presenting Cells (APCs) |
Cells such as B cells, macrophages and dendritic cells that can present exogenous antigens to naive or memory T cells, activating them |
|
|
B cell |
Type of lymphocyte programmed to make antibodies |
|
|
Cell-Mediated Immunity |
Immunity involving a T cell response |
|
|
Clonal Selection |
Process in which a lymphocytes antigen receptor binds to an antigen, allowing the lymphocyte to proliferate |
|
|
Cytotoxic T cell |
Type of lymphocyte programmed to destroy infected or cancerous "self" cells |
|
|
Dendritic cell |
Cell type responsible for activating naive T cells |
|
|
Helper T cell |
Type of lymphocyte programmed to activate B cells and macrophages, and assist other parts of the adaptive immune response |
|
|
Humoral Immunity |
Immunity involving B cells and an antibody response |
|
|
Lymphocytes |
A group of white blood cells (leukocytes) that have antigen-specific receptors on their surface; includes B cells and T cells |
|
|
Major Histocompatibility Complex (MHC) molecules |
Cell surface molecules that present antigen to T cells; includes MHC class I molecules and MHC class II molecules |
|
|
Memory Lymphocytes |
Long-lived descendants of activated lymphocytes that can quickly respond when a specific antigen is encountered again |
|
|
Plasma Cell |
Effector form of a B cell; it functions as an antibody-secreting factory |
|
|
Tc Cell |
Effector form of a cytotoxic T cell; it induces apoptosis in infected or cancerous "self" cells |
|
|
Th Cell |
Effector form of a helper T cell; it activates B cells and macrophages, and releases cytokines that stimulate other parts of the immune system |
