B cell (B lymphocyte)
Lymphocyte that matures into a plasma cell to secrete antibodies
Cell mediated immunity
T cells respond to antigens and kill them;A type of adaptive immunity
Complement system
Set of protiens in the blood that help antibodies kill their target
Cytokines
Proteins secreted by cytotoxic T cells to aid in antigen destruction
Cytotoxic T cell
Lymphocyte that directly kills antigens
- CD8+ T cell
Dendritic cell
Antigen presenting cell. Shows T&B cells what to attack
Helper T cell
Lymphocyte that aids B cells and stimulates T cells
- CD4+ T cell
Humoral immunity
B cells produce antibodies after exposure to specific antigens; type of adaptive immunity
Immunity
Body’s ability to resist foreign organisms and toxins that damage tissue and organs
Immunoglobins
Antibodies such as IgA, IgE, Etc; secreted by plasma cells in response to the presence of an antigen
Interferons
Proteins(cytokines) secreted by T cells and other cells to aid and regulate the immune response
Interleukins
Proteins (cytokines) that stimulate the growth of B and T lymphocytes
