Adaptive Immunity

adaptive (specific) immunity

type of immunity when clonal lines respond to specific antigens

whether things in our body are invaders and need to be destroyed

What does it mean for the body to identify self from non-self?

B cells and T cells

What 2 cells are key to specific immunity?

specificity, versatility, immunologic memory, and tolerance

What are 4 properties of adaptive immunity?

how they recognize antigens

Although B cells and T cells both respond to antigens, what is different about them?

invaders outside the cells

What do B cells attack?

infected cells

What do T cells attack?

antibodies

unlike T cells, B cells produce…

plasma cells

What are the final active form of B cells?

T cells

What cells make up 70-80% of circulating lymphocytes?

major histocompatibility complex

What is the antigen called that presents antigens to T cells?

cytotoxic T cells

T cells involved in only cell-mediated response

helper T cells

T cells involved in both cell-mediated and antibody-mediated response

cytokines (interleukins)

What do helper T cells release to help boost immune response?

cancerous or virally infected cells

What types of cells do cytotoxic T cells destroy?

helper T cells

What cells aid in B cell response?

memory cells and plasma cells

What are the 2 types of B cells

activation and proliferation of B cells

What are the 2 things that the humoral response requires?

because there is a build up of memory cells

Why are secondary responses faster?

a memory cell

What is considered an activated cell?
