Adaptive Immune Response

what cells are involved in cellular immunity

T cells

what does cellular immunity defend against

viral and fungal infections

what type of reaction is involved with cellular immunity

delayed hypersensitivity reaction

provides regulation of antibody response

cellular immunity

what cells are involved in humoral immunity

B cells and plasma cells

how does humoral immunity defend

opsonizes bacteria

what type of response is a result of humoral immunity

allergic reaction

what are the 2 types of immunity in the adaptive immune responses

cellular and humoral

which part of the adaptive immune response allows for autoimmunity

humoral immunity

arise in bone marrow and mature in the thymus

T cells

secrete low molecular weight cytokine proteins that have a regulatory function

T helper cells

what do T helper cells activate to produce antibodies

B cells

kill virus infected cells and sometimes tumor infected cells

T cytotoxic cells

play a role in immune tolerance

T suppressor cells

may show a link between innate and acquired immune responses

natural killer T cells

main player in humoral immunity

B cells

remember pathogens for faster antibody production

B memory cells

what type of cell are B cells

antigen presenting cells

what can B cells differentiate into

plasma cells that make antibodies

what is the structure of antibodies from B cells

disulfide bonds that bind chains

only antibody to cross the placental barrier

IgG

first antibody to the site and the largest

IgM

antibody involved with allergies, and binds to mast cells

IgE

ride or die antibody, releases B lymphocytes

IgD

antibody found in saliva

IgA

key antigen presenting cell

dendritic cell

where are dendritic cells found

between internal and external environments

what do dendritic cells initiate

immune responses

what do dendritic cells regulate

adaptive immune responses
