Card preview (10)

#1
Front (Question)

what cells are involved in the cell mediated response?

Back (Answer)

T cells

#2
Front (Question)

briefly describe what happens in the cell mediated response

Back (Answer)

• receptors on T cells bind to antigens on antigen presenting cells • T cells divide rapidly by mitosis (clonal expansion)

#3
Front (Question)

state 4 examples of antigen presenting cells

Back (Answer)

• infected body cells with viral antigens • macrophages which have engulfed and destroyed a pathogen • transplanted organ cells • cancer cells with abnormal shaped antigens

#4
Front (Question)

stage 1 (APC)

Back (Answer)

after being engulfed and destroyed in phagocytosis, the cell is antigen presenting

#5
Front (Question)

stage 2 (receptors)

Back (Answer)

T helper cells receptors attach to antigens of APCs

#6
Front (Question)

stage 3 (interleukins)

Back (Answer)

interleukins are produced, activating T helper cells to rapidly divide by mitosis - clonal expansion

#7
Front (Question)

stage 4 (differentiation)

Back (Answer)

cloned T helper cells differentiate - T memory cells - T killer cells - T regulator cells

#8
Front (Question)

what are T regulator cells?

Back (Answer)

suppress immune response so that cell mediated response only occurs when pathogens are detected

#9
Front (Question)

state 2 examples of T helper differentiation in terms of interleukins

Back (Answer)

• produce interleukins to activate B lymphocytes • produce interleukins to stimulate macrophages

#10
Front (Question)

describe T killer cells

Back (Answer)

• destroy abnormal/infected cells • release perforin which embeds in pathogen cell membrane and creates a pore; allows substances to exit and enter, causing cell death • common in viral replication • body cells are sacrificed to prevent viral replication
