Antigen processing and presentation

Antigen processing and presentation

Multiple Choice

Which of the following DOES NOT play a role in antigen presentation

• MHC Class I molecule

• MHC Class II molecule

• MHC Class III molecule

• None of the above

Multiple Choice

Identify the structure

• MHC Class II molecule

• MHC Class I molecule

• Ig G

• IgA

Multiple Choice

Foreign antigens presented on class I MHC molecules...

• stimulate other immune system cells to respond to the antigen.

• stimulate macrophages to respond to the antigen.

• stimulate cell destruction by macrophages.

• stimulate cell destruction by activated T-cells.

Multiple Choice

The sequence for the processing of proteins produced within the cell is...

• Proteins are broken into fragments, transported to the rough endoplasmic reticulum, fuse with a Golgi vesicle containing class II MHCs, and this complex is transported to the plasma membrane.

• Proteins are broken into fragments within a vesicle, which fuses with a Golgi vesicle containing class I MHCs, and this complex is transported to the plasma membrane.

• Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class I MHCs, move to the Golgi apparatus, then to the plasma membrane.

• Proteins are broken into fragments, transported to the rough endoplasmic reticulum, combined with class II MHCs, move to the Golgi apparatus, then to the plasma membrane.

Multiple Choice

Fragments of foreign proteins are antibodies

• true

• false

Multiple Choice

choose the correct statement

• All cells express class I MHC molecule

• exogenous antigens are processed by endocytic pathway

• class III MHC genes encode membrane bound proteins

• MHC molecules are lipoproteins

Multiple Choice

CLIP IS

• CLASS II ASSOCIATED INVARIANT CHAIN PEPTIDE

• CLASS III ASSOCIATED INVARIANT CHAIN PEPTIDE

• CLASS I ASSOCIATED INVARIANT CHAIN PEPTIDE

• COMMON INVARIANT CHAIN PEPTIDE

Multiple Choice

Cross presentation of exogenous antigens is done by -------- as it has great advantage for the host.

• B Cells

• Dendritic Cells

• T cells

• NK cells

Multiple Choice

Fragments of foreign proteins are antibodies

• true

• false
