Antworten
  • True
  • False

Frage 2

Frage
Which of the following are NOT professional antigen presenting cells?
Antworten
  • Neutrophils
  • Macrophages
  • Dendritic cells

Frage 3

Frage
CD8 T-cells recognise which MHC complex?
Antworten
  • MHCI
  • MHCII

Frage 4

Frage
CD4 is for the detection of virally infected cells
Antworten
  • True
  • False

Frage 5

Frage
CD4 cells recognise MHCII, which uses which Antigen processing system?
Antworten
  • Endosomal
  • Endogenous
  • Endomal

Frage 6

Frage
Cells with MHCI present using the endogenous AP system
Antworten
  • True
  • False

Frage 7

Frage
T- cells cannot recognise soluble, native antigens
Antworten
  • True
  • False

Frage 8

Frage
Put the following steps in the correct order- A (Antigen-MHC Complex Formation), B (Uptake), C (Presentation) and D (Degredation
Antworten
  • B-D-A-C
  • A-B-D-C
  • A-C-B-D

Frage 9

Frage
Which of the following definitions is incorrect?
Antworten
  • Uptake- picking up of the antigen from surrounding fluid
  • Degredation- total digestion of the antigen
  • Presentation- movement of the complex to the cell surface

Frage 10

Frage
Endosomal Pathway- What is it for?
Antworten
  • Processing of extracellular antigens picked up by antigen presenting cells
  • Processing of cytosolic viral antigens

Frage 11

Frage
Endosomal Pathway- Uses the MHCI complex
Antworten
  • True
  • False

Frage 12

Frage
Endosomal Pathway- The extracellular antigen is picked up by phagocytosis
Antworten
  • True
  • False

Frage 13

Frage
Endosomal Pathway- How is picking up of the antigen mediated?
Antworten
  • Receptor mediated
  • Compliment mediated
  • Hormone mediated

Frage 14

Frage
Endosomal Pathway- The antigen containing endosome only binds to the MCHII containing endosome after partial digestion
Antworten
  • True
  • False

Frage 15

Frage
Endosomal Pathway- How is the active site of MHCII covered in the cell?
Antworten
  • Covered by an invariant 'cap'
  • The two parts are connect by a subunit that must be removed
  • Receptor surface is bound to the endosome envelope

Frage 16

Frage
Endosomal Pathway- The cover of the MHC complex is called a CLIP
Antworten
  • True
  • False

Frage 17

Frage
Endosomal Pathway- How is the processed antigen added to the MHCII complex?
Antworten
  • Acessory proteins swap the CLIP for the peptide when the two vesicles fuse
  • Acessory proteins remove the MHCII from the envelope when the two vesicles fuse
  • Acessory proteins remove the subunit connecting the two halves when the two vesicles fuse

Frage 18

Frage
Endogenous Pathway- Main use is for what?
Antworten
  • Viral antigen processing
  • Professional pesentation of antigens

Frage 19

Frage
Endogenous Pathway uses MHCII
Antworten
  • True
  • False

Frage 20

Frage
Endogenous Pathway- How are cytosolic antigens processed?
Antworten
  • By the TCR
  • By MHCI
  • By cytosolic proteases

Frage 21

Frage
Endogenous Pathway- Digested peptides are moved into the Golgi by what?
Antworten
  • Transporter Associated with Antigen Processing (TAP 1&2)
  • Transporter Associated with Antigen Digestion (TAD 1&2)
  • Transporter Associated with Antigen Presentation (TAP 1&2)

Frage 22

Frage
In the Golgi the processed peptide is bound to MHCI and they complex is loaded into a vesicle for transport to the cell membrane
Antworten
  • True
  • False
