Question 7

Why are researchers attempting to express cholinein-1 and CdtVEGF in Pichia pastoris?

A) Heterologous expression in P. PASTORIS may allow scalable production of these venom-derived molecules for improved biopharmaceutical applications.
B) P. PASTORIS enhances the toxicity of venom proteins, increasing their therapeutic potency.
C) Yeast-based expression eliminates the need for purification of recombinant proteins.
D) The yeast naturally produces fibrin sealant components without genetic modification.

Answer 7

Correct Answer:
A) Heterologous expression in P. PASTORIS may allow scalable production of these venom-derived molecules for improved biopharmaceutical applications.

Question 8

Why do researchers describe the immune reaction to the dendritic-cell–tumor-cell fusion vaccine as “violent”?

A) The vaccine causes rapid destruction of healthy tissue surrounding the tumor
B) The immune system interprets the fused cells as a transplant and mounts an intense response
C) The fused cells replicate uncontrollably inside the patient
D) The vaccine triggers severe allergic reactions in most patients

Answer 8

Correct Answer:
B) The immune system interprets the fused cells as a transplant and mounts an intense response

Question 9

What is a major challenge in producing dendritic cells for personalized cancer vaccines, according to Barbuto?

A) Dendritic cells generated from monocytes often become excessively cytotoxic.
B) Lab-generated dendritic cells frequently induce immune tolerance rather than activating an anti-tumor response.
C) Dendritic cells fail to survive long enough in culture to be therapeutically useful.
D) Monocytes cannot be reliably isolated from cancer patients’ blood.

Answer 9

Correct Answer:
B) Lab-generated dendritic cells frequently induce immune tolerance rather than activating an anti-tumor response.

Question 10

What is the primary purpose of fusing dendritic cells from healthy donors with cancer cells from patients?

A) To generate universally compatible dendritic cells for all cancer patients
B) To create a personalized vaccine that activates the patient’s immune system against their own tumor
C) To suppress immune activity and reduce inflammation around tumors
D) To replace the need for chemotherapy in early-stage cancers

Answer 10

Correct Answer:
B) To create a personalized vaccine that activates the patient’s immune system against their own tumor
