apoptosis - California (South)

Question

TNF family receptors may trigger the extrinsic form of this process upon viral infection, which viruses may deliberately induce to assist viral particle spread. For 10 points each:

[10e] Name this orderly process of programmed cell death often contrasted with necrosis.

ANSWER: apoptosis

[10m] The E1B 19K protein of adenoviruses blocks mechanisms of apoptosis both dependent and independent of this protein. Normally, this protein arrests the cell cycle at the G1/S (“G-one-S”) checkpoint in response to DNA damage.

ANSWER: p53 [or TP53; or tumor protein 53]

[10h] Viruses engage in the apoptotic form of this phenomenon by expressing phosphatidylserine (“phospha-tidyl-serine”) on their envelope. The immune system attacks the proteolipid protein of myelin after mistaking it as hepatitis B protein in this phenomenon’s “molecular” form.

ANSWER: mimicry [accept apoptotic mimicry; accept molecular mimicry; or word forms like mimic]
