Question 1

How should reservoir frequency be reported?

Accepted Answer

With the assay named and its limit of detection stated. Different methods count different things, so a frequency without that context cannot be compared against published values. Report the number of cells screened, the enrichment applied, and the confidence interval, and avoid presenting a single measurement as a settled figure.

Question 2

How is latency distinguished from low-level production?

Accepted Answer

By positive evidence rather than absent signal. A sensitive assay for viral products, a treatment that blocks new rounds of infection, and confirmation that genome numbers stay stable together build the case. State the sensitivity achieved, since failing to detect production at a modest limit does not establish that none occurs.

Question 3

Why does asynchronous reactivation complicate analysis?

Accepted Answer

Because cells switch at scattered times rather than together, so a population measurement blends early switchers with cells that never respond. The resulting curve can be read as gradual induction when it reflects a small responding subset. Single-cell or time-lapse readouts separate the fraction responding from the timing of response.

Question 4

Which model system is appropriate?

Accepted Answer

It depends on the question, and the limits differ sharply. Cell-line models give tractability and scale but diverge from primary cells in chromatin state and signalling. Primary cells sit closer to the biology but are scarce and variable between donors. State which was used, why, and what the choice rules out.

Question 5

What controls does a reactivation experiment need?

Accepted Answer

A vehicle-matched unstimulated arm, a stimulus known to reactivate reliably in the same system, and a measure of cell viability, since many reactivation agents are also toxic. Without the viability control, cell loss can masquerade as a change in the responding fraction, and the two are easily confused.

Question 6

How should donor variability be handled?

Accepted Answer

As a feature of the data rather than noise to be smoothed away. Reservoir size and reactivation capacity differ substantially between individuals, so a mean across few donors is unstable. Report each donor separately alongside any summary, state the number used, and avoid drawing quantitative conclusions from very small sets.

Question 7

Does this work require access to clinical samples?

Accepted Answer

Not always. Neuronal and lymphoid model systems support a great deal of mechanistic work without them. Where cohort samples are needed, ethical approval, material transfer agreements, and collaboration arrangements take months and belong in the timeline from the start rather than being arranged once the laboratory work is underway.
