How does malaria’s blood-stage transcriptome unfold?

Plasmodium falciparum’s 48-hour intraerythrocytic cycle was profiled hourly, revealing tightly staged gene-expression programs after RBC invasion.

What cycle was profiled?

The asexual intraerythrocytic developmental cycle (IDC).

At what temporal resolution?

1-hour timescale.

How long is the P. falciparum IDC?

About 48 hours.

How does the IDC begin?

Merozoite invasion of red blood cells.

What forms after invasion in the ring stage?

The parasitophorous vacuole (PV).

What phase follows the ring stage?

A highly metabolic maturation phase, the trophozoite.

Why is P. falciparum important?

Causes most malaria episodes and substantial mortality worldwide.

Teaching point?

Pathogen developmental programs can be read as ordered transcriptomes through the host cell cycle.

Host cell type?

Human red blood cells.

What product is the paper’s main resource?

A high-resolution IDC transcriptome.

Best topic framing?

Host–pathogen biology via stage-specific gene expression.
