Infection begins when the dengue virus uses receptors on an immune cell's surface to gain entry and release its genome.
Dengue virus has sophisticated mechanisms for entering a cell, for replicating its RNA genome, and for translating proteins.
How HIV infects a cell and replicates itself using reverse transcriptase and the host's cellular machinery.
The dengue virus's outer envelope proteins form symmetrical units and overlay the lipid envelope, capsid, and the RNA genome.
A visual representation of the U.S. AIDS epidemic from 1981 to 1997. Each dot represents 30 cases.
The geometric structures of viruses are beautiful and can be used, along with genomic information, to identify them.
Delivering a single virus to a cell allows the virus to infect the cell, replicate, and give rise to many progeny viruses. These viruses can then infect many neighboring cells.
