Vaccine development

CD8 T cell priming occurs in two phases. In the activation phase (day 1), naïve T cells engage with dendritic cells (DC) for 24 hours, then detach, proliferate, and move deeper into the lymph node. In the selection phase (days 2-3), activated T cells regain sensitivity, re-engage with antigen-presenting cells, and receive IL-2 support from CD4 T cells. Regulatory T cells limit IL-2 availability, driving the expansion and differentiation of high-affinity CD8 T cells into effector cells.

Transmission electron micrograph of HIV-1 virus particles (blue) from infected H9 cells, produced in cell culture. The particles exhibit two stages of replication: the two “arcs” are immature particles budding from the plasma membrane of the cell, and the center spherical particle is a mature form in extracellular space.
