HIV Spike Demo Storyboard

Storyboard for HIV spike demonstration for RBVI advisory committee meeting on November 13, 2009.

Aim of demonstration

Aim is to show EM, sequence, and network visualization tools applied to a single biological problem.

Biological Problem

The specific biological problem is to understand interactions of broadly neutralizing antibodies (bNAb) with HIV spike proteins gp120 and gp41. The spikes recognize CD4 receptors on human T-cells to identify and infect those cells. The motivation is to develop an HIV vaccine which works by eliciting production of these antibodies. This month two new bNAbs were reported that are effective against more HIV strains and at lower antibody concentrations than the previously known half-dozen bNAbs.
