= 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.

== Things to show ==

{{{
BLAST PDB for gp120, ~15 structures.
MAV showing sequence variations.

SAXS profile of gp120 / FAB / CD4 complex.

Physical model of gp120 trimers in 5 parts with bound CD4 and FAB
connected by magnets.

Cytoscape showing clustered HIV sequences clustered into clades
with associated PDB structures.

Glycosylation of gp120 (>50% of mass) illustrate glycans
with filled rings.

Inertia ellipsoids to show FAB orientations on gp120.

Fetch by id download caching.

Only one gp120 (SIV) has glycans.  Might demonstrating adding
them to naked gp120?
