Immune system surprise hints at new strategy for fighting HIV

An immune system response to microbial invaders is triggered when a family of receptors found in immune cells called Toll-like receptors are activated by invaders.

To the surprise of the Yale team, the researchers found that when a Toll-like receptor inside the CD4 immune cells, which are regularly destroyed by HIV, are blocked, it actually depresses — not activates — an immune system reaction.

Researchers now want to investigate whether manipulating this receptor could combat HIV infection.
