Teaching B cells to make powerful HIV-blocking antibodies

In vivo engineering of B cells for the secretion of HIV broadly neutralizing antibodies

NIH-funded research Scripps Research Institute, the · NIH-11232304

This project uses gene editing to reprogram your B cells so they can produce long-lasting antibodies that block many strains of HIV.

What this research studies

Researchers use precise gene-editing tools (CRISPR) to insert genes for broadly neutralizing HIV antibodies into a person’s own B cells so those cells act as antibody factories. They deliver the editing tools directly to target cells using AAV-based vectors and then give HIV Env vaccines to trigger the engineered B cells to expand and mature. In early work, this approach produced durable, switched antibody responses in mice after vaccination. The goal is to generate sustained antibody levels from a small number of edited B cells to control or prevent HIV over the long term.

Who could benefit from this research

Good fit: Adults living with HIV or people at high risk for HIV who meet safety and eligibility criteria for an experimental gene-therapy trial would be the likely candidates.

Not a fit: People with severe immune suppression, certain blood disorders, active infections, pregnancy, or those unwilling to accept gene-therapy procedures may not be eligible or benefit.

Why it matters

Potential benefit: If successful, this could provide long-lasting HIV protection or control from your own immune cells rather than repeated antibody injections.

How similar studies have performed: Giving bnAbs directly or using AAV to deliver antibody genes has shown promise in animals and some human work, but directly editing B cells inside the body is a novel approach that has so far succeeded only in animal studies.
