How KSHV hides from the immune system via complement and Fc-receptor proteins

Immune Evasion Mechanisms of KSHV Complement and Fc-Receptor Proteins

NIH-funded research Texas Tech University Health Sciences Center at El Paso · NIH-11261173

Researchers are looking at how the virus that causes Kaposi sarcoma (KSHV) uses complement and Fc-receptor proteins to hide from the immune system, to help people with KSHV-related cancers.

What this research studies

From a patient's perspective, the team made a version of KSHV that lacks a viral complement control protein (KCP) and produced new antibodies to detect KCP. They used bacterial artificial chromosome (BAC) technology to engineer the recombinant virus and compare infected cells with and without KCP. Lab experiments include binding and bioassays to see how KCP and Fc-receptor proteins change immune recognition and cell survival. The goal is to reveal how the virus evades immune defenses and point to targets that could be used for future therapies or vaccines.

Who could benefit from this research

Good fit: Ideal candidates would be people living with KSHV infection or with KSHV-related conditions such as Kaposi sarcoma, multicentric Castleman disease, or primary effusion lymphoma.

Not a fit: People without KSHV infection or with cancers unrelated to KSHV are unlikely to gain direct benefit from this lab-focused research.

Why it matters

Potential benefit: If successful, this work could identify viral targets for drugs or vaccines that help the immune system control or prevent KSHV-related cancers.

How similar studies have performed: Other research has shown herpesviruses use similar immune-evasion strategies, but creating a KCP-null recombinant KSHV and new anti-KCP antibodies represents a relatively novel and less-tested approach.
