Novel approaches to quantify defective interfering particle activity reveal a surrogate marker of interference in mammarenaviruses
Defective interfering particles (DIPs) profoundly influence viral replication and host responses yet it remains difficult to quantify their activity routinely in the laboratory. Here, using lymphocytic choriomeningitis virus (LCMV) as a model mammarenavirus, we establish complementary approaches for measuring interfering activity of DIPs across a range of experimental scales. First, we optimized…
