Novel drug shuts down master protein key to lymphoma

Spleen, Diffuse Large B Cell Lymphoma

Researchers have discovered how an experimental drug is capable of completely eradicating human lymphoma in mice after just five doses. The study, led by researchers at Weill Cornell Medical College, sets the stage for testing the drug in clinical trials of diffuse large B-cell lymphoma (DLBCL), the most common subtype of non-Hodgkin lymphoma, itself the seventh most frequently diagnosed cancer in the U.S.

In a study published in March in Nature Immunology, Dr. Melnick and his team reported that it is possible to shut down Bcl6 in DLBCL without affecting its vital role in the T cells and macrophages needed to support a healthy immune system. The protein has long been considered too complex to target with a drug as it also is crucial to proper function of many immune system cells, not just B cells gone bad.
