This Jawless Fish Could Help Treat Brain Diseases

Lampreys, ancient jawless fish, have unique immune systems with variable lymphocyte receptors (Vlr's) that directly attack pathogens. These Vlr's can be engineered to target specific diseases, offering potential for treating brain diseases like cancer. A study demonstrated Vlr's delivering chemotherapy drugs directly to brain cancer sites in mice, improving survival rates. This method could revolutionize treatments for various brain diseases by minimizing side effects. Future research may expand Vlr applications to other medical fields.
