Toll-like Receptor Type 2 and 13 Gene Expression and Immune Cell Profiles in Diploid and Triploid Sterlets (

Summary: Fish have a built-in alarm system to fight off germs like bacteria and viruses. This system uses special sensors called Toll-like receptors. Scientists looked at a type of fish called the sterlet. Some sterlets are normal (diploid), while others have extra DNA (triploid). This study checks how having extra DNA changes their immune system and how well their germ sensors work to keep them healthy.
