This blog post is about: In order for the immune system to properly protect an individual, the T-cell population needs to be composed of various subsets, each specialized to react to different types and stages of infections. Dr. Brian Rudd, an Assistant Professor of Immunology at the Cornell School of Veterinary Medicine, focuses on understanding the cell intrinsic differences within the T-cell repertoire of neonates versus their adult counterparts. Rudd seeks to answer the question: what makes a T-cell behave like a T-cell and understand why these two populations behave differently from one another.
