Title: Virginia Papaioannou: Innovator in Immunodeficient Animal Models

Introduction

Virginia Papaioannou is a prominent inventor based in Lexington, MA (US). She has made significant contributions to the field of immunology through her innovative research and patents. Her work focuses on the development of mutant RAG-1 deficient animals, which serve as valuable models for studying human lymphocyte behavior and related diseases.

Latest Patents

Virginia Papaioannou holds a patent for "Mutant RAG-1 deficient animals having no mature B and T lymphocytes." This patent details the process of generating immunodeficient animals by introducing a mutation in RAG-1 into the germline via gene targeting in embryonic stem cells. The resulting RAG-1 deficient mice lack mature B and T lymphocytes, which halts their differentiation at an early stage. This condition correlates with the inability to perform V(D)J recombination. The patent outlines that these mice do not express immunoglobulin or T cell receptors. Furthermore, the same strategy can be applied to create other RAG-1 deficient animals, such as rabbits, rats, and pigs, which can be utilized for various research purposes.
