Kojo Elenitoba-Johnson, MD received a medical degree from the University of Lagos College of Medicine, in Lagos, Nigeria, and underwent residency training in Pathology at Brown University. Dr. Elenitoba-Johnson received subspecialty training in hematopathology under the supervision of Dr. Elaine Jaffe at the National Cancer Institute, at the National Institutes of Health, and is board certified in combined Anatomic and Clinical Pathology, with subspecialty certification in Hematology, and Molecular Genetic Pathology.
Dr. Elenitoba-Johnson is currently an Associate Professor of Pathology at the University Of Michigan Medical School and is the Director of the new Division of Translational Pathology at the University of Michigan Medical School.
Dr. Elenitoba-Johnson's laboratory has been interested in characterizing the molecular events underlying transformation of follicular lymphoma to aggressive diffuse large cell lymphoma. Previous work implicated alterations involving the cyclin dependent kinase inhibitor p16INK4A in the pathogenesis of follicular lymphoma transformation. Using gene expression profiling, they subsequently demonstrated that several deregulated growth factors and cytokine receptor genes signaling through the mitogen-activated protein kinase pathway play a role in the progression of follicular lymphoma to diffuse large B-cell lymphoma. This study highlighted the complexity of deregulated processes involved in lymphoma progression, and provided evidence for the activity of an autocrine-paracrine feed-back loop involving growth factors, cytokines and their receptors in the pathogenesis of follicular lymphoma transformation.
