The Research & Development (R&D) Division at Amerimmune consists of a group of scientists committed to relating basic immunological science with symptoms and disease progression to better understand diseases and mechanisms with which to target when determining biomarkers for diagnosis or treatment options.

The scientists of our R&D team are intimately familiar with the immunodeficiency within the community and desire to shed more light on them.  They also want to provide deeper insight to the physicians who treat them. Therefore, all the R&D projects and collaborations here at Amerimmune aim to not only bring more knowledge into the basic science field of immunology, but also to the translational field of immunology.
