Ratner Laboratory Research Interests

The long term interest of our laboratory is to define the interactions between glial cells and axons during nervous system development and how those interactions go awry in disease, with the goal of providing novel therapies to patients with nervous system diseases.  Neurofibromatosis type 1 (NF1) is a inherited autosomal dominant disorder (1:3500 humans) that involves the formation of many nerve-associated tumors and other non-tumor related problems.  Neurofibromatosis type 2 (NF2) involves the development of schwannomas, benign tumors composed of Schwann cells (peripheral glial cells).  Elucidating the mechanisms by which the nerve-associated tumors arise in both diseases can not only lead to the development of therapy for NF1 and NF2 patients, but can also useful in providing information about non-inherited nervous system cancers.

Current Projects

  
Identifying cell types involved in neurofibroma formationCharacterizing the role of Merlin in Schwann cells
Identifying alterations in NF1 mutant Schwann cells that may be relevant to neurofibroma formation and to the development of malignant peripheral nerve sheath tumors (MPNST, life threatening tumors)Delineating Oligodendrocyte (Central Nervous System, CNS,  glial cell) development in the absence of Nf1
Defining the precise function of specific Ras proteins in mediating normal Schwann cell and NF1 mutant Schwann cell phenotypes
