Diane McMahon-Pratt, PhD



The research in Professor McMahon-Pratt's laboratory is concerned with the parasitic protozoan, Leishmania, which causes a spectrum of diseases known as leishmaniasis. The laboratory is interested in understanding the immune effector mechanisms in the mammalian host that are involved in the control of infection and/or pathogenesis, with the aim to developing a vaccine against leishmaniasis. The laboratory has defined target vaccine candidate molecules and is collaborating with the University of Iowa and Cambridge University in a project directed toward the development of a multi-subunit vaccine. In addition, we have collaborated with Dr. Tarek Fahmy (Yale Bioengineering) in the development of nanoparticle therapeutic treatment delivery system for leishmaniasis. In other studies, the laboratory also collaborates Drs. Al Bothwell and Eddie Chae (Immunobiology) investigating the role of DKK-1 in the regulation of the innate and T cell responses to Leishmania infection. We have long-term collaboration with scientists in Colombia. Currently, Professor McMahon-Pratt is director of NIAID R01 and Fogarty (NIH)-sponsored Programs with Centro Internacional de Entrenamiento e Investigaciones Médicas (CIDEIM) in Colombia. These programs are focused on understanding the pathology of leishmaniasis caused by Leishmania (Viannia), which predominates in South America, with the objective of designing immunological approaches for treatment and control.

Education & Training

  • Post-Doctoral Fellow
    Harvard Medical School (1980)
  • PhD
    Harvard University, Immunology (1978)
  • BS
    University of Southern California, Chemistry (1969)


  • Improved Treatment of American Cutaneous Leishmaniasis by Immunomodulation
    Colombia (2011-2015)
    This application is a collaborative project with Dr. N. Saravia at CIDEIM (Colombia) which is focused on the development of immunomodulatory therapy for cutaneous leishmaniasis caused by Leishmania (Viannia). The murine model of chronic disease is being used to interrogate new approaches for treatment.
  • Vector/Host-Parasite Interface of Leishmaniasis in Colombia
    Cali, Valle del Cauca, Colombia (2004-2018)
    The goal of the training grant is to build research capacity to identify strategies and devise means to interrupt the cycle of transmission and pathogenesis of leishmaniasis through intervention of the invertebrate and vertebrate host pathogen interactions. To achieve this goal, the training program will implement research capacity in the molecular analysis of the interaction between Leishmania and both the sandfly vector and the mammalian host. The proposed program builds upon the existing rese
